Description

Technical Field

[0001] The utility model relates to the technical field of correction tools, in particular to an oil field pipeline correction tool. Background Art

[0002] Oilfield pipelines are key infrastructure for oil and gas field exploitation and gathering. They are pipeline networks that transport oil and gas from underground reservoirs to processing plants or storage facilities. These pipelines play a vital role in the development of the oil and gas industry. After searching, the Chinese patent authorization number CN220837308U discloses an oilfield pipeline correction tool, which belongs to the technical field of correction tools, including: a base, a tubing bearing seat is arranged on the base, a linear motion device is arranged on the base, a longitudinal correction device is arranged on the linear motion device, a transverse correction device is arranged on the base, and the transverse correction device is arranged coaxially with the tubing bearing seat. The oilfield pipeline correction tool can effectively prevent secondary deformation of the pipe mouth due to over-correction when correcting the pipe mouth of the pipeline by means of the first limit block and the second limit block, and can correct the pipe mouth of the oilfield pipeline in the horizontal and longitudinal directions simultaneously by means of the longitudinal correction device and the transverse correction device, thereby ensuring the correction effect and solving the problem that the general oilfield pipeline correction device often fails to correct properly or over-corrects during correction.

[0003] The oilfield pipeline correction tool in the above patent has the following shortcomings: starting the second pressure cylinder and the third pressure cylinder drives the first horizontal correction block and the second horizontal correction block to squeeze and correct the pipe openings at both ends of the oil pipe to be corrected, thereby realizing lateral correction of the pipe. However, when the pipe opening is concave to a large extent, this correction method may make it difficult to correct the concave part of the pipe opening, thereby hindering the correction and making it difficult to ensure the correction quality. Therefore, an oilfield pipeline correction tool is provided. Utility Model Content
