摘要
某油田西区油藏作为主力开发地区,到了开发中后期主要产油区含水率增加,剩余油分布不能明确刻画。采用深化沉积相研究,明确沉积河道走向,找寻剩余油富集区,进而提出改进措施,实现精细开采,提高本区块的开采率,提高石油产量。
In the west area of an oil field in the middle and late stage of development,the water cut of the main production area increased,and the distribution of remaining oil could not be clearly described.The study of sedimentary facies was adopted to clarify the trend of sedimentary channel and find the remaining oil accumulation area,and then improvement measures were put forward to realize fine development,improve the recovery rate of this block and increase the oil production.
