摘　　要：济阳坳陷浅层气藏丰富,含气前后储层的物性差异较大,研究合气前后岩石弹性和物性参数的变化规律,可帮助解释人员进行气藏的地震识别。本文利用三轴应力实验仪对不同岩性的岩芯进行模拟地下压力条件下的含气、水、油介质的试验,同步测量了岩芯岩石的动静态弹性参数,并分析了其变化规律。There are plenty of shallow gas reservoirs in Jiyang Depression. Whether the reservoirs contain gas or not,it makes them differ greatly in physical properties. The study of law on the elastie and physical properties of varied gas-bcaring rocks is helpful to the interpreters to seismically recognize the gas reservoirs. In this paper, three-axis stress cxperimental instrument is used in the test to simulatc different media containing gas,water,and oil in underground pressure condition for the eores with different lithologies. The dynamie and statie elastic parameters of cores are measured synehronistically,and also its variation laws are analyzed.
