  • the technical object of the invention is to create a easy to use, simple and reliable device a wide range of applications.
  • the device according to the invention hydromechanical generation of slots in borehole walls solved, which is a housing, an extendable cutting tool in the form of a roller, a hydraulic monitor attachment and an oblique to the longitudinal axis of the device arranged wedge bounded laterally by removable boundary plates has, wherein the axis of the roller is designed stepped and at its ends has a small diameter, and in parallel to that through the Boundary plates and the keyway formed guide grooves is led.
  • the device has a hollow rod filter (with cross holes provided tube arranged along the longitudinal axis of the device) is provided, which (coaxial) in two sealed against each other Hydraulic cylinders is housed, the lower hydraulic cylinder with a spring-loaded piston rod is connected, which is a central, along the Longitudinal axis of the device running rinsing channel as a main and a parallel Auxiliary hydraulic duct running offset to the longitudinal axis of the device has, and is connected via two profile plates to the roller, which the Removable boundary plates arranged on both sides of the wedge (front) touch, the wedge removable and when operating the roller opposite the Borehole wall is slidably arranged, the ends of the roller axis in in the side plates arranged guide grooves are guided, and the Side plates the roller and the profile plates arranged on both sides of the roller include, also the device with a shear circulation valve (Ball valve seat) and a hydraulic monitor (water cannon, nozzle) is on arranged
  • the device according to the invention is in its initial position, in Figure 2 shown in cross section A-A.
  • the device has a housing which consists of four parts is composed: Pos. 1, 2, 3, 4.
  • the upper hydraulic cylinder 1 in which the spring-loaded hollow rod filter (tube provided with transverse bores) 6 with the piston 7 is arranged, the upper hydraulic cylinder 1 is connected to the lower hydraulic cylinder 2, which with the medium divider (Diaphragm) 8 is provided and supports the spring 5, which lies on the hollow rod filter (tube with cross bores) 6 in the upper hydraulic cylinder 1 and which seals the upper and lower hydraulic cylinders and the hollow rod filter (tube with cross bores) 6 against each other.
  • the lower end of the hollow rod filter (tube provided with transverse bores) 6 is connected to the piston rod 9 via the fastening 10, in which a seat for a ball valve is arranged, which is arranged above a central flushing channel 11 arranged in the piston rod 9.
  • the upper part of the piston rod 9 (piston) has a circular cross section and a device for fastening the lower end of the spring 12.
  • the upper end of the spring 5 is attached to the device 13, which is located in the upper part of the hydraulic cylinder 2 under the medium divider (diaphragm) 8.
  • Two hydraulic channels are arranged in the piston rod 9: a central flushing channel 11 having a drain opening 12 and a secondary channel 14, at the lower end of which a hydraulic monitor attachment 15, in particular a water cannon or a nozzle, is arranged.
  • a profile plate 19 is arranged, which is connected to a roller axis 20 arranged transversely to the longitudinal axis of the device and via this and via two removable side plates 25 are in contact with a keyway 26 which runs obliquely to the longitudinal axis of the device and which is arranged on the lower part 18 of the housing 3.
  • a gap for receiving the roller 23 is formed in the housing 3.
  • the ends of the roller axis 20 which have the smaller diameter are guided in the guide grooves 24 which run parallel to the direction of the removable keyway 26, the profile plates 19 being arranged between the roller 23 and the side plates.

  • a ball valve seat 29 is arranged, the housing 4 of which is connected to the upper hydraulic cylinder 1, the ball valve seat 29 being held by shear pins which are arranged in a fastening 30.
  • the housing 4 of the ball valve seat 29 is a threaded transition piece, which is used for receiving drill or pump and compressor pipes (PKR) which are led through the borehole to the device.
  • PTR drill or pump and compressor pipes
  • the device works as follows:
  • the device on the strand of PKR is lowered to the perforation site. After Positioning the device in the borehole is followed by a flushing of the Device and the borehole in the area of the device to scale, and mechanical particles, especially sediment and deposits of Boulders that are used in geophysical work, especially in the Advancing the borehole and performing any work that may be required to adjust the borehole to insert the device into the borehole and got into the cavities and pipes of the device remove.
  • the overpressure in the Liquid acts on the piston 7 and at the same time through the holes in Hollow rod filter (tube with cross holes) 6 on the cavity in the Housing 2. This moves the piston 7 and piston rod 9 forward while simultaneously expanding the spring 12 and compressing the spring 5.
  • the piston rod 9 presses in the direction of the forward movement Longitudinal axis of the device via the axis 17 on the between the profile plates 19 arranged roller 23 and steers this due to the bilateral storage of the Ends of the roller axis 20 in the parallel to the keyway 26 and obliquely to Guide grooves 24 of the side plates 21 running along the longitudinal axis of the device out.
  • the pressure in the Device After the gap in the borehole wall has been rolled out, the pressure in the Device further increased so that from the hydro monitor attachment (water cannon, Nozzle) 15 a liquid jet emerges.
  • the liquid jet emerges from the Hydromonitor attachment (water cannon, nozzle) 15 at high speed and with his pressure destroys the cement stone and the rock behind the Borehole wall and rinses a cavern over the entire gap length.
  • the distance between the hydro monitor attachment (water cannon, Nozzle) 15 and the roller axis 20 constant. After rinsing the cavern the pressure in the device is reduced to ambient pressure.
  • the piston rod 9 is drawn into the housing 2 and brings the entire cutting assembly back into the starting position.
  • a second ball with a larger diameter is then lowered through the PKR strand to the device which closes the ball valve seat 29.
  • the pressure of the ball on the ball valve seat 29 shears off the shear pins arranged in the fastening 30, which serve to fasten the ball valve seat 29 in the direction of the longitudinal axis of the device, so that after the ball valve seat 29 has been sheared downwards falls and releases a flushing device in the housing.
  • the borehole is then started up or pumped empty, or the device is recovered therefrom.
  • the device was tested in the development of new sources. The stake the device reduces the costs of commissioning boreholes.
