摘　　要：致密砂岩气藏储量丰度低,地质条件复杂,提高气藏采收率难度大。以四川盆地典型层状致密砂岩气藏新场气田J_(2)s_(2)气藏为例,采用岩心实验、动态分析及数值模拟等方法,从地质方面和开发方面对影响气藏采收率的因素进行综合研究。结果表明,地层渗流能力、含气性等地质因素以及开发井网、废弃地层压力、工程工艺等开发因素对致密砂岩气藏的采收率影响较大。研究成果可为国内外致密砂岩气藏提高采收率对策的制定提供支撑。As the tight sandstone gas reservoir has low reserve abundance and complex geological conditions,it is difficult to improve gas reservoir recovery.Taking the typical layered tight sandstone gas reservoir in the Sichuan Basin-J_(2)s_(2) gas reservoir in Xinchang gas field as an example,core experiment analysis,dynamic analysis and numerical simulation are introduced to study the factors affecting the recovery rate of gas reservoirs from geology and engineering.The results show that formation seepage capacity,gas reservoir properties,development well pattern and engineering technology are the main factors affecting the recovery of tight sandstone gas reservoirs.The research results can provide a good support for the development of EOR strategies for tight sandstone gas reservoirs at home and abroad.
