The invention discloses an infilled well fracturing design method,
system and equipment based on a movable area and a medium, and belongs to the technical field of unconventional
natural gas exploration and development. The method comprises the following steps: S1, establishing an infilled well fracturing
parameter design model of a target block; s2, the production process of an implemented well pattern is simulated, and a pressure field before fracturing of the infilled well is obtained; s3, carrying out four-dimensional stress dynamic calculation in an oil and gas reservoir exploitation process to obtain a stress evolution result, and updating related geological parameters in the model according to the stress evolution result; s4, identifying the area of a movable region of the infilled well in the updated fracturing
parameter design model of the infilled well; and S5, according to the area of the movable area of the infilled well, fracturing section grading is conducted on the infilled well, and differentiated fracturing construction
parameter design is conducted on all stages of graded fracturing sections. According to the method, finer differential fracturing design of the infilled well can be carried out, the fracturing effect of the infilled well is improved, meanwhile, pressure channeling is avoided, and the overall productivity of an infilled well group is increased.
