    5 to feed drill cuttings. The drill rod 3 is hydraulically connected to the drilling control station 6, which consists of a receiver 7, fitted in the form of a pressure sensor installed in pipeline 5, an indicator 8 and a recording unit 9 connected to the receiver 7.
    The drill rod 3 (see Fig. 2) is a concentrically arranged inner movable pipe 10 with a central axial flushing channel 11 and an outer fixed pipe 12, on the surface of which the rails 13 are rotatably mounted.
    In the outer fixed pipe 12 is placed a set of measuring 14 and control 15 devices, which is connected to the inputs of the control system 16.
    In the outer fixed pipe 12 there are installed hydraulic booster cylinders (not shown) connected to guide rails 13, as well as a hydraulic pump 17 for creating a hydraulic working pressure, a telemetry device for transmitting information from a set of measuring and control devices, an electric current generator 18, the rotor of which It has a drive, for example, a gear wheel 19, the teeth of which are engaged with the inner movable pipe 10 so that the generator 18 is in turn driven from the pipe 10. Since
    Because the hydraulic pump 17 is driven directly from the rotating tube 10 or from the generator 18, the operation of the hydraulic booster as well as the energy for the measurement results and its transfer to the hydraulic booster are independent of the kinetic energy of the pulp flow. The generator 18 serves to generate energy for the measurement signals 14 and the control devices 15, for controlling the telemetry device for transmitting information, consisting of the pulp wash channel 20 and the hydraulic transducer for the measurement signals I4 and the control devices 15 for pulp pressure pulses, which contains a two-way control based on the embodiment according to fig. 3 shows the propagation of the working medium for actuating the two-way controlled piston 21 from a fixed external 12 at a decreasing Rotating tos inner tube 10 into the channel 28 of the piston 21. According to this bearing ramie 37 and 38 of the outer tube 12, made by the drilling tool 4, the inner pipe 10 planted a ring 39, which is closed by a pin non-rotatably
    15 40-with the inner tube 10 and on its outer side has an annular groove 41, 42 for supplying or, respectively, relieving the pressure of the two-way controlled piston 21.
    The movable piston 21, as well as for the control- 20 Both hydraulically annular grooves 41 and 42 are placed in a pipe 12 by a two-way three-way magnetic valve 22, which controls the hydraulic working medium of the two-way controlled piston 21. Magnetic valve 22 by means of control channels 23 and 24 connected to a controllable piston 21. The hydraulic pump 17 is protected by a pressure limiting valve 25 in the control channel of the ring conduit 26 to the reservoir 27, from which it is fed by the working fluid.
    According to the exemplary embodiments (see Fig. 3, 4 and 6), the two-way controlled piston 2 is a cylinder placed in a cylindrical piston channel 28 of the inner tube 10. In the piston 21 there are two end channels in which seals 29 and 30 are installed, and a third (middle) annular channel 31 for the passage of flushing fluid .. A piston compression spring 32 is installed in the piston channel 2b, one end of which abuts against the lateral end 33 of the piston 21 and the other end 34 of the cylindrical piston channel 28. Axial transverse bore 35 times The screw channel 28 and the hole 36 in the end face of the piston 2 form a hydraulic connection with a two-way three-position magnetic distributor 22.
    According to an embodiment of the two-way controlled piston 21 (see Fig. 8), the section for the piston 21 in the channel 28 ends in front of the flushing channel 31.
    Based on the embodiment according to FIG. 3, the working medium for driving the two-way controlled piston 21 from the fixed outer pipe 12 to the rotating inner pipe 10 into the channel 28 of the piston 21 is shown. According to this, before the bearing pairs 37 and 38 of the outer pipe 12, made from the side of the drilling tool 4, a ring 39 is mounted on the inner pipe 10, which is blocked without rotation by a pin
    40 has an inner tube 10 and on its outer side has an annular groove 41, 42 for supplying or, respectively, relieving the pressure of a two-way controlled piston 21.

    They are hydraulically insulated from one another and from the outside by means of O-rings 43-45 and inside by O-rings 46-48. Using radial channels 49 and 50, they are connected to the channels in the outer pipe, which form the inlet and outlet control channels 23, 24 and for the hydraulic working medium.
    The generator 18 is a low speed rotor with 60 rpm and produces an alternating voltage of 3 V 24 V with a required power of about 40 watts. Instead of the alternator 18, two DC motors can also be used.
    The electronic control system 16 has a power element containing a rectifier that converts three-phase current into a constant voltage and voltage regulator to maintain a voltage of 24 V. A voltage converter with a digital

