王庄油田膨胀性黏土特性研究
The Characteristics of Effervescing Clay Study in Wangzhuang Oilfield
-
摘要: 王庄油田属强水敏性稠油油藏。由于储层中膨胀性黏土含量很高,注水、注汽后产生水化膨胀,伤害储层,开发效果不理想。因此,对膨胀性黏土特性进行攻关研究,是开发好这类油田的技术关键。笔者应用了X衍射、红外、DTA、CEC及膨胀率测定等分析资料,重点对膨胀性黏土特性予以探讨。Abstract: The Wang zhuang oilfield belong to heavy oil reservoir of strong sensitivity.As a result of the high content of the clay in reservoir,water flooding and pour into steam produce the expansibility results that developed effect isn't ideal.Ther efore,the clay expansibility study is a key technology wich the oil field develop good result.This paper used XRD,IR,DTA.CEC and expansive rate analyses to strees on discussion of the expansibility.
