Gas collecting device of whole skid booster station

Abstract

The invention relates to a gas collecting device of a whole skid booster station. The gas collecting device of the whole skid booster station comprises a gas inlet separator, a booster device, an oil-gas separator, a gas-water separator and a metering valve bank, wherein the gas inlet separator, the booster device, the oil-gas separator, the gas-water separator and the metering valve bank are integrally arranged on a workstation in a pipeline connection mode; the gas inlet end of the gas inlet separator communicates with the gas inlet of the gas collecting device; the gas outlet end of the gasinlet separator communicates with the oil-gas separator through the booster device; the oil-gas separator communicates with the gas-water separator; the gas-water separator communicates with the metering valve bank; and the metering valve bank communicates with the gas outlet of the gas collecting device. The gas collecting device of the whole skid booster station has the beneficial effects thatthrough the integrated skid block design of station-entering separation, gas boosting and output metering, the gas collecting device in the integrated skid block design can replace a booster station so as to achieve a boosting effect. The gas collecting device of the whole skid booster station has the advantages of small occupied area, low investment cost and convenience and flexibility in installation.

Description

technical field [0001] The invention belongs to the technical field of coal bed gas collection equipment, and in particular relates to a gas collection device for a whole skid booster station. Background technique [0002] my country's coalbed methane resources are abundant, and the huge market has yet to be tapped. The mining and utilization of coalbed methane are strongly supported by national policies. Through the mining of coalbed methane, mine gas disasters and environmental pollution have been greatly reduced. The development and utilization of coalbed methane has multiple advantages. Efficacy: clean energy, commercialization can produce huge economic benefits, and it is a national strategic resource. There are generally two ways to mine coalbed methane: one is ground drilling and mining; the other is underground gas drainage system extraction. Both coalbed methane and drained gas mined by ground drilling can be used, and can be greatly improved after ground mining and ...

Problems solved by technology

[0004] The front-end pressurization is collected by the coalbed methane from each well site to the gas gathering station for centralized pressurization and transportation. The equipment of the gas gathering station mainly includes the in-station separation device, booster device, out-station metering device and auxiliary production equipment. Independent layout, large footprint, cumbersome construction, not flexible enough to move
