摘要
通过浊点和岩屑回收率测定，研究了聚乙二醇在几种无机盐水溶液中对岩屑的抑制作用。在ＮａＣｌ、ＣａＣｌ２水溶液中，只有在浊点以上聚乙二醇才具有良好的抑制作用；而在ＫＣｌ水溶液中，聚乙二醇在任何情况下都具有良好的抑制作用。这说明聚乙二醇和氯化钾有协同作用。
The shale inhibition by polyethyleneglycol in aqueous incrganic salt solution is studied through measuring the cloud point of the solutions and the recovery of the drilling cuttings rolled in the solutions. It is shown that polyethyleneglycol in NaCl and CaCl 2 solutions is inhibitory only at temperatures above the cloud point of the solution while in KCl solutions - in all the cases studied. The experimental results are reasoned.
