Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the skid-mounted blowout gas recovery system includes a blowout prevention pipeline 2, a primary sand removal device 3 and a secondary sand removal device 4, and the primary sand removal device 3 and the secondary sand removal device 4 are all set in on a removable chassis. The primary desander device 3 includes two parallel primary desanders, and the secondary desander device 4 includes two parallel secondary desanders. There is a tee I7 between the wellhead and the oil nozzle, and the pipeline leading from the production test wellhead is respectively connected to the blowout prevention pipeline 2 and the air inlet of the first-stage sand removal device 3 through the three-way I7, and the gas outlet of the first-stage sand removal device 3 is connected to the second The air inlet connection of stage desanding device 4. The air outl...

Abstract

The invention relates to a device for separating substance produced in a well, in particular to a skid mounted blowout gas recovery system and method. The skid mounted blowout gas recovery system comprises a blowout pipeline, a primary desanding device and a secondary desanding device, wherein the primary desanding device and the secondary desanding device are arranged on a movable chassis, a pipeline led out of a trial production well mouth is connected with the blowout pipeline and a gas inlet of the primary desanding device respectively through a tee joint I, a gas outlet of the primary desanding device is connected with a gas inlet of the secondary desanding device, a gas outlet of the secondary desanding device is connected with a gas inlet of a pressure regulating valve group, a gas outlet of the pressure regulating valve group is connected with a metering valve group, a tee joint II is arranged on the pipeline connected with the tee joint I and the primary desanding device, an outlet of the tee joint II is connected with the primary desanding device, and the other outlet of the tee joint II is directly connected with the pressure regulating valve group through a pipe. The skid mounted blowout gas recovery system is good in adaptability and wide in working range, natural gas processed and recovered by means of the system and method can be directly put into an outer net for usage, and the energy-saving and emission-reducing purposes can be achieved.

Description

technical field [0001] The invention relates to a device for separating substances produced in a well, in particular to a skid-mounted oil and gas well recovery system and recovery method for blowing gas during test production. Background technique [0002] At present, during the development and test production of my country's oil and gas fields, the natural gas produced by some scattered test wells cannot be used reasonably, and can only be disposed of by burning and venting. Taking the development test production in Wushen Banner area as an example, there are about 100 test production wells each year, and the natural gas volume of each well is about 50,000 to 100,000 cubic meters per day, and the test production period is about 10 days. The annual vented natural gas is about 50-100 million cubic meters. The burning and venting of a large amount of natural gas not only causes a waste of resources, but also causes serious environmental pollution. [0003] At present, durin...
