本文提供的HP67和TI59计算机程序可以根据电阻率—密度—声波测井系列快速分析泥质碎屑储集岩。这种分析是根据分散的粘土分布(粘土悬浮液)模型进行的。除地层水饱和度外,由密度—声波组合测井还可以求q-因数,这为确定泥质油砂岩的极限渗透率提供了依据。曾提出q值超过有效孔隙度两倍或大于0.4时的极限渗透率试验数据。但是根据现场经验,采用这种极限渗透率,特别是对于孔隙度为15~25%的砂岩,不总是令人满意的。
The HP67 and TI59 computer programs provided in this article provide rapid analysis of muddy debris reservoirs based on the resistivity-density-acoustic logging suite. This analysis is based on a model of dispersed clay distribution (clay suspension). In addition to formation water saturation, q-factors can also be calculated from density-acoustic combination logging, which provides the basis for determining the ultimate permeability of muddy oil sandstone. The limit permeability test data for which the q value exceeds twice the effective porosity or greater than 0.4 has been proposed. However, based on field experience, it is not always satisfactory to use this ultimate permeability, especially for sandstone with porosity of 15-25%.
