摘要:

利用光学沉降扫描仪测定了常用的几种钻井液处理剂对固相粒度分布的影响，实验结果表明，处理剂８０Ａ５１，ＰＡＣ１４１，ＨＰＡＮ对Ｂａｎ土及明化镇地层土均有不同程度的絮凝作用，而Ｎａ２ＣＯ３，ＦＣＬＳ，ＮａＫ等处理剂Ｂａｎ土及明化镇地层土具有不中烈的分散作用，同时还研究了不同体系钻井液的固相粒度分布，为提高钻井速度，保护油民支提供了一些基础资料。

Abstract:

Influence of several mud treating agents in common use on the particle size distribution of solid phase indrillung fluids influence by common drillins fluids was determined with Scanning-Photo-Sedimentograph. It showed thatboth the bentonite and Minghuazh
