Description

technical field [0001] The invention relates to the technical field of coalbed methane production stimulation experiments, in particular to a coalbed methane microbial stimulation experimental device and method based on different fracturing fluid environments. Background technique [0002] The exploitation of coalbed methane requires the use of fracturing fluids. Before exploitation, it is necessary to conduct experiments and comparisons of geology to determine the type and proportion of fracturing fluids to achieve maximum exploitation efficiency. [0003] In the experimental comparison of existing coalbed methane mining, multiple groups of fracturing devices are usually used to mine multiple extraction holes, and different fracturing fluids are used in each group of fracturing devices, resulting in inaccurate experimental data due to differences in extraction holes. , and the fracturing fluid used is put into the fracturing device after the proportion of the fracturing flu...
