Detection device and operation tool and workover rig comprising same

Abstract

The utility model provides a detection device, an operation tool for an oil pumping pipe or an oil pumping rod and a workover rig. The detection device is used for detecting a coupling of an oil pumping pipe or an oil pumping rod, the detection device comprises two opposite clamping parts (1), two bias devices (2) and a sensor (3), wherein the two opposite clamping parts (1) are suitable for clamping the oil pumping pipe or the oil pumping rod from the two sides of the oil pumping pipe or the oil pumping rod; the two bias pressure devices act on the two clamping components (1) respectively so as to bias pressure the two clamping components (1) in the direction towards the oil pumping pipe or the oil pumping rod; and the sensor (3) is used for detecting the displacement of at least one clamping part (1) in the radial direction of the oil pumping pipe or the oil pumping rod so as to detect whether the clamping part reaches the coupling position or not. The detection device automatically realizes position detection of the coupling of the oil pumping pipe or the oil pumping rod in an accurate and reliable manner. The detection device can cooperate with other devices of the workover rig, and whole-course automation of the workover rig can be achieved conveniently.

Description

technical field [0001] The invention relates to the technical field of workover rigs, in particular to a detection device for detecting a coupling of a sucker pipe or a sucker rod, an operating tool including the same, and a workover rig. Background technique [0002] Existing workover rigs are usually manually operated during the operation of pulling out and lowering the oil sucker pipe and / or sucker rod. For example, in the process of pulling out the oil sucker / sucker rod from the downhole, it is necessary to disconnect the newly pulled out oil sucker / sucker rod from the downhole oil sucker / sucker rod to remove the oil sucker / sucker rod , this process is realized by unscrewing the sucker pipe / rod from the coupling connecting two adjacent sucker pipes / rods, and this process is also called tripping. In the process of lowering the sucker pipe / sucker rod downhole, contrary to the above process, it is necessary to connect the sucker pipe / sucker rod on the uphole with a part of...

AI Technical Summary

Problems solved by technology

The above-mentioned process is carried out manually, and the working environment of the workover operation site is very harsh, frequent safety accidents due to fatigue or illegal operations, and the cost of manual work is increasing. Therefore, it is urgent to develop an automatic, accurate and reliable A device that can automatically identify the height position of the sucker pipe / sucker rod to replace manual work
