This paper introduces the research on the geological parameters and process parameters of CO2 foam fracturing in low pressure and low production gas wells, expounds the advantages of CO2 foam fracturing and the geologic adaptation conditions of CO2 foam fracturing in low pressure and low production gas wells. The results show that: According to the principle of well selection and selection determined by the study, the geology scheme design of fracturing and reformation is implemented, and the CO2 foam fracturing reformation is carried out on the low-pressure and low-production gas wells to obtain obvious transformation effects and economic benefits.
