Gas well blowout automatic environmental protection combustion device

Abstract

The invention belongs to the field of gas well open flow devices, and particularly relates to an automatic environment-friendly combustion device for open flow of a gas well. The device comprises an oil-water-gas separation silencer, an automatic start-up burner, a tank body and a wind-shielding combustion chamber, wherein the oil-water-gas separation silencer is communicated with the well mouth; combustible gas separated from the oil-water-gas separation silencer flows into the automatic start-up burner through a pipeline for combustion treatment; the inner space of the tank body is separated into three chambers, and a slurry pump, a water draining pump and an oil draining pump are correspondingly arranged in the three chambers; the oil-water-gas separation silencer is arranged above a mud discharge tank; the automatic start-up burner is arranged at the tail end of the oil-water-gas separation silencer and is connected with the oil-water-gas separation silencer; water separated from the oil-water-gas separation silencer flows into the mud discharge tank through a water seal isolation device; oil separated from the oil-water-gas separation silencer flows into an oil draining tank through an oil seal isolation device. The automatic environment-friendly combustion device can be used for reducing adverse impact of wind, rain and snow on the combusting process, so that sufficient combustion of combustible gas can be guaranteed.

Description

technical field [0001] The invention belongs to the field of blowout devices for gas wells, in particular to an automatic environment-friendly combustion device for blowout in gas wells. Background technique [0002] During the development of oil and gas wells or natural gas wells, it is necessary to carry out blowout tests on gas wells after drilling and completion or fracturing operations to determine the production capacity of gas wells and arrange production methods reasonably. A large amount of three-phase mixture of oil, water and gas will be produced during the spraying process. The oil and water in the mixture will be separated and transported away by tank trucks for separation treatment. Most of the gas in the mixture is combustible gas, which will pollute the atmosphere after being released. , so it needs to be incinerated by a combustion device. [0003] Most of the existing combustion devices are simple torch-type structures, which have the following defects: 1....

AI Technical Summary

Problems solved by technology

[0003] Most of the existing combustion devices are simple torch-type structures, which have the following defects: 1. The heat radiation to the ground is large, and there are light pollution, noise pollution, and the simultaneous combustion of crude oil and natural gas will cause pollution to the environment, etc., affecting surrounding residents Normal life; 2. The combustion flame is easily affected by wind, rain, and snow, resulting in insufficient combustion of the gas. When the gas volume is unstable, it is easy to be blown out by the wind, and the gas is directly discharged into the atmosphere, causing environmental pollution.
