An eccentric rotary swing compressor multiphase oil and gas mixing and conveying device

Abstract

The invention discloses a multi-phase oil-gas mixing conveying device of an eccentric rotating and swinging type compressor. Elastic sealing bodies are distributed on the outer wall of a swinging rotor sleeve in the circumferential direction in a spacing manner, so that the phenomenon of internal leakage of a high-pressure cavity and a low-pressure pipe is avoided; the difficulty that hybrid conveying of raw oil, natural gas, water and various sticky substances via a single pipeline is hard to implement is solved; no discharge and no pollution are caused in an oil well; the mechanical structure is simple, and the theory is correct; the multi-phase oil-gas mixing conveying device is easy to manufacture and maintain; at low operation speed, no noise and no pollution are caused; random variable operation can be implemented; and the multi-phase oil-gas mixing conveying device can be used in a severe environment for a long time.

Description

technical field [0001] The invention belongs to power machinery, in particular to an eccentric rotary swing compressor multi-phase oil-gas mixing conveying device. Background technique [0002] At present, in my country's petroleum industry, crude oil, natural gas, water, sediment, flocs and various viscous substances are difficult to achieve multi-phase mixed transportation in a single pipeline, resulting in a large number of repeated construction, repeated investment, and serious serious problems caused by casing gas emissions. Environmental pollution and waste of social resources. [0003] In order to solve the multi-phase mixed transportation of oil and natural gas production, improve asset utilization, reduce construction investment, realize oil well casing gas recovery, avoid air pollution, and save social resources, it is a technology in the field to find new multi-phase mixed transportation devices. One of the subjects of concern. [0004] Existing multiphase oil-ga...

Problems solved by technology

It is necessary to keep the rotor in close contact with the inner wall of the housing at any time, otherwise the medium between the high-pressure chamber and the low-pressure chamber may be exchanged before reaching the set position. For example, after the rotor is worn, the medium in the high-pressure chamber can pass through The gap between the rotor and the housing enters the low-pressure chamber, and the pressure cannot be adjusted accurately

[0005] In the prior art, it is theoretically feasible to separate different cavities only by the contact between the rotor and the inner wall of the housing, but this requires high machining accuracy for the inner wall of the housing and the shape of the rotor, which is difficult to achieve. ; and the rotor will inevitably wear out during use, which makes the existing multi-phase oil-gas mixing device generally suffer from a decline in accuracy after a period of use
