| 摘 要： | 压汞法测定储层岩石毛管压力曲线存在麻皮效应。岩样粗糙外表面与水银接触面之间的空腔体积是产生麻皮效应的根源。在大量实验基础上,取得河南油田储层各类岩性砂岩的麻皮效应数值范围,分析了其对毛管压力资料的影响,并依此对毛管压力曲线进行修正,以提高毛管压力资料质量,方便使用。

| Abstract: | There exists pockmarks - effect during the PC - Curve determination by mercury injection method. It is found that the pore volume between the surfaces of coarse sample and the mercury is the origin of pockmarks -effect. Based on a lot of experiments, we have obtained the range of pockmark - effect values of various reservior sandstones in Henan Oil Field. The action of pockmark -effect on capillary pressure is analyzed and found use in capillary pressur curves. |
