Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, the present invention includes: the hydraulic system comprises a hydraulic oil tank 1, a hydraulic pump 2 connected with the hydraulic oil tank 1, a hydraulic valve 5 connected with the hydraulic pump 2 through a hydraulic pipeline 4, a hydraulic cylinder 6 and a pressure gauge 7;
wherein the content of the first and second substances,
the output end of the hydraulic pump 2 is also provided with a control valve (an overflow valve 3 in the embodiment) through a hydraulic pipeline 4;
the hydraulic cylinder 6 is also connected with a downhole special tool 8;
the downhole tool 8 is of a tubular construction and the downhole tool 8 is of a variety of specific sizes within the size range of the safety slips 9 application.
Arranging a safety slip body 9 arranged on the periphery of a downhole tool 8; the hydraulic rod of the hydraulic cylinder 6 is controlled to contract, the downhole tool 8 is controlled, and the safety slip body 9 on the periphery of the downhole tool 8 is pressed tightly, so that the downhole tool 8 is clamped.
The safety slip body 9 has a plurality of (5 in this embodiment) elliptical structures installed around the downhole tool 8, and a plurality of circular holes (two in this embodiment) for connecting with the well are formed on the elliptical structures.
When the hydraulic clamping tool is used, the hydraulic pump 2 is started, when the hydraulic valve 5 is in the right position, high-pressure hydraulic oil enters the right cavity of the hydraulic cylinder 6, and a hydraulic rod of the hydraulic cylinder 6 contracts, so that a conventional safety slip body 9 arranged on the periphery of the tool 8 is pressed tightly, and the downhole tool 8 is clamped;
when the hydraulic valve 5 is in the middle position, high-pressure hydraulic oil flows back to the hydraulic oil tank 1; when the hydraulic valve 5 is in a left position, high-pressure hydraulic oil flows into a left cavity of the hydraulic cylinder 6, the hydraulic rod extends out, the conventional safety slip body 9 is loosened, and the downhole tool 8 is loosened; meanwhile, no matter where the hydraulic valve 5 is, as long as the oil pressure of the hydraulic oil exceeds a pressure set value, the high-pressure hydraulic oil flows back into the hydraulic oil tank 1 from the overflow valve 3; because the hydraulic cylinder 6 is provided with the pressure gauge 7, the clamping force of the safety slip body 9 on the downhole tool 8 can be accurately known, and the problem that the downhole tool 8 is damaged due to the fact that the clamping force is too small and cannot be safely acted or too large is solved.
