    In the representative embodiment of the new and improved wireline formation-testing apparatus disclosed herein, pressure-responsive fluid-admitting means and tool-anchoring means are cooperatively arranged on a tool body for selectively anchoring the tool in position in a well bore for obtaining at least one measurement or fluid sample from a sub-surface earth formation. The new and improved tool further includes a selectively-operable hydraulic pump which is coupled by a plurality of selectively-operable hydraulic valves to the pressure-responsive means as well as to one or more pressure-responsive flow-control valves. By arranging each of the hydraulic control valves to operate only at selected hydraulic pressures, the new and improved formation-testing tool is sequentially operated as required to obtain selected measurements and, if desired, one or more samples of the formation fluids from one or more formation intervals before removing the tool from the well bore.

    专利说明:

    This invention relates to hydraulic actuators for exploration devices, namely, hydraulic lines for samplers. A device for exploration of downhole formations is known, including several autonomous, sequentially installed samplers 1 However, the large weight and length of this device limits the possibilities of its use. A device for exploration of well formations is known, including. .borehole hole with hydraulic means for driving means and sample picker, hydraulically connected to the blocking valve, source of hydraulic energy connected to pressure and drain lines with hydraulic cylinders of the driving means and blocking valve, and control panel connected to the source food 2. The purpose of the invention is to increase the efficiency of the device. This goal is achieved by the fact that the device is equipped with a normally-closed control valve, the inlet of which is connected to the pressure line, and the outlet is connected to a blocking valve, and two normally-closed valves, the outlets of which are connected to the drain line, the inlet of one with the inlet, and the other - with the output of a normally-closed control valve. FIG. 1 shows the position of the device in the well; in fig. 2 and 3 - hydraulic circuit of the device in the initial position; in fig. 4 - B - the sequence of the positions of the elements of the device when sampling; in fig. 9-11 sequence of the positions of the elements of the device when returning to its original position. The device consists of a control panel 1 with a recording and indicating equipment connected to a power source, a source of hydraulic energy 2, made in the form of a tank 3 with a spring-loaded separating piston 4, a piston cavity 5, which is communicated by line 6 with the well at the sampling level, and A pump 8 with an electric motor 9 is located in the piston cavity 7. Drain 10 and retaining I lines come up to cavity 7, and pump 8 leaves the working line 12 and return line 13 from the pump 8. a and suspended on the cable 14 in the borehole 15 of the borehole projectile 16, the latter contains tanks 17 and 18 for samples, a sampler 19 and; hydraulic cylinders 20 - 23 for driving means for the driving means. Sampler 19 is a telescopic hydraulic cylinder with cavities 24-27, inner diameter. 28 of which is made with channel 29 communicated with line 30, is connected via valves 31-34 equipped with spring-loaded pistons with containers 17 and 18. Line 30 30 is connected with valve 36 by line 35 and is equipped with a spring-loaded piston. A line 12 is connected to an input of a normally closed control valve 37 consisting of a housing 38 with a seat, a needle 39, a piston 40 and springs 41 and 42, the output of which is connected by a line 43 with a normally closed valve 44 consisting of a housing 45 with a saddle, needles with a piston 46 and springs 47, the outlet of which is connected to the drain line 10. The inlet of valve 37 is connected to the inlet of the normally-closed valve 48, the outlet of which is connected to the drain of the pipeline 10. Valve 48 is made similar to valve 44. Cavities 27 and 24 of the sampler 19 are connected via valve 49, which is made similar to valve 37. Cylinders 20–23 are connected by rod cavities to line 13, and piston ones are connected to line 12. Cavity 25. sampler 19 is connected to line 12 and cavity 24 to line 13. Piston cavities of valves 37, 44, 48 49 are connected to the main line 11. The valve stem cavities 37, 49 and 36 are connected, to the main line 12. The valve cavity 36 and the rod cavities of the valves 44 and 48 are connected to the main line 13. The piston cavities of the valves 31, 34 through check valves 50, 52 and retaining valves 51, 53 are connected to the main 43, and their rod cavity is connected to the main 13 Piston polos valves 32 and 33 are connected to line 13, and their rod end cavities through electrically controlled stop valves 54 and 55 to line 43. Main line 12 is equipped with a safety valve 56, a check valve 57 and an electrically controlled stop valve 58, line 13 is safety valves 59, 60, and electrically controlled shut-off valve 61, and line 10 - electrically controlled shut-off valve 62. The device operates as follows. Downhole d 1 on the cable 14 is lowered with a winch into the well-to the studied horizon. Valve 34 is open and line 30 from cavity 29 to valve 31 is under hydrostatic pressure of a wellbore fluid. The pump 8 and valve are turned on. 58, 61 and 62 are supplied with the supply of working fluid under pressure to the line 12, and the connection of the line 13 to the line 10. The hydraulic cylinders 20 - 23 vibrate and protrude the borehole hole 1 in the well, the probe 28 of the sampler 19 enters the valve piston 36 rises, then the pressure in the line 12 increases, valve 49 opens and connects the cavity 27 of the sampler 19 to the pipeline 13, causing the probe rod 28 to retract and the well fluid flushes it 29. By When the rod 28 reaches its extreme position, the pressure in line 12 increases and valve 37. opens, causing valve 34 to close, stopping the borehole fluid from accessing line 30, and valve 31 opening relic liquid — from a portion of the borehole wall insulated by the sampler, enters line 30, as seen from pressure in line 30, which is measured by a pressure sensor. From console 1, a command is issued to switch valve 54, which passes the working fluid from line 43 to the rod cavity of valve 32, it opens, and the relic fluid enters tank 17. If necessary, tank 18 is also filled. To lift the wellbore to the surface or moving it to another horizon, the pump 8 is turned on, and the valves 61 to 62 supply the working fluid under pressure to the line 13, and the line 12 is blocked by the valve 58. The working fluid entering the rod cavity of the valve 44 opens it About, together, the line 43 with the line 10, after which the valve 37 is closed, maintaining in the line 12 a pressure sufficient to maintain contact with the walls of the well by the cylinders 20 - 23. The valve 32 is closed and locks the capacitor 17. By switching the safety valves 59 and 60, the pressure in line 13, and valve 34 opens. With a further increase in pressure, valve 48 opens and hydraulic cylinders 20-23 and existing sampler 19 return to their original position. With a further increase in pressure, valve 58 passes the working fluid from line 13 to the piston cavity of valve 31, and it closes.
    The sequence of actuation of the valves depending on the pressure developed by the pump is ensured by the selection of their springs. Thus, it is possible to take several samples without removing the wellbore from the well and monitor its operation.
