Abstract

The invention discloses a method and system for uplifting and lowering an oil pipe, and belongs to the field of petroleum machines. The system comprises an electric control hydraulic station, a supporting base, a mechanical arm, a push-pull mechanical arm, an oil pipe lift sub, a lifting ring, an oil pipe clamp, an oil pipe clamp in-position device, a remote oil pipe clamp control device and an oil pipe chuck. The method and system solve the problem that during oil pipe uplifting and lowering, safety is low, and the effect of improving the operation safety is achieved. The method and system are used for uplifting and lowering the oil pipe at a well mouth of an oil well and a well mouth of a water well.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a method and system for lifting and lowering oil pipes. Background technique [0002] Workover operation is an important means to maintain the normal production of oil and water wells in the process of oilfield development. In the daily workover operation, the oil pipe needs to be pulled out or run in frequently, and the workload of lifting and lowering the oil pipe is very large. [0003] In the prior art, at least 4 operators are required to form a work team when lifting and lowering the tubing at the workover site, among them, one operator is the driver of the workover rig, standing on the workover rig and controlling the workover rig to complete the hook Moving up and down, coordinating work progress and monitoring work, etc.; one operator stands on the well site to pull the tubing, pulls the unloaded tubing to the tubing bridge when pulling up the tubing, and moves one en...
