Abstract

The invention discloses an energy-saving and emission-reducing petroleum well servicing rig, which is driven by electricity. Based on a hydraulic energy storage principle, corresponding hydraulic stations and corresponding action elements are started according to different hook loads, so that the whole machine has a low installed power and total operational energy consumption which is only one quarter of that of a conventional well servicing rig, thereby saving a large amount of energy. The well servicing rig is convenient in transfer and installation due to an arranged cantilever vertically telescope derrick and an arranged folded retractable drill stand and is low in labor intensity and good in economic benefit.

Description

technical field

[0001] The invention belongs to a petroleum workover rig Background technique

[0002] At present, most oil workover rigs are powered by diesel engines with large installed power. During operation, there is a lot of noise and a lot of smoke exhaust, especially when the load is heavy, the accelerator must be increased to provide power.

[0003] The oil workover process is a process in which oil pipes and tools are raised first, the wells and tools are repaired, and then the corresponding equipment and oil pipes are lowered. Thousands of meters of tubing weigh tens of tons, which requires the workover rig to be powered according to the maximum load. But when lifting the oil pipe, it starts to be heavy, and as the oil pipe is raised one by one, the weight continues to decrease, and the process of lowering the oil pipe is light at first and then heavy. In the process of lifting and lowering the oil pipes, it is discontinuous, and it is necessary to break out o...
