摘　　要：借鉴常规油气田研究方法和天然气物性参数计算式,推导了页岩气水平井物质平衡方程,将油藏工程方法和数值计算方法相结合,利用计算机编程计算页岩气水平井在不同生产制度下的产量、地层压力、孔隙度等相关参数的变化。同时讨论了在不同生产制度下的物质平衡方程的使用方法。结果表明基于物质平衡原理的生产动态分析方法,计算参数少,计算量小,具有一定的现场应用价值。By using conventional methods for oil and gas field research and correlations of natural gas physical parameter calculation,a material balance equation for horizontal wells of shale gas reservoirs was deduced in combination of reservoir engineering and numerical simulation,by which the variation of gas production,formation pressure and porosity under different production modes were obtained,the application of material balance equation under different production modes was discussed.The simulation results demonstrate that the dynamic production analytical method based on material balance equation is valuable for field application,and requires less parameters and smaller computation.
