Abstract

The application discloses a method, device and storage medium for determining a shale gas well fracturing reconstruction scheme, belonging to the technical field of oil and gas exploitation. The method includes: obtaining the formation temperature, gas deviation coefficient, initial formation pressure, production formation pressure and cumulative gas production of each gas well in the plurality of gas wells, and the Lane volume, Lane pressure, and Porosity, water saturation, density, and density of adsorbed methane; determine the initial gas content and remaining gas content of each gas well; determine the volume of fracturing stimulation for each gas well; select a gas well with the largest volume of fracturing stimulation from multiple gas wells , and determine the fracturing stimulation plan of a selected gas well as the shale gas well fracturing stimulation plan. The fracturing volume of each gas well determined by the application through actual production data is relatively accurate and objective data, so that a more optimized fracturing plan for shale gas wells can be determined.

Description

technical field [0001] The present application relates to the technical field of oil and gas exploitation, in particular to a method, device and storage medium for determining a shale gas well fracturing reconstruction plan. Background technique [0002] Shale gas is a kind of unconventional natural gas resource, and the related development technology has gradually matured. Since the shale gas well fracturing stimulation plan plays a decisive role in the development of shale gas, in order to realize the full development of shale gas, the most effective fracturing stimulation plan can be determined. Usually, the fracturing volume of a shale gas well can be the main means to evaluate the quality of a fracturing program. Therefore, the optimal fracturing program can be selected by calculating the fracturing volume of a shale gas well. [0003] In related technologies, the microseismic monitoring method is mainly used to calculate the fracturing volume of shale gas wells. Amon...
