    V The invention relates to equipment installed in production wells and can be used in the course of exploration using geophysical methods during operation, a well-known contact device for connecting cables to installations that are located in a well. The disadvantage of the device is that to replace the installation, it is necessary to remove the drill string from the well. The closest to the invention in terms of technical suitability is a device for installing the device 3, the wellbore / false column, containing percodg ::;.; having a side socket for receiving an instrument lowered on the inside of the drill string and a connecting cable. However, a preliminary pr-ed device is designated only for installing purely mechanical elements., TaKHXjKa gates, the purpose: the inventors 1-g is to ensure that the device is replaced without raising the column. The goal is achieved by the fact that a device containing an adapter 5 having a side socket for the device, is provided with a contact assembly installed in the lower part of the socket and a cable connected to it, which is attached to the other side of the socket. On the surface of the column ,, sig 1 schematically shows a drill kolonnaz configured polm chuck (adapter) in which is mounted measuring device ny, longitudinal section; in fig. 2 - column, with a detailed image of the cartridge; cha fig. 3 shows section A-A in FIG. 2; in FIG. - 4 — times, cuts. B — B in FIG. 2; FIG. 5 - section bb in fiGo2; on figb - section GG in figure 2; FIGS. 7 and 8, a measuring device installed in the cartridge, longitudinal sections; FIG. 9 - electrical connection of the cartridge and measure;,: the device. The device contains a cartridge 1, which is adapted to fit the measuring clamp 2 and is installed between light cylinders 3 and 4 of the drill string. The connections of the cartridge 1 with the drill string are made with the help of conventional threaded couplings 5 and 8. Parts 7 and 8 of the cartridge 1 have the same diameter with the drill string, and the internal eccentric section of the middle part 9 is made with a large diameter, the junction of the sections is provided tapered walls 10 and 11. In the middle part 12 of the cartridge equipped with a slot 13, which provides longitudinal movement, with a cross section at least equal to the cross section of the drill string in areas of the ground; Items 3 and 4, On the bottom of the socket 13 where the measuring device 2 is installed, a connector 15 is connected to a single-core cable 14 having a lead to the surface. When installing the measuring device 2 into the socket, the connector 15 isolates the electrical connection of the measuring device and the cable 14, which provides the voltage supply to the device and the transmission of information to. surface. The cartridge 1 (Figures 2-7) consists of two elements machined on the walls and butt-welded (welding point 16), and the side slot 13 provided with the part is sealed inside and secured at its ends in the middle part 9 of the cartridge. The side slot 13, which is angled to the axis of the drill string, consists of an upper part 17 of a semi-circular section (FIG. 4) and a lower part 18 of a tubular section, which has a longitudinal notch 19 (FIG. 5). The upper part 17 has an inlet conical opening 20 to facilitate the installation of the measuring device and is attached to the body of the cartridge with screws 21 (Fig. 4), which, by welding, ensure the tightness of the structure. The internal groove 22 of the upper part 17 allows the fixation of the device in the socket. The bottom part 18 of the socket 13 (Fig. 9) has a tide 23 welded between the central part 9 and the bottom part 8 of the cartridge and ending at the bottom with a partition 24 with an Euro-vertical groove 25 and an inclined hole 26, Above the partition 24 there is an internal conical bore 27 having a neo-acid The current carrying cover, for example, from a rod, on which the lower end of the measuring device rests.
    Along the axis of the bore 25, another bore -28 of a larger diameter is made than the first one passing through the conical partition of the cartridge 1,
    The rectangular groove 29 (FIG. 6) is cut from the outside of the cartridge in the partition. It serves as a socket for the nut, which is rigidly fastened to the cartridge relative to the chuck and provided with a nut 30 of special construction, having a flat cut.
    A coupling 31, mounted with a threaded joint inside the nut 32, holds a 28 pin connector 15 in the bore, the Contact plug 15 consists of a tubular metal body 33 having a shoulder 34 that abuts the lower face of the partition 24, and a shoulder 35 resting on the coupling 3 A conductive rod 36, consisting of a cone-shaped head 37 and passing along the axis of the bore 38 through the entire housing 335, is insulated with a glass coupling 39. The metals from which the rod and the housing 33 are made have an expansion coefficient as close as possible to glass expansion. The upper part of the glass sleeve 3 is an annular contact 40 enclosed between the housing 33 and the head 37 along the outer perimeter. Gaskets 41 provide tightness of the design between the housing 32 and the cartridge.