    Along with power and electronic control systems, a transmitting electronic system is provided for receiving and transmitting measurement results or, respectively, signals from control devices (in particular, signals from two incline measurement devices for, for example, vertical wells transmitted by control voltage + 5 C). Due to this, the temperature of, for example, a hydraulic medium can be controlled in two places, which is carried out by means of a voltage signal of 0-5 V. In addition, a pressure of the hydraulic tank of 0-5 bar can be transmitted by a voltage signal of 0-5 V. The hydraulic nominal pressure of 0-100 bar, limited to this value, is also indicated by a constant voltage of 0-5 V, while the hydraulic pressure in the measurement data transmission system; 0-60 bar (spindle piston) is limited to this value and is transmitted by a constant voltage of 0-5 V. Thus, the generator voltage is controlled to be 18-38 V.
    According to the embodiment shown in Fig. 9, the diameter of the channel 28 for the piston 21 is larger than the diameter of the washing channel 31 placed in the projection of the channel 28. The piston 21 has a channel 51 that has the same contour and cross section as the washing channel 31, Groove 52 in the wall of the channel 28, the stop 53 interacts with the piston 21, so that the piston is fixed rigidly around its axis throughout its path and in the neutral position coaxial with the proma. Vocal channel. As a consequence, the movement of the piston 21 is limited to the residual part of the diameter in the area of its channel 51 and, as a result, is located outside the cross section of the flushing channel. Thus, the diameter of the flushing channel in the neutral position of the piston is not limited.
    The device works as follows.
    The device is placed in the borehole 54 so that the guide rails 13 rest on the walls of the borehole 54, and the outer pipe I2, when the drill mill of the drill pipe 1 and 2 rotates, gestures

    ko clamped. As a consequence, there is a relative rotation of the inner pipe 10 in the outer pipe 12.
    They serve a fine working environment.
    . If the magnetic distributor 22 is started and the corresponding aperture 36 is loaded or discharged, the working medium is either supplied in front of the face side of the piston 21 and is displaced from the cavity behind the end side of the piston so that the piston 21 instantly deviates, or, accordingly, the load occurs in the opposite direction. direction, whereby the two-way controlled piston 21 instantly returns to its original position.
    When the piston 21 is deflected, the flow of pulp through the flushing channel 31 is instantly strongly throttled or blocked for a short time. As a consequence, there is a sharp pressure increase in the industrial channel 31, which, after switching the magnetic distributor 22, also leads to a sharp drop in voltage, because the spring 32 instantly returns the piston to its initial position. As a result, rectangular pressure pulses occur (position 55 in FIG. 5). The double arrows marked above these pulses show the duration of the pulse, which is transmitted by increasing and decreasing pressure, to the next pulse in pressure. This pulse duration identifies the measurement result and the measurement signal. It is received by receiver 7 and converted to a voltage value.
    The double pulse duration indicated by the double arrow (position 56 in FIG. 5) identifies the other measurement signal, so that the piston 21 through the distributor 22, due to the high switching frequency achieved with its help, receives a multitude of measurement results and perfectly visible pressure signals of 1 and pushes the flow of pulp. Therefore, the differential pressure receiver 7 can convert these pressure signals into electrical signals that can be identified.
    For the described control systems, the number of which, if necessary, can be increased or decreased, five channels are required to transmit the measurement data according to the type depicted at 55 and 56 in Fig. 5. Thus, in the electronic control system 16, all five measurement results must be taken as voltage values ± 5 V or, respectively, 0-5 V, and analog-time conversion of the voltage of the measurement results should be carried out. According to this transmission. The electronic control system 16 must generate pulses, and the duration of the pulses, i.e. the time interval between two consecutive pulses corresponds to the voltage value of the measuring channel (8 channels - 9 pulses. In the electronic control system 16, the measurement results are cyclically read at the input and for eight channels - nine pulses are output to the output transistor, which in the corresponding clock a pulse (9 pulses) starts the magnetic distributor 22 of the two-way controlled piston 21. Thanks to the start of the piston 21, the column of flushing cutting in the drill pipe is modulated and pressure pulses received by the pressure differential receiver 7 at the control station 6 outside the well. If the sensitivity of the differential pressure receiver 7 is 0-100 mbar and when the power is 10-40 V, a current pulse of 0-20 mA can be output. transmitted via a two-core cable from receiver 7, regardless of the length of the wire.
    On the receiver 7 side, eight channels can be provided with a power supply of 24 V. In receiver 7, remote current pulses are converted into voltage pulses and serially transmitted. Receiver 7 determines the time intervals between pulses and converts them into voltage values. The output takes place in parallel on eight digital indicators ah v

    impulses whose time interval is always the same. By this, the electronic control system 16 and the receiver 7 are synchronized. Only after the receiver receives 7 flawless reception of these clock pulses, the measuring pulses are received, which eliminates transmission errors.
    The transmission accuracy is about 1.5% at + 5 mb. For tilt with a measurement range of + 1 °, this means a transmission error

    In the study of horizontal and directional wells, at least one compensatory accelerometer with electrical current feedback and at least one magnetic compass can be used as measuring devices, such as a deviation sensor and an azimuth direction sensor, since they are immune. to the associated rotation in the process of drilling and provide accurate receipt and transmission of the required measurement results.
    In the study of wells directed through the seams, it is advisable to attach one or more gamma-radiation sensors to the outer pipe, by means of which flawless probing of the bumps and lying sides is possible.
    Thus, besides the signals sent by the deflection sensors from the vertical, many other parameters of the directional drill rod may also be transmitted to the surface. At the same time, the necessary measuring and control devices can be placed in
