Abstract

The invention relates to the drilling of oil and gas wells, namely, devices that can be used for drilling and securing shafts in the construction of multilateral wells and the drilling of additional wells. The purpose of the invention is to improve the reliability of work and the accuracy of the orientation of the diverter. The device consists of a housing 1 with an axial cylindrical channel 2, a piston 3, a fixing unit. The latter is made in the form of a sleeve 6 installed in channel 2 with a radial hole 7 located in the cavity of the sleeve 6 of the piston 3 and the retainer 9 installed in the hole 7. The rod 8 has a groove inclined toward the piston 3, and the retainer 9 is located in the latter. The deflector 5 is fixed in the housing 1 with the latch 9. After the deflector 5 is oriented, the flushing fluid is supplied to the cavity of the drill pipe. In this case, the piston 3 is displaced downwards, and the retainer 9 is displaced to the axis of the device, with the deflector 5 being released. 1 il.

The invention relates to the drilling of oil and gas wells, namely, devices that can be used for drilling and securing shafts during the construction of multilateral wells and drilling additional wells that have been in operation.

The purpose of the invention is to improve the reliability of work and the accuracy of the orientation of the diverter.

The drawing schematically shows a device for the installation of a diverter

A device for installing a diverter from the housing 1 with an axial cylindrical channel 2 for the passage of flushing fluid located in the channel 2 of the piston 3 of the fixing unit.

At the top of the piston 3 there are

-e

tongue projections 4 to orient the deflector 5, for example, Shangina-Kuligina. The fixing unit is made in the form of a channel 2 of the sleeve 1 of the sleeve 6 coaxially installed in the piston cavity of the sleeve 1 with a radial hole 7, the sleeve 6 located in the cavity and rigidly connected with the piston 3 of the rod 8 and the lock 9 installed in the sleeve 7 radial 7. 8, on the sides of the retainer 9, has a piston 3 that is inclined in the sides and has a 1-groove groove, which can be extended in section in the form of a dovetail. The latch 9 is mounted in the longitudinal groove with the possibility of movement. In the digger 5, a hole 10 is made under the clamp 9. Under the rod 8 a spring 1 is installed

The operation of the device is as follows.

Preparation of the device for launching into the well is carried out as follows. By pressing on the piston 3, which is fixed on the rod 8, the piston 3 is moved and the bolt 8 is in the lower position, while the clamp 9 moves to the axis of the housing 1, i.e. is installed in the sleeve 6. After that, the diverter 5 is inserted into the housing 1 until it stops. The force is removed from the piston 3. In this case, the rod 8 moves upwards under the action of the spring 1, thereby pushing the retainer 9, which, in turn, enters the P opening 10 of the opening 5. The device is ready to be lowered into the well.

When targeting a diverter 5

its position is determined by, for example, a Shalgin-Kulngin apparatus. The prints of the instrument's print from the jagged protrusions 4 determine the position of the diverter 5 relative to the oxide plane of the wellbore. The diverter 5 is placed in the required position and the device is disconnected from the diverter 5. To do this, into the cavity of the drill pipe

(not shown) serves washing fluid.

 In this case, the piston 3, compressing the spring 11, will move in the channel 2 of the housing

1 to the lowest position. The latch 9 when interacting with the longitudinal groove of the rod 8 moves in the radial hole 7 of the sleeve 6 to the axis of the device and exits the hole 10

reject 5.

The device is raised above the diverter 5. A decrease in pressure of the washing liquid will indicate the completion of the installation process of the diverter.
