砂岩-非离子表面活性剂的润湿性及酸液助排性能

Wettability and Cleanup Efficiency Between Sandstone-Non-ionic Surfactant

利用Washburn方程测量固体粉末的润湿性,研究了20%的HC l中OP-4、OP-8、OP-10溶液与石英砂固体粉末的接触角,用JZHY-180型界面张力仪测定了表面张力的大小,并由此讨论了20%的HCl中OP系列非离子表面活性剂在固体粉末的润湿性,表面张力与助排率的关系。

By using washburn method to measure the wettability of the solid powder, the research of the wettability of OP - 4, OP - 8, and OP - 10 solution with the sandstone powder in 20% HC1 is conducted in this paper. With the help of JZHY - 180 interracial tensiometer, the surface tension is measured. Finally the relationship between the wettability, the surface tension and the cleanup efficiency of OP non-ionic surfactant in 20% HCt is discussed.
