摘要
我国东部油田由于受沉积环境的影响,油藏类型大部分为复杂断块油藏,物性差,非均质性强。羊三木油田三断块NgI油组是一个复杂断块稠油底水油藏,投入开发近30年,目前采出程度不足8％,开发效果一直较差。通过精细油藏描述及剩余油分布研究,搞清储层及剩余油在三维空间展布的基础上,提出三断块NgI稠油底水油藏,采取钻水平井加密与钻直井加密相结合,并配合一定的油水井措施整体挖掘油藏潜力的井网调整策略。羊H1井的钻探成功,为下一步的调整、挖潜打下了坚实基础,并对同类油藏的开发调整将具有一定的借鉴意义。
There are mainly complicated fault block oil reservoirs with bad physical property and high heterogeneity on account of the affectation of depositional environment in eastern oilfield of our country. NgI oil layer team in fault block 3 of Yang Sanmu oilfield is complicated fault block viscous and crude basal water reservoir. It has been exploited for about 30 years however the recovery ratio is at present below eight percent and the produc- tion effect is badly. The paper puts forward the adjusting strategy of drilling crowding horizontal well and crowding straight well accompanied by measures of integrally excavating producing potential for oil or water wells, through elaborate reservoir description and research on remaining oil distribution making certain oil layer and remaining oil distribution in three-dimensional space. The successful drilling and exploration of Yang H1 well makes the strong base for next adjustment and potential excavating and provides referenced signification for the producing of the same type reservoirs to some extent.
