Description

Technical Field

[0001] The utility model relates to the technical field of petroleum equipment, in particular to a structure for reducing the overturning moment of a self-tensioning derrick. Background Art

[0002] As an important equipment for oilfield workover operations, workover rigs play an important role in the field of oilfield workover operations at home and abroad. As the oil and gas industry has higher and higher requirements for high efficiency and low cost in well workover operations, the field of well workover operations is now more and more inclined to self-tensioning rope workover rigs, especially in foreign markets. Some large oil and gas development companies in the Middle East require self-tensioning rope workover rigs when bidding. However, for workover rigs with large hook loads, stability is the key to ensuring the normal operation of the workover rig. Solving the overturning problem during operation is an important factor restricting the development of self-tensioning rope workover rigs. The overturning line distance of existing self-tensioning rope workover rigs is long, and the overturning moment generated is large, which can easily affect the stability of the workover rig.

[0003] Therefore, it is necessary to propose a technology to improve the above defects. Utility Model Content
