摘要
本文介绍了我国首例碱－复合表面活性剂－聚合物三元复合驱油提高采收率矿场试验的全过程。试验结果表明，三元复合驱油剂具有良好的注入性能和很强的驱油能力，在水驱开采末期能大幅度降低油井含水，提高原油采收率达１１．６％，采出水驱残余油的２６．０％。
This paper pressents the results of the first case of A/S/P flooding in China performed in Guantao formation in Gudong Oil Field,Shengli. Four chemical solutions: ①0.1% P (3530S) in 0. 051PV;②(1. 34 %NaCO3+0. 224% OP-10+0. 202% CY-1) in 0. 05PV;③(1. 0984% Na2CO3+0. 302%OP-10+0. 062 % CY-1+0. 364%0 3530S) in 0. 395PV;④0. 0536% 3530S in 0. 096PV,were injected into 5 wells successively from Aug 1, 1992 to June 24 , 1993 and are followed by water flood until the water cut in 9 producing wells will reach its previous value. These flooding solution possess good injectivity and oil displacement efficiency. During the pilot test up-to-date water cut decrease and additional oil recovery are observed in all but one producing wells. The ultimate oil recovery enhancement will 11.6% of OOIP.or 26. 0% of ROIP.
