Sinopec News Network (Wang Jinfa, Yuan Qixin) The hydraulic clamp anti-misoperation protection device designed by Cui Wanyong and Yang Yuwen, employees of Shengli Oilfield Downhole Operation Company, recently won the* * patent. During well workover, oil testing operations, and the process of lifting oil pipes and drill pipes, the oil pipes and drill pipes need to be buckled or unfastened using hydraulic tongs to complete the connection of the pipe strings into the well and out of the well. During the construction process, the hydraulic tongs need to be reversed and replaced to complete the specific construction. Therefore, it is easy to cause accidents caused by misoperation and injury to the hydraulic tongs. The anti-misoperation protection device of hydraulic tongs can effectively prevent accidental operation of the hydraulic tong operating rod from being hit during oilfield construction, and fundamentally overcomes the shortcomings of the existing protective devices of hydraulic tongs. This new patented structure has a simple structure, can lock and unlock the operating rod of the hydraulic clamp quickly and conveniently, and is low-cost. It has been promoted and implemented by underground operating companies and has a remarkable safety protection effect.
