摘要
本文以H区Y10 油藏为例,通过地层能量、水驱状况和油藏采收率三个方面评价开发效果,利用数值模拟预测方法研究剩余油分布规律、精准部署加密调整井位并预测调整效果,开展矿场试验,分析加密调整潜力.研究表明:研究区受高采液强度开发及井筒套破影响,水驱效果变差,采出程度低,局部剩余油富集,数值模拟预测加密调整可有效提高油藏最终采收率,矿场试验证明加密调整效果良好、具有可实施性,建议进一步扩大加密调整范围,提高油田采收率.
Abstract
Taking Y10 reservoir in area H as an example,this paper evaluates the develop-ment effect from three aspects,formation energy,water drive status and oil recovery factor.The distribution of remaining oil is studied by numerical simulation,the infill adjustment well location is precisely deployed and the adjustment effect is predicted,field test is carried out and the infill adjustment potential is analyzed.The results show that the study area is af-fected by the development of high production fluid strength and wellbore casing breakage,the effect of water flooding is worse,recovery degree is lower,and the remaining oil is en-riched locally in the study area.Numerical simulation predicts that the adjustment of reser-voir infill can effectively improve the ultimate oil recovery.The field test shows that the infill adjustment has good effect and practicability,which can further expand the infill adjustment range and enhance oilfield recovery efficiency.
