页岩气水平井生产动态模型及其应用
Dynamic Production Model of Horizontal Shale Gas Wells and Its Application
摘要
Abstract
In order to clarify the production decline law and formation pressure dynamics of shale gas wells in WY block,a single well production dynamic model of shale gas reservoir was established with the shale gas reservoir material balance equation as the core,con-sidering factors such as stress sensitivity,matrix shrinkage,and multi-scale pore seepage effect.By fitting the dynamic production history of 145 gas wells in the block,the geological parameters of the model applicable to the gas wells in this block were statistically calculat-ed.The application results show that the calculated results using the model are in good agreement with the actual production data,with a compliance rate of 83%,and the model can be used to study the changes in formation pressure and the production performance of gas wells.The geological parameters of the model obtained from simulation of typical wells have good applicability,improving the fitting effi-ciency and effectiveness of gas wells in this block.Comparing the calculated results using the model with actual production data can as-sist in diagnosing problems in shale gas well production and provide a reference basis for adjusting measures.关键词
