Description

(54) ANCHOR DEVICE

one

The invention relates to the mining technique, namely to the root devices for fixing in the well bore an element of the bypass rope that is used to leave instruments, tools and other materials into horizontal and inclined wells.

A core device is known for fixing in the well bore an element of a bypass haul rope, made in the form of a wedging wooden block l

However, this device is unreliable in operation and, once installed in the well, is not removed back.

Closest to the invention in technical essence and the achieved result is a core device for securing in the well bore a bypass traction element comprising a hollow body rigidly connected to the bypass element, a spring and spacers 2j. A disadvantage of this device is the need for additional equipment to remove it from the well.

The purpose of the invention is to remove the core device from the well without

use of additional equipment.

This goal is achieved by the fact that the crust device — for fastening in the well bore — an element of the bypass traction rope, comprising a hollow body rigidly connected to the element of the bypass, a spring and expansion dies, is provided with

0 inside the housing and a spring connected to it, on which the spacer dies are hinged, which are located in the windows made in the housing.

FIG. 1 schematically shows a core device, a side view in FIG. 2 - the same, side view:

The anchor device contains a hollow body 1, rigidly connected to the element 2 of the bypass of the haul rope, spring 3, spreading dies 4 and the rod 5. Element 2 of the bypass is made in the form of an axis and provided with a cable roller 6. The rod 5 is located inside the body 1

5 and a spring 3 connected to it. The spacers 4 are hingedly mounted on the rod 5 and are located in the windows which are made in the housing 1.

A device with a 6th cable passed through a cable roller through an inclined or horizontal O well is pushed with drill pipes that abut the rod 5. At the same time, the spring 3 is compressed and the spacer plates 4 are retracted to prevent the device from moving. When the device reaches a predetermined depth, it is stopped to push, with the result that the spacer plates 4 under the action of the spring 3 expand and wedge the device body 1 in the well bore. Thus, the by-pass element 2, rigidly connected to the body 1, is securely fixed in the wellbore. Bypass traction cable, instruments, tools or other materials are delivered to the well. After the necessary work has been done, the instrument or tool is pressed against the rod 5 by tensioning the pull rope and creating a load. Under the action of this load, the spring 3 is compressed, and the spacer plates 4 are heated, not preventing the extraction of the crustal device and the bad. vym rope.

Application of the proposed root device. Allow to extract. it from the well quickly and without the use of additional equipment, which will significantly reduce the cost of money and time to conduct research in horizontal and inclined wells.
