ZJD构造E₁f₁段含气砂岩储层非均质性强, 且受到围岩及泥浆侵入影响, 利用常规测井资料对储层流体性质的评价十分困难。通过对“精测”反演方法基本原理的介绍及E₁f₁段含气砂岩储层特征的分析, 将“精测”反演方法应用于E₁f₁段含气砂岩储层的处理, 确定了储层流体性质的“精测”判别标准, 取得了一些新的研究成果。

The heterogeneity of gas-bearing sandstone reservoir of E₁f₁ member in ZJD structure is high. The effects of wall rock and mud invasion on the reservoir impede the evaluation of flow properties in the reservoir from logging data. Based on an analysis of the principles of "ACCUTLOG" inversion method and the properties of gas-bearing sandstone reservoir of E₁f₁ member, we performed "ACCUTLOG" inversion on the data from the reservoir. Desired results have been achieved.
