Description

Technical field

[0001] The present invention relates to the field of petroleum and natural gas exploitation, in particular, it is a device and method for recovering natural gas and flowback fluid during fracturing and blowout during the development of oil and gas fields, which is suitable for the initial stage of oil and gas exploitation and the fracturing and blowout during the exploitation process During the period, the sand removal, liquid removal and natural gas recovery operations of natural gas will be carried out. Background technique

[0002] With the increasing demand for natural gas resources in daily life, the public and the society pay more and more attention to environmental protection, which makes us not only pay attention to the efficient use of natural gas, but also pay attention to environmental protection in the process of natural gas utilization, but in the process of development Grounded, potentially, and long-term impact on human survival and development...

Embodiment Construction

[0018] Such as figure 1 As shown, the recovery device and method for aiding drainage and increasing production, venting and discharging liquid natural gas are composed of a split flow venting device 1, a subsidence high-pressure recovery container 2, an external force aided drainage recovery device 3 and a liquid discharge device 4, and the valve 16 of the split venting device is connected to the The natural gas well blowout opening 5 is connected, and the pipeline behind the valve 1 is divided into two, and the liquid when the natural gas well blowout is blown is carried out a shunt. A valve II 7 is set on each pipeline after the primary diversion to control each pipeline individually. A nozzle cover 8 is connected behind the valve II to control the flowback liquid volume when replacing the nozzle. The outlet pipeline of the nozzle sleeve simultaneously It is connected with valve III 9 and valve IV 10. Valve III 9 is used for pressure relief when replacing the nozzle, and val...