    At its lower end, the conductor 1 st rod 36 is connected with a conventional hermetic plug connector 42 (FIG. 2) to the conductor strap 43 of the cable 14.
    This design method provides the contact connector 15 with the ability to withstand the adverse environmental conditions (temperature, pressure, shock load and corrosive environment) that are encountered in drilling wells. This feature is of greater interest because the contact connector is constantly in the well and can be replaced only after the drill string is removed from the well.
    Despite its seeming simplicity, this pin connector performs
    .dual function, on the one hand, it is a hermetic vyshod through the wall of the cartridge, with the other due to the upper contact surfaces (one conductive, and the other insulating), it allows an insulated electrical connection to the measuring device in a conductive medium,
    The measuring device 2 (Fig.7 and 8) consists of a blocking device 443 of the measuring device 45 and the plug connector 46.
    The locking device of the usual type together with the groove 22 is intended for fixing the measuring device in the socket of the cartridge. This device is similar to the one used to install and lift onto the surface of the gates
    Inside the housing 47, a latch 48 is movably mounted, which under the influence of the coil spring 49 can be rotated clockwise. A locking rod 50, secured with a pin 51, does not allow the latch 48 to move below the position indicated in Fig. 7.
    When installing a measuring device in the socket, the latch 48 is pushed upward until it takes a position corresponding to the groove 22. The locking rod 50 prevents the latch 48 from lowering while holding the measuring device in the socket. The head 52 is screwed onto the upper end of the stopper rod 50. To remove the measuring device from the socket, the device for extracting is mounted on the head 52 and then pulled up, and the applied force must cut the pin 51. The rod 50 moves upwards and releases the latch 48. Measuring device no longer held in its nest and can be pulled to the surface. The locking device 44 in its lower part has a telescopic device that allows you to simultaneously perceive the shock load on the measuring device and hold the plug connector 46 pressed to the conical bore 27. At the lower end of the housing 47 the tube 53 is movably mounted, the stroke of which is limited by a pin 54. fastened on top
    S
    the end of the tube 53 with the ability to move in diametrically opposed longitudinal grooves 55 cut out in the housing 47.
    The spring 56e is compressible with an E-Peplek 57 trumpets-e 53 and the bottom edge of the body 47, moving downward the tube 53 relative to the body. The tube 53 is screwed on by a kg coupling 58, which is part of the measuring device 45, in this case represented by a pressure gauge. The clutch 58 is elongated in the form of a column 59, around which the bellows BO is installed; which in their upper part end with cap 61; fitted with a filler plug 62
    In column 59, there is a vertical channel 63 filled with oil, as well as slit 60. The oil pressure in channel 63 acts on a pressure sensor 64 which is attached by means of a threaded connection to the coupling 58. The ambient pressure is transmitted to the bellows 60 through side holes 65 In the tube 53, the connector 58 from the bottom is terminated by a tubular support 66 placed inside a sealed enclosure 67 which, in turn, is attached to the coupling sleeve by a threaded connection. On base 68, electric circuits are laid (block 69 in the drawing). These circuits are connected on the one hand to the sensor 64 by means of a current; cable 1d) iain cable 70, and on the other by means of a conductive wire 71 to a wire conductor pin 72 of the hermetic terminal 73, which is attached by means of a threaded connection to the bottom of the housing 67,
    As a pressure sensor 64, a membrane can be used which is deformed under pressure and to which voltage sensors assembled in a bridge circuit, powered by a constant current, are attached. The output signal from sensor 64 is supplied via an electrical circuit 69, which typically includes a voltage and frequency amplifier, whose input signal can be applied to a direct voltage supply of the sensor. This device allows you to perform a measuring device.

    MO ii,
    The connecting device (connector) 46 (Fig. 9) consists of a non-existent tube 74, fastened with a threaded connection to the lower part of the body 67, in which the side holes 75 are made.
