The evaluation of shale gas development area selection is an important part of shale gas development

and the effectiveness of evaluation methods is conducive to the efficient development of shale gas.Based on 9 candidate blocks of exploration and development mature and immature blocks in Fuling Shale Gas Field

the influence of different geological and engineering parameters on the evaluation of selected areas has been systematically analyzed

and the evaluation index of the blocks have been selected.Among these index

gas content

compressibility and economy are three important aspects of shale gas development area selection evaluation.Thereafter

the analytic hierarchy process and the mean square error method are used to determine the combined weight of the index

which improve the accuracy of the weight coefficients and establish an evaluation method for shale gas development area selection.The research result shows that in the process of selecting shale gas development areas

the main evaluation index are total hydrocarbon value measured by gas logging

fault development degree

formation pressure coefficient

topographic features

fracture development degree of target layer and porosity.According to the development practice in the Fuling Shale Gas Field

the evaluation results are in good agreement with the actual situation

indicating that the evaluation method for shale gas development area selection based on the improved analytic hierarchy process is feasible.
