М., «Недра, 1968, с. 176-187. 63 3 the plunger 4 lives, in the scraper of the hydraulic idr 3. With the plunger m 4 a core gauge 8 is connected, hinged in the housing 1. Device: drill pipe or cable is lowered into the Borehole to the sampling interval. A. When the plunger 4 is turned on and circulating under the action of a pressure drop, the housing IPD extends / until it stops, into the wall of the well, compressing the spring 7. Without stopping the circulation, the device is moved along the wall of the well. In this case, the liquid jets emanating from the nozzles 5 cut a sample of prismatic section from the borehole wall. Samples are stored in a core receiver 8. After sampling, circulation is stopped, plunger 4 under the action of M spring return 7 returns to the inside of the borehole /, and the device is lifted to the surface. Apparatus of the Invention A device for taking rock samples from borehole walls, comprising a housing with a Pressure channel, an extension of the cutting element with intersecting cutting planes to form a sample of a prismatic section and an extension mechanism of the cutting element in the form of a hydraulic cylinder , the cavity of which communicates with the pressure channel, from which it is designed so that, in order to increase the efficiency of sampling, the cutting element is made in va-where the movable plunger with jetting nozzles and hydraulic and ducts connecting the nozzles to the cavity of the hydraulic cylinder of the extension mechanism.
