摘　　要：位于松辽盆地中央坳陷区龙虎泡-大安阶地的龙虎泡油田受储层纵向及平面非均质性影响,开发效果逐年变差,表现出油田含水上升速度加快,自然递减率上升的问题。为改善油田开发效果,应用数值模拟方法优化了不同剩余油类型的油水井对应调整方式,通过室内岩心驱替试验得到不同渗透率储层的合理注采调控参数。现场应用结果表明,采用水驱综合挖潜技术后,含水上升速度和自然递减率下降,注采剖面得到调整,提高了储层动用程度,取得了较好的施工效果。Longhupao Oilfield,which is located in the central depression area(Longuupao—Da'an terrace)of the Songliao Basin,is affected by vertical and areal heterogeneity that lead to rapid water-cut increasing rate and natural decline rate,these suggest that its development effect has become worse year by year.In order to improve the development effect,numerical simulation is adopted to optimize the ways of corresponding adjustment in oil and water wells for various types of remaining oils,and the rational injection-production regulation parameters for reservoirs with different permeability are attained by means of laboratory core flooding.The field application shows that the corresponding adjustment and regulation parameter optimization of injection and production wells can effectively reduce the water-cut increasing and natural decline rates,improve the injection-production profile,and ultimately enhance the reservoir producing degree.
