摘　　要：为改善特高含水期油藏开发效果,实现区块效益开发,通过开展精细油藏描述,形成剩余油分布定量新认识,同时结合储层分类评价结果筛选调整潜力区块,形成不同类型储层差异化调整对策。在完善注采井网的基础上,针对“双高”区域开展了流场定量表征研究,为精细化注采调整提供理论基础。根据矿场实施结果,调整后各项注水指标逐年变好,自然递减率大幅下降,调整取得较好效果,具有较大的推广意义。In order to improve the development effect of a reservoir in the extra-high water cut stage and realize the areal value-added development,a new insight into the quantitative identification of remaining oil distribution is established by carrying out refined reservoir description.Meanwhile,potential areas are screened out in combination with the reservoir evaluation results to work out varying adjustment strategies for different types of reservoirs.On the basis of further improving injection-production well pattern,quantitative characterization of flow field is carried out for“double-high”areas to provide theoretical basis for refined injection-production adjustment.According to the results of field application,the adjusted water injection indicators are becoming better year by year,and the natural decline rate decreases greatly.Therefore,with the good adjustment effect,it can be applied in other oilfields.
