Abstract

The invention discloses a determination method and device for the shale gas well fracturing reformation scheme and a storage medium, and belongs to the technical field of oil and gas exploitation. Themethod comprises the steps that the formation temperature, the gas deviation factor, the initial formation pressure, the production formation pressure and the cumulative gas production of each gas well in multiple gas wells are acquired, and the Langmuir volume, the Langmuir pressure, the porosity, the water saturation, the density and the adsorbed-state methane density of the shale reservoir corresponding to each gas well are acquired; the initial gas content and the residual gas content of each gas well are determined; the fracturing reformation volume of each gas well is determined; and the gas well with the maximum fracturing reformation volume is selected from the multiple gas wells, and the fracturing reformation scheme of the selected gas well is determined as the shale gas well fracturing reformation scheme. By means of the method, the fracturing reformation volume, determined by actual production data, of each gas well is quite accurate and objective data, and therefore the more optimized shale gas well fracturing reformation scheme 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...
