| 摘 要： | 随着勘探技术的进步,我国发现了许多深层天然气,它的埋藏深度大于3500m。然而,气层岩石孔隙度随着埋藏深度增加而减小,结果引起核测井读数分辨率降低。采用核测井读数解释深层天然气,识别气层的分辨率极差,有时候难以发现深层天然气。本文提出的核测井孔隙度差异法,用于解释我国某气田深层天然气,获得了令人满意的效果。

| Abstract: | With the progress of petroleum exploration techniques,much deep natural-gas,with a depth of more than 3500 meters,is discovered in China.Satisfactory results have been achieved by using the Difference of Nuclear Logging Porosities Method proposed in this paper for interpreting the deep natural-gas formation in so-so gasfield of China. |
