Oil-gas mixed transportation integrated device not prone to blockage

Abstract

The invention relates to the field of oil-gas mixed transportation, in particular to an oil-gas mixed transportation integrated device not prone to blockage, which comprises a prying frame welding main body, an oil outlet and inlet pipeline and an oil outlet pipeline, the oil outlet and inlet pipeline and the oil outlet pipeline are mounted on the prying frame welding main body, and a first high-pressure electric valve is connected between the oil outlet pipeline and the oil inlet pipeline; the right end of the oil outlet pipeline is also connected with a first high-pressure electric valve and is sequentially connected with a safety valve and an output pipeline; the right end of the oil inlet pipeline is also connected with a first high-pressure electric valve, and is sequentially connected with a filter group and a shunt pipe; at least one oil-gas multiphase pump set is connected between the output pipeline and the flow dividing pipe, and the filtering set comprises a filtering structure and a cleaning structure. According to the invention, complicated pipelines are reduced, and meanwhile, the automatic cleaning mechanism is arranged, so that automatic cleaning can be realized under the non-stop condition, and therefore, blockage is not easy to occur.

Description

technical field

[0001] The invention relates to the field of mixed transportation of oil and gas, in particular to an integrated device for mixed transportation of oil and gas that is not easily blocked. Background technique

[0002] Oil and gas mixed transportation technology has developed rapidly in recent years. It is a new technology that directly transports crude oil output to the combined station through mixed pressurization. Compared with traditional oil recovery technology, it can reduce oil and gas separation equipment and build one less line. Gas pipelines can reduce the platform area for offshore oil fields. Oil and gas mixed transportation technology can greatly reduce engineering investment. It is of great significance for the realization of fully enclosed oil and gas gathering and transportation in oil fields, the complete recovery of casing gas and associated gas, and the extension of the radius of gathering and transportation. At the same time, it can reduce ...
