摘要
文章针对大37块的剩余油分布特点,提出了堵水调剖、补孔换层和储层改造,加大分注力度,水井欠注增注,完善注采井网和确定合理井网密度,油井间开和周期注水,水气交替注入,定向压裂技术,侧钻水平井及选择合理的提液方式等开采策略,进一步提高了地下剩余油的采出率。
According to the distribution characteristics of remaining oil in Da37 area, a series of exploitation strategies are presented in this paper, including water plugging and profile control, reperforating and changing layers, reservoir reconstruction; strengthening stratified waterflooding degree, increasing water injection; improving flooding well network and confirming reasonable well spacing density; staged well opening and periodic water injection; WAG; directed vertical fracturing technique; sidetrack horizontal well; choosing reasonable extracting methods. Through the strategies mentioned above, recovery rate of remaining oil is further increased.
