undersaturation salt water drilling fluid

On the basis of the feature of salt beds,the undersaturation salt water drilling fluid is determined.

分析巴楚地区盐膏层矿物理化性能 ,针对塔里木巴楚地区盐膏层含膏量大等特点 ,通过确定巴楚地区欠饱和盐水钻井液 [Cl-],优选有机处理剂单剂 ,高温高压流变性实验优选出一套耐温高密度欠饱和盐水硅酸盐钻井液体系 ,该体系具有良好的耐温、抗盐膏和抑制能力。

Lately, Jiangsu oil field drills lots of salt wells locating in Hongze and Huaiyin, saturated saltwater drilling fluids is used, the concentration of Cl- is very high; various additives are added into the drilling fluids; the conductance of drilling flu.

近年来，江苏油田承钻了位于洪泽、淮阴一带的盐井，使用饱和盐水钻井液。