    The rigid fastening of the sealed 10th outlet 76 with the plug connector 77 is carried out in the tube 74. On the lower part of the conductive pin 78 a metal nozzle 79 is screwed to which the conductive
    iS coil spring 80, the lower end of which is attached to contact 81. Contact Si; conductive conductive spring 80, nozzle 79 and part of hermetic seal 76 are filled with an insulating layer
    .0 elastomer 82. Thus, the contact 81 has the possibility of longitudinal movement within the tube 74. The connecting device includes a mechanism for ensuring 5 isolation of the electrical connection of the contact 81 and the head 37 from the environment of the well. Elastic insulating sheath 83, resting on top of elastomer 82,
    30 has a thickened bottom that is rigidly attached to the metal tube 84.
    Metal tube 84, installed with a relative gap
    J inner tube 74 is held in a vertical position by pins 85. The lower portion of tube 74 has a non-acidic conductive conical outer part 86 in the shape of a conical bore 27 of slot 13 (Fig. 9) to provide electrical contact, which allows the current to travel back through mass of
    Inner Lyska 87 provides
    5 the introduction of the tube 74 in the contact device 15.
    With the expansion of the spring (Fig.8) contact-clip 81 locks the lower end of the shell 83, leaving only a small gap between the contact and
    the inner surface of this shell. The space between the elastomer 82 and the shell 83 is filled with a vista when the device is installed.
    3 dielectric fluid, such as silicone.
    After installing the measuring device in the socket even provided. that the environment has managed to penetrate this space, the electrical connection of the contact head 37 and the contact 81 will be isolated from the tube 74 and: the environment of the well through the shell 83, the inner face of which, located inside the tube 84, rests on the contact surface 40 of the insulating sleeve 39 In the case when it is necessary to make systematic measurements, a cartridge 1 is installed in a production well at a certain height of the drill string. The slot 1.3 is equipped with a contact device 15 connected to the cable 14, which is attached along the drill string and builds up as the string is lowered into the well. The drill fines accumulating in the socket are discharged through the inclined opening 26. The installation of the instrument is carried out as follows. The measuring device 2 is fastened in the position indicated in FIG. 7 and B, in the lower part of the tool, using a pin 88, which is then lowered onto the cable into the borehole to the depth of the cartridge. Maneuvering by alternately raising and lowering, the device should be set to the position corresponding to the socket. The device is then inserted into the socket, which is fixed by inserting the latch 48 into the internal bore 22. As soon as the device takes a fixed position, the contact device 15 enters the lower part of the elastic shell 83, thus providing electrical contact between the head 37 and the contact 81 of the plug connector 77. The fluid inside the shell 83 is discharged through the top.
    the hole and extends between the upper part of the shell and the elastomer 82. The shell 83 rests on the contact surface 40 of the glass sleeve 39, forming a chamber around the head 37 50 of the contact 81, which isolates this contact from the environment of the well. Then, cut the pin 88, release the device for mounting the device and lift it 55 to the surface. Measuring device 2 is ready for operation as soon as voltage is applied across the cable 14. 1
    In particular, as a measuring device installed in a drill string, there may be another device other than a manometer, and the locking and connecting devices can easily be adapted to various types of electrical measuring devices.
    Other installation and extraction techniques are also possible using devices that are moved in the drilling rig by means of surge. 88 If it is necessary to perform maintenance and repair operations on a measuring device, the latter can be removed from its socket and lifted to the surface with the help of a special device similar to that used to install it. This fixture is lowered at the end of the cable into the drill string and picks up the head 52 .. When the cable is sufficiently tensioned, pin 29 is cut off, which releases the latch 48, and the device is removed to the surface. The phenomenon of suction, which takes place when the contact device 15 is removed from the shell 83, is explained radially with the latter. The internal volume of the shell 83 is large enough, which ensures complete removal of the contact device 15 from the shell. Thus, a measuring device for performing the necessary operations can be lifted with a cable and then reinstalled. Consequently, access to the device is provided without lifting the drill string from the well. The elements installed in the well and, in particular, the contact device 15 and the cable 14 are very simple and do not suffer from corrosion. On the contrary, all mobile elements, as well as the most complex, are located in the measuring device and can be easily retrieved to the surface. The installation and removal of the measuring instrument is carried out using devices known and widely used in practice. The described yano device is an example and may have various variants of the technical design and use of materials.
