3.
Multi-hydroxyl polymer,CXC-1,as an anti-sloughing agent for water base drilling fluids,is a yellowish liquid and is prepared by polymerization of alkylene oxides and polyhydroxylated compounds.
多羟基聚合物防塌剂CXC-1是以环氧化物及多羟基化合物共聚而成的聚合物防塌剂,为淡黄色黏稠液体。
5) inhibitor effectiveness
抑制剂效力
6) instability prevention capability
防塌能力
1.
Firstly,the velocity of the film forming by adsorption and density of the protective foil were the key factors to determine the IPC(instability prevention capability) of the drilling flui.
在试验研究的基础上对比了无机聚合物硅酸盐和有机聚合物———聚乙烯醇(PVA)、部分水解聚丙烯酰胺(PHPA)、非水解聚丙烯酰胺(PAM)和聚丙烯酸钾防塌能力的大小;由试验得出吸附成膜速度的快慢和保护膜的致密程度是决定钻井液体系防塌能力的关键因素;钻井液体系的防塌能力是无机聚合物和有机物质协同作用的结果;部分水解聚丙烯酰胺钻井液体系的防塌能力较非水解聚丙烯酰胺钻井液体系的防塌能力强;Na-CMC和PHP的加入可提高吸附膜的致密性及体系的防塌能力。
