Effusion bubblization and atomization method used for gas well stimulation

Abstract

The invention belongs to the technical field of natural gas or coal gas production, and relates to an effusion bubblization and atomization method used for gas well stimulation. By means of installation of multiple effusion atomization devices in a shaft, combined utilization of the multiple effusion atomization devices is achieved, a way of a functional group is formed by combined utilization of the multiple effusion atomization devices, and step-by-step bubblization or atomization is conducted on effusion in the shaft bottom, so that the effusion in the shaft bottom is discharged from the shaft; by means of an airflow dynamic relay mode, the effusion is shafted up step by step, and through edge portions of the atomization devices, backflow of the effusion is limited, so that the discharging efficiency of the effusion is improved. A device body comprises an oil pipe and at least one pore plate arranged in the oil pipe, the pore plate is made of metal or nonmetal material, and circular or polygonal through holes are formed in the pore plate. By means of the method, not only can effusion backflow be effectively overcome, but also the dosage of chemical agents can be reduced, the cost is saved, effective time of a measure is increased, and the method can be widely applied to the exploitation process of natural gas and coal bed gas.

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 ...
