摘　　要：为了深化认识页岩气井增压开采储量预测,基于焦页A平台三口增压气井的生产动态资料,利用7种不稳定产量分析法对平台气井增压开采前后可采储量进行预测研究,并通过方差分析法和邓肯氏新复极差法比较,对预测结果进行差异性分析与评价。结果显示,RTA、Agarwal-gardner、Transient、NPI四种方法的预测结果较为可靠,能有效评价焦石坝区块气井增压开采效果,为气田下步开发提供理论依据。In order to deepen the understanding of the prediction of the pressurized production reserves of shale gas wells,based on the production dynamic data of three pressurized gas wells in Jiaoye A Platform,seven unstable production analysis methods are used to predict the recoverable reserves before and after the pressurized production of shale gas wells in Jiaoye A Platform.The variance analysis and Duncan's new complex range method are compared to evaluate the difference of the predicted results,showing that the prediction results by the four methods including RTA,Agarwal-gardner,Transient and NPI are relatively reliable,which can effectively evaluate the pressurized production effect of gas wells in Jiaoshiba Block and provide a theoretical basis for the next development of Fuling Shale Gasfield.
