Method, device and storage medium for determining fracturing plan for shale gas wells

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, abandoned formation pressure and cumulative gas production of each gas well, as well as the Lan type volume and Lan type pressure of the shale reservoir corresponding to each gas well , porosity, water saturation, density and adsorbed methane density; determine the initial gas content, residual gas content and waste gas content of each gas well; determine the ultimate recoverable reserves of each gas well; select the ultimate recoverable reserves from multiple gas wells For the gas well with the largest reserves, the fracturing stimulation plan of the selected gas well is determined as the shale gas well fracturing stimulation plan. The ultimate recoverable reserves of each gas well determined by the application through actual production data are relatively accurate and objective data, and then 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. Shale gas well fracturing schemes play a decisive role in the development of shale gas, and there are many fracturing schemes that can realize the exploitation of shale gas in shale reservoirs. In the process of shale gas exploitation, the final recoverable reserves of shale gas corresponding to different fracturing schemes will not be the same. Usually, in the process of shale gas exploitation, it is hoped that the ultimate recoverable reserves of shale gas should be as large as possible. An effective fracturing plan for shale gas wells. [0003] In related technologies, during the exploitation of sha...
