Problems solved by technology

The above prediction methods are estimated based on resistivity curves and acoustic logging curves, and the prediction accuracy of organic carbon content is not high, resulting in poor accuracy in screening shale gas wells. Therefore, a shale gas well that can improve accuracy is urgently needed screening method

Abstract

The invention discloses a shale gas well screening method and device, a terminal and a storage medium, and belongs to the technical field of oil and gas exploration and development. According to the method, the rock uranium content and the rock density of at least one shale gas well are obtained, the rock uranium content and the rock density of the at least one shale gas well are input into a target model, the rock uranium content and the rock density of the at least one shale gas well can be mapped to the organic carbon content of the at least one shale gas well through the target model, the target gas well with the highest organic carbon content is screened from the at least one shale gas well based on the organic carbon content of the at least one shale gas well, the target model can more accurately describe the organic carbon content based on the rock uranium content and the rock density, so that the organic carbon content obtained by mapping based on the target model has higher accuracy, and the target gas well obtained by screening also has higher accuracy.

Description

technical field [0001] The present application relates to the technical field of oil and gas exploration and development, in particular to a screening method, device, terminal and storage medium for shale gas wells. Background technique [0002] In recent years, with the development of oil and gas exploration and development from conventional oil and gas reservoirs to unconventional oil and gas reservoirs, shale gas has gradually become an important development field. Shale gas is mainly located in thin interbeds of dark mudstone and light gray siltstone. Natural gas mainly occurs in adsorption and free states, including marine shale, continental shale, marine-terrestrial transitional shale, etc. [0003] In the exploration and development of shale gas wells, the organic carbon content (Total Organic Carbon, TOC) of shale gas wells is an important evaluation index. By predicting the organic carbon content of shale gas wells, it can be used to evaluate the productivity of sha...
