Problems solved by technology

[0005] At present, in some oil fields in my country, a considerable part of the oil wells are located next to the road, and there is a problem that there is no way to pull the guyline on the side of the road. There are also some oil wells in residential areas, which cannot be operated at night because of the noise problem, and the smoke emitted by the power machine also affects the health of residents.

Embodiment Construction

[0019] All equipment is installed on the base 4 of the energy-saving and emission-reducing petroleum workover rig. The rear portion is arranged with a folding retractable drill floor 11, a cantilever vertical telescopic derrick 15, and a large hydraulic motor 9. The drum 7 is arranged in the middle, the pump-oil motor 19, the gearbox 6, the control room 5, and the electric air compressor 33. Power distribution cabinet 35 is arranged at the front, large motor-oil pump group 34, small motor-oil pump group 31, cooler 32, fuel tank 1, energy storage cylinder 2, and gas tank 3. There is a hydraulic jack 12 on both sides of the rear part of the base 4, and a hydraulic jack 12 is respectively arranged on both sides of the middle front part. Cantilever vertically telescopic derrick 15 is raised and connected with bolts one by one by derrick telescopic lifting oil cylinder 10, and is put down one by one after the operation is completed. Folding and retractable drilling platform 11 is...

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...
