摘　　要：本文针对低渗透砂岩储层,确定了地下空气渗透率的影响因素为弹性压缩及气体滑脱效应,制定了相关关系和校正图版,给出了校正经验公式,以便预测不同埋深、不同渗透率级别的地下空气渗透率,并给出一套地下空气渗透率校正方法。为研究低渗透油层产能状况,评价油层以及预测控制储量和远景储量,提供必要的研究手段和方法。The factors affecting the value of in situ air permeability of a low permea- bility sandstone reservoir rock are recognized to be the effect of rock compressi- bility and gas slippage.Correlations between various parameters and emprical equ- ations as wall as calibration curves are construction for correction so as to predi- ct the in situ permeabilities of rocks with various laboratory determined perme- abilities to various depth of burial.This technique provides necessary means in the studies of the productivity of such low permeability rock formations,reser- voir evaluation,active reserve estimation and resource estimation.
