| 摘 要： | 针对低渗砂岩气藏开展了储层压力条件下的气体渗流特征理论和实验研究,包括研究滑脱效应的定压差高压渗流实验和研究高速非达西流现象的定回压高压渗流实验.研究结果表明:低渗砂岩气藏储层中气体渗流的滑脱效应可以忽略不计;实验气测岩样绝对渗透率时,应用加回压提高平均压力的实验方法测得的绝对渗透率更为准确;压力梯度达到一定的临界值后...

| Abstract: | Theory analysis and experiments have been done to study on percolation characteristics of gas in sandstone gas reservoir with low-permeability under reservoir pressure,including gas slippage effect and the phenomenon of high-speed non-Darcy flow.The experimental results show that the gas slippage effect of low-permeable reservoirs can be neglected;when absolute permeability of rock samples were measured by gas,the data,which were measured under the increased average pressure by adding back pressure,is more ... |
