基于灰色关联法的页岩气水平井产量主控因素分析

Study on the Main Controlling Factors of Shale Gas Production Based on Grey Correlation Method

四川威远页岩气水平井单井的产量差异规律与单一地质、压裂参数的差异规律并不统一,其产量受多种因素的影响。为了提高水平井产量,运用灰色关联分析方法,研究产量与地质、工程相关的12个影响因素的关联性,确定影响页岩气水平井产量的主要地质因素。

Production difference law of single well with shale gas horizontal well is not the same as the difference law of single geological and fracturing parameters in Weiyuan,Sichuan,while its production is affected by a variety of factors.In order to improve the production of horizontal wells and realize the development of shale gas,grey relational analysis method is adopted to study the correlation between production and 12 factors related to geology and engineering.The main geological factors affecting the horizontal well production of shale gas are determined.
