定位组合调驱技术提高采收率实验研究
摘要
Abstract
The EOR mechanism by positioning profile control - chemical displacement combination technology was studied by means of microscopic simulation model and resin cementing cores. In order to research the EOR result of the technology, the profile control experiment and chemical oil displacement experiment are carried out separately. The results show that the oil displacement result of positioning profile control-chemical oil displacement combination technology is not the simple addition of the profile control and chemical oil displacement,and there is synergistic effect between them,or they strengthen EOR result each other. The profile control experiments of cores show that,for the serious heterogeneous reservoirs with channeling paths,there is the best profile control result when the rheology of replacement slug is the same as that of main slug,the profile control depth is one third of reservoir,and the profile control opportunity is selected at the water cut of 90%. Comparative analysis shows that the positioning profile control-chemical oil displacement combination technology has very good EOR effect.关键词
