Problems solved by technology

This work alone consumes a lot of manpower, material resources, and time to straighten and align misplaced pipelines, which poses a high safety risk and does not meet the needs of the site
[0004] To sum up, the main problems existing in the existing artificial righting pipelines are: (1) The site conditions are harsh, and the ground foundation is not stable, which may easily cause the jack to drive the force point to be unstable and lose its due effect; (2) It requires many workers and labor intensity Large, at least 6-8 people; (3) It takes a long time, up to 4 hours, resulting in reduced working time, thereby affecting the production of oil wells; (4) The force of a large number of people and the cooperation of various machines are carried out at the same time. It is easy to cause personal injury during work; (5) It is easy to cause pipeline deformation and damage during mechanical correction; (6) The success rate of manual pipeline correction and installation is low, and it is easy to cause rework

Abstract

The invention discloses a pipeline strengthening and centering device which is used for maintaining oil well pipelines. The pipeline strengthening and centering device comprises a guide device, a first pipeline locking device and a second pipeline locking device. The first pipeline locking device and the second pipeline locking device are arranged in the guide device, and are buckled at two ends of a to-be-maintained pipeline. The distance between the first pipeline locking device and the second pipeline locking device on the guide device can be changed. With the pipeline strengthening and centering device, number of on-site operating workers in the process of oil fieldpipeline maintenance can be reduced, operating time can be saved and working efficiency can be improved.

Description

technical field [0001] The invention relates to a pipeline centralizer, in particular to a pipeline centralizer used in the maintenance process of oil field pipelines. Background technique [0002] With the increase of the scale of oilfield development and the substantial increase of various process pipelines, the medium causes corrosion and damage to pipelines and valves, resulting in increasing problems such as fracture, disconnection, leakage repair, lameness, and deformation of various pipelines. The workload of maintenance has increased significantly. When dealing with such problems, there is no suitable time-saving and labor-saving tool in domestic oil fields at present. The manual straightening pipeline method is widely used now, but it has defects and problems such as low working time, high labor intensity, high safety risk, and easy to cause personal injury, which seriously affects the normal production of oil wells and reduces the production timeliness of oil well...
