Problems solved by technology

During the large-scale development and injection process of natural gas in the central and western regions of the West-East Gas Transmission Project in the past ten years, natural gas has not been recovered, resulting in a huge waste of resources
[0004] Chinese patent CN201520561980.2, published on December 23, 2015, the name of the invention is "an oil and gas field blowout combustion tank device". The pollution to the environment during the combustion of the medium blowout, the shortcoming is that the blown natural gas cannot be recovered
[0005] Chinese patent CN201520843783.X, published on February 24, 2016, the name of the invention is "Natural Gas Well Initial Release Gas Recovery Device", the patent discloses a natural gas recovery device for the initial release of natural gas well development, the disadvantages are The discharge fluid is not diverted, the gas-liquid-solid impact force at the discharge liquid inlet is large, and it is easy to cause damage to the container, and the discharge fluid enters the container with mist objects, the equipment does not deal with it, and the pressure of the natural gas itself is required to drive the liquid into the oil and water The separator increases the resistance to blowout and affects the blowout effect of natural gas wells. Another shortcoming of this invention is that there is no drainage recovery device
[0006] Chinese patent CN201410691896.2, published on November 25, 2014, the name of the invention is "skid-mounted vent gas recovery system and recovery method", which discloses a natural gas well exploitation vent gas recovery system and recovery method. The disadvantage is that the first-level and second-level sand removal equipment in the device will produce resistance to the flow of blowout and flowback fluid during operation, which will affect the blowout effect and have adverse effects on the later production of natural gas wells

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...

Abstract

The invention discloses a discharging-assisted yield-increasing blowout liquid discharging natural gas recovery device and method and is suitable for sand removing, liquid removing and recovery of natural gas during fracturing blowout at the early stage and in the process of oil and natural gas extraction. The recovery device is composed of a diversion blowout device 1, a sedimentation high-pressure recovery container 2, an external force discharging-assisted recovery device 3 and a liquid discharging device 4, a diversion blowout device valve I 6 is connected with a natural gas blowout port 5, a pipeline in rear of the valve I forms four blowout ports through diversion and then enters the sedimentation high-pressure recovery container from four high-pressure container diversion inlets 11 at the left end of the high-pressure container, a sand discharging port 32 is arranged at the bottom of the left end of the sedimentation high-pressure recovery container, a liquid discharging port 25 is arranged at the bottom of the right end of the sedimentation high-pressure recovery container, a high-pressure container natural gas outlet 19 is arranged on the upper portion of the right end of the sedimentation high-pressure recovery container and connected with the external force discharging-assisted recovery device 3, the liquid discharging port is externally connected with the liquid discharging device 4, and the sand discharging port is provided with a valve V31.

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...
