摘　　要：采用覆压实验模拟与地质分析相结合的方法，对苏里格地区致密砂岩覆压孔隙度、渗透率开展研究，明确了孔隙度、渗透率随净上覆岩压的变化规律。建立了苏里格地区致密砂岩地面孔隙度、地面渗透率压缩校正经验公式，对苏里格地区致密砂岩气的储量评价具有指导作用。The porosity and permeability under overburden pressure of tight sandstone in Sulige area are studied through combining the experimental simulation under overburden pressure with geological analysis method. The law of variation of porosity and perme- ability wilh the net overlying rock pressure is defined. Empirical formulas of compression correction of surace porosity and surface permeability of light sandstone in Sulige region are established. The authors hope that the study has a guiding role in reserves evalua- tion of tight sandstone gas in Sulige region.
