摘要

介绍了陕甘宁盆地靖东油田长2油层的储层地质特征,评价了储层的敏感类型及程度;研究了长2油层的伤害机理,研制了强抑制正电胶低损害的钻井(完井)液体系,并进行了动态伤害评价;现场试验了6口井,取得了良好的效果。

Abstract

The geological characteristic of Chang-2 reservoir in Jingdong Oilfield of Shanganning Basin is described, and the specific type of formation sensitivity and degree of formation damage are also investigated. A highly inhibitive MMH drill-in fluid system is designed based on the study of formation damage mechanism. At the same time, dynamic formation damage evaluation is carried out. Field testing in six wells shows its effective formation protection capability.
