Problems solved by technology
At the present stage, simple devices are mostly used in bioincrease experiments from small-scale small particle size sample experiments to gradually enlarged experimental scales. The experimental steps are basically completed manually, and various experimental links are prone to experimental failures due to unknown reasons.

Description
technical field [0001] The invention relates to the technical field of biological stimulation of coalbed methane, in particular to an experimental system of biological stimulation of coalbed methane. Background technique [0002] Under the background of "dual carbon", coalbed methane, as a high-quality energy with high calorific value, high cleanliness, low pollution and wide range of uses, can provide a great guarantee for my country's energy supply. However, low single well production and low oil recovery caused by permeability have seriously affected the stable production of CBM wells. Studies have found that conventional hydraulic fracturing and other methods have extremely limited stimulation effects on coalbed methane wells, and other effective stimulation methods are also being actively studied. Bio-stimulation (microorganisms accelerate the degradation of coal to produce methane) has great market prospects due to its small reaction pollution, wide application range,...
