Shale gas well fracturing transformation scheme determination method and device and storage medium

Abstract

The invention discloses a shale gas well fracturing transformation scheme determination method and device and a storage medium, and belongs to the technical field of oil and gas exploitation. The method comprises the steps that the stratum temperature, the gas deviation coefficient, the initial stratum pressure, the production stratum pressure, the wasteland stratum pressure and the cumulative gasproduction rate of each gas well are obtained, and the Langmuir volume, the Langmuir pressure, the porosity, the water saturation, the density and the adsorbed state methane density of a shale reservoir corresponding to each gas well are obtained; the initial gas content, the remaining gas content and the abandoned gas content of each gas well are determined; the final recoverable reserves of each gas well is determined; and the gas well with the maximum final recoverable reserve is selected from the multiple gas wells, and a fracturing transformation scheme of the selected gas well is determined as a shale gas well fracturing transformation scheme. The final recoverable reserve of each gas well determined through the actual production data is accurate and objective data, and then the more optimized shale gas well fracturing transformation 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. 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...
