Description

technical field [0001] The invention belongs to the technical field of petroleum machinery, and in particular relates to a remote fast grabbing device for a drilling tool check valve and a tubing cock valve for drilling and workover. Background technique [0002] Existing oil well, gas well are in the operation of drilling, workover, and when downhole pressure is too high, in order to prevent blowout, in order to guarantee personal, equipment safety, must screw on drilling tool with check valve, or screw on oil pipe with cock valve. [0003] Screwing up the drilling tool with the check valve, or screwing up the oil pipe with the plug valve is a very important work link. Its reasonable design can improve the work efficiency of drilling and workover and ensure the quality of drilling and workover. It is unreasonable to manually hold or lift the check valve and plug valve, run to the wellhead, and manually turn the buckle with both hands or manual operation of the pipe wrench: ...
