Microbial preparation foam drainage gas production process

Abstract

The invention discloses a microbial preparation foam drainage gas production process which comprises the following steps: preparing diluents with different concentrations, inoculating thalli onto the diluents by using an inoculating loop, and then preserving at constant temperature to complete microbial culture operation; the cultivated microorganisms are injected into the stratum of the natural gas well, and meanwhile a foam scrubbing agent is injected into an oil pipe through foam scrubbing agent injection equipment; the method has the beneficial effects that microorganisms cultivated in different environments are injected into the stratum of the natural gas well at the same time, a certain amount of foam scrubbing agent is injected into the oil pipe to be matched with the oil pipe, the purpose of fast foam scrubbing gas production can be achieved, and the purpose of fast foam scrubbing gas production can be achieved; moreover, the microorganisms can generate a biosurfactant and various secondary metabolites in the gas well, a good cleaning effect is achieved on the near-wellbore zone of the well bottom, and the metabolites are protein, so that the environment is not polluted, and the pipeline flow is not corroded.

Description

technical field [0001] The invention relates to the technical field of foam row gas recovery, in particular to a microbial preparation foam row gas recovery process. Background technique [0002] In the process of natural gas production, the formation will produce water along with the production, and the formation water will have a great impact on the production of natural gas. Therefore, drainage and gas recovery must be done in the middle and later stages of production. Although there are many types of drainage technologies, chemical drainage Because of its high quality and low price, the advantage of simple process is that the method is actually used most in the field now, and chemicals have many side effects in production, such as the difficulty of eliminating foam after reaching the ground, and strong corrosion on production pipelines and production processes At the same time, the residues of corrosion inhibitors and the denatured substances of foaming agents form block...

[0002] In the process of natural gas production, the formation will produce water along with the production, and the formation water will have a great impact on the production of natural gas. Therefore, drainage and gas recovery must be done in the middle and later stages of production. Although there are many types of drainage technologies, chemical drainage Because of its high quality and low price, the advantage of simple process is that the method is actually used most in the field now, and chemicals have many side effects in production, such as the difficulty of eliminating foam after reaching the ground, and strong corrosion on production pipelines and production processes At the same time, the residues of corrosion inhibitors and the denatured substances of foaming agents form blockages near the bottom of the well, and the subsequent purification process of chemicals also requires a very complicated process, and a large number of other chemicals are also required, which also increases production. cost, is not conducive to practical application
