Abstract

The results of determining the contents of different types of bound water by the hygrometric method and the adsorption isotherm method are presented for the first time for extracted rock samples of the Bazhenov Formation. All the obtained water sorption isotherms have a well-defined S-shape, which allows calculation of the maximum possible amounts of bound water of different types (mono-, poly-, and capillary condensation) in the samples. The inflection points of the isotherms of the extracted samples fully correspond to the inflection points of the isotherms of the native samples. Based on these results, it is possible to further estimate the specific surface area of the samples and then to determine the hydrophobicity coefficient and the parameters of the associated oil saturation.

Bazhenov组岩石在烃类提取前后的结合水

摘要

首次提出了采用湿度法和吸附等温线法测定巴热诺夫组岩样不同类型结合水含量的结果。所有获得的吸水等温线都具有明确定义的 S 形，这允许计算样品中不同类型（单、多和毛细管冷凝）的最大可能结合水量。提取样品的等温线拐点与天然样品的等温线拐点完全对应。基于这些结果，可以进一步估计样品的比表面积，进而确定疏水系数和相关含油饱和度的参数。
