Embodiment 1

[0024] Example 1, such as Figure 1 to Figure 3 As shown, this embodiment provides a liquid bubble atomization method for gas well stimulation. The production of formation water is often accompanied by the production of formation water, which accumulates at the bottom of the well, affecting the gas in the formation from entering the bottom of the well and reaching the ground through the wellbore. , when the production of the gas well is low, the effusion flows back along the wall of the wellbore, making it difficult to discharge the wellbore, and accumulates at the bottom of the wellbore to hinder the production of gas. Usually, it is through gas lift, foam row, throwing foam rods, replacing small-diameter tubing, etc. Although these methods can remove fluid accumulation and increase the production of gas wells, artificial lifting and continuous input of chemical agents will not only increase production costs but also cause some pollution to the environment. The specific meth...

Abstract

The invention belongs to the technical field of natural gas or coal gas production, and relates to a liquid bubble atomization method for gas well stimulation. Multiple liquid accumulation atomization devices are installed in the wellbore to realize the joint use of multiple liquid accumulation atomization devices, and multiple liquid accumulation atomization devices are used in combination to form a functional group, and the bottom of the well is gradually foamed or foamed. Atomization, so as to discharge the bottom-hole fluid out of the wellbore; use the airflow power relay to move the liquid up step by step, and limit the backflow of the liquid through the edge of the atomization device to improve the efficiency of fluid removal. The device body includes an oil pipe and an orifice plate arranged inside the oil pipe. The orifice plate is made of metal or non-metal material, and the orifice plate is provided with circular or polygonal through holes. It can not only effectively overcome the backflow of effusion, but also reduce the amount of chemical agents, save costs, and improve the effective time of measures, and can be widely used in the mining process of natural gas and coalbed methane.

Description

technical field [0001] The invention belongs to the technical field of natural gas or coal gas production, and relates to a liquid bubble atomization method for gas well stimulation. Background technique [0002] The production of formation water is often accompanied by the production of formation water, which accumulates at the bottom of the well, affecting the gas in the formation from entering the bottom of the well and reaching the ground through the wellbore. , when the production of the gas well is low, the effusion flows back along the wall of the wellbore, making it difficult to discharge the wellbore, and accumulates at the bottom of the wellbore to hinder the production of gas. Usually, it is through gas lift, foam row, throwing foam rods, replacing small-diameter tubing, etc. Eliminate fluid accumulation and increase gas well production. Although these methods can better eliminate fluid accumulation, artificial lifting and continuous input of chemical agents will ...
