通过对孤岛油田南区Ng3-6单元二元复合驱精细地层研究,对单元剩余油分布规律进行再认识的基础上,探索出新井、完善井网、细分层系注聚、优化二元注入配方等的一套能够很好的适用于二元复合驱开发单元的剩余油挖潜措施,取得了较好的效果。 Based on the study of the subtle formation of binary composite flooding of Ng3-6 unit in the southern part of Gudao Oilfield and the re-recognition of the distribution of remaining oil in the unit, new wells were explored to improve the well patterning and fine-grading system. The binary injection A set of formulas and so on can be well applied to the residual oil tapping potential measures of the binary compound drive unit, and achieved good results.
