摘要： 双河油田ⅧⅨ油组经历了3 0多年的开发, 目前已进入特高含水阶段。针对该区块地层特点, 利用人 造非均质岩心研究注水倍数、 注入速度与非均质性的关系。结果表明, 高注入水倍数下, 虽然含水率很高, 但累计产 油量仍然比较有经济价值; 渗透率级差对低渗透层的采收率影响比较大; 提高注入水倍数与注入速度, 室内实验极 限采收率增加; 现场注入速度在0. 8~1. 2mL /m i n。

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 injection,injection rate and heterogeneity. The results show that under high multiples injecting 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 injection and the injection rate,the ultimate recovery of laboratory experiments can be increased;they suggest that the injection rate should between 0.8~1.2 mL/min.

Key words: Artificial heterogeneous cores,    ,  Multiple injection,    ,  Injection rate,    ,  Recovery ratio
