均衡注采提高水驱油藏采收率

Balanced Injection and Production Improve the Recovery Rate of Water-driven Oil Reservoirs

基于单元发展阶段,八区馆上现处于后续水驱阶段。对井网完善程度低,损失储量严重,高含水开发期馆陶组油藏,围绕“两率”(储量动用率、油田采收率)、“两控”(控递减、控含水),通过精细油藏分析,采取油水井综合治理措施,培养稳升井组和长寿井,改善了水驱开发效果,提高了区块采收率,对其它同类油田的水驱开发具有借鉴意义。

Based on the development stage of the unit,the upper Baqu museum are now in the follow-up water flooding stage.Due to the low degree of perfection of the well network,serious loss of reserves,and high water content during the development period of the Guantao Formation reservoir,focusing on the“two rates”(rate of reserve utilization and oilfield recovery rate)and“two controls”(control of decline and control of water content),through fine reservoir analysis,comprehensive treatment measures for oil-water wells are adopted,and stable rising well groups and long-life wells are cultivated,which improves the effect of water flooding development,increases the block recovery rate,and has reference significance for water flooding development of other similar oilfields.
