高注水倍数非均质岩心驱油效果实验研究
Heterogeneous Cres of High Inj ection Multiples Flooding Effect
摘要
Abstract
Shuanghe field ⅧⅨ oil group has been developed more than 30 years,and it has entered the especially high watery stage.According to the features of formation of the blocks,with artificial heterogeneous cores,the experimental study the relationship of multiple inj ection,inj ection rate and heterogeneity.The results show that under high multiples inj ecting water, although the moisture is very high,cumulative oil production still have more economic value;permeability ratio have a great impact on low-permeability layer;improving multiple inj ection and the inj ection rate,the ultimate recovery of laboratory experiments can be increased;they suggest that the injection rate should between 0.8~1.2 mL/min.关键词
