Изобретение относитс к горному делу и предназначено дл измерени- с.мещений и деформаций горных пород в скважинах.The invention relates to mining and is intended to measure the displacements and deformations of rocks in wells.

Известен репер дл измерени смещений и деформаций горных пород в скважинах , включающий полый корпус, состав. штанг и распорнофиксирующий механизм, выполненный в виде черв ка 1.A known bench mark for measuring displacements and deformations of rocks in wells, including a hollow body, composition. rod and spacer mechanism, made in the form of a worm 1.

Однако устройства такого типа недостаточно прочно фиксируютс в скважинах .However, devices of this type are not firmly fixed in the wells.

Наиболее близким по технической сущности к изобретению вл етс устройство дл измерени смещений горных пород в скважинах, включающее упорные пластины с шинами и пружины, расположенные между пластинами. Корпус снабжен четырьм отверсти ми, в которые вход т подпружиненные между корпусом и упорными пластинами пальцы. Устройство доставл ютв место измерений в сжатом состо нии. При вращении щтанг щток выводит пластины из зацеплени со штифтами, после чего устройство под действием пружины и конусов, распирающих пальцы, закрепл етс в скважине 2.The closest in technical essence to the invention is a device for measuring displacements of rocks in wells, including thrust plates with tires and springs located between the plates. The housing is provided with four holes, into which the fingers are spring-loaded between the housing and the abutment plates. The device delivered the measurement site in a compressed state. When rotating, the shthang sweeper removes the plates from engagement with the pins, after which the device is fixed in the borehole 2 by the action of a spring and cones that gouge fingers.

Недостатками- данного устройства вл j ютс невозможность его извлечени из скважины дл повторного использовани , а также ограниченный объем получаемой информации , так как конструкци устройства 5 не позвол ет производить измере1 ие ncftieречной деформации скважины. .The disadvantages of this device are the impossibility of its removal from the well for reuse, as well as the limited amount of information obtained, since the design of the device 5 does not allow measuring the ncftierite deformation of the well. .

Цель изобретени - снижение затрат на измерени путем обеспечени возможности многоразового использовани устройства .The purpose of the invention is to reduce the cost of measurement by allowing the device to be reusable.

Указанна цель достигаетс тем, что устройство дл измерени смещений и де формаций горных пород в скважинах, включающее упорные пластины с шипами, пружины , расположенные между пластинами, 15 снабжено кронштейном с роликом, двум фиксаторами и двум гибкими нит ми, при этом кронштейн жестко закреплен на одной из упорных пластин, а фиксаторы - щарнирно на другой с возможностью взаимодействи с кронштейном, а гибкие нити закреплены на свободных концах фиксаторов , причем одна из них перекинута через ролик.This goal is achieved by the fact that the device for measuring displacements and deformations of rocks in wells, including thrust plates with spikes, springs located between the plates, 15 is equipped with a bracket with a roller, two clamps and two flexible threads, while the bracket is rigidly fixed to one of the stop plates, and the clamps are hinged on the other with the ability to interact with the bracket, and the flexible threads are attached to the free ends of the clamps, one of which is thrown over the roller.

Claims

The drawing shows an exemplary embodiment of the proposed device. Thrust plates 1 are made in the form of arcs with tires on the outside. On the inner side of the plate two springs 2 and two brackets 3 and 4 are fastened. Bracket 3 is hinged with clips 5 and 6, cables 6 and 8 are attached to the free ends. Cable 8 is thrown over roller 9, which is in bracket 4. For The device is delivered to the place of installation on one of the thrust plates fixed to the coupling 10. The device operates as follows by means of a frame 10 and is connected with a billet rod and the device is delivered to the measurement site in a compressed position. In this case, the latch 5 is engaged with the bracket 4, and the springs 2 are compressed. In the right place, holding the device with the rods, pull the cable 7, which disengages the retainer 5 with the bracket 4. The springs 2 press the thrust plates against the walls of the well and thus fix the device in the well. Becoming rod removed from the well. The free end of the cable 7 is tensioned and secured to a spring-loaded measuring device slider secured in a well bore (not shown). The cable 8 is tensioned with a force which is obviously less force of the spring 2, and is attached to the second spring-loaded DVILC of the measuring device. -. The longitudinal displacement of the device relative to the measuring device is measured with the cable 7, and the lateral deformation in the wells is expressed in the difference between the movements of the wires 7 and 8. To remove the devices from the well by pushing the device in the well and pulling the cable 8 . The springs 2 are compressed, and the latch 6 is engaged with the bracket 4. Pulling the cables 7 and 8, the device is removed from the well. The design of the proposed device is simple in execution and. allows measurements in wells of different diameters. Using clamps and a roller, it is possible to measure both longitudinal and transverse strains at the same time, and after completing measurements, remove the device from the well for repeated use. Apparatus of the invention for measuring mixes and deformations of rocks in wells, including thrust plates with tires and springs located between the plates, characterized in that, in order to reduce the cost of measurement by allowing the device to be reusable, it is equipped with a roller bracket, two clamps and two flexible threads, while the bracket is rigidly fixed. on one of the thrust plates, and clamps, - hinged on the other with the ability to interact with the bracket, and the flexible threads are attached to the free ends of the clamps, with one of them thrown over the roller.
