| 摘 要： | 考察了活性剂浓度、碱浓度和聚合物种类及浓度对复合驱油体系与原油间瞬时界面张力(γt)的影响.结果表明,在一定碱和盐浓度条件下,0.3%的石油磺酸盐存在即可使γt降至超低.室内模拟驱油试验结果表明,化学驱提高采收率27.5%.本研究对于三次采油具有一定指导意义.

| Abstract: | Transient interfacial tension between mixed systems of petroleum suuonate(PS)/alka-line/polyacrylamide consisting of n-C4H9OH,NaCl and Shengli crude oil have been studied.Experimental results indicated that transient interfacial tension of mixed systems were ultra-low when the PS and Na2CO3 come up to a certain concentration,Synergistic effect betweenPS and petroleum acid soap have been observed.The oil recovery of a system with 0.3%PS,1.2%Na2CO3,0.09%polyacrylamide,1.0%n-C4H9OH and 0.6%NaCl in core is 27.5%.On the average,21. 3cm3 oil was displaced with each gram of chemical agent. |
