摘　　要：通过建立M11块油藏的数值模拟地质模型,并在此基础上进行精细油藏数值模拟,拟合程度达到86.4%。分析了该油藏平面、纵向储量动用状况和剩余油分布规律,认为剩余油分布的主要类型有5种,统计各类型剩余油潜力及其在各砂组的分布,提出了剩余油挖潜的可行措施,取得了较好的增产效果。Zhongyuan Machang Oil field M11 block is a complex depositional structure, and has entered into extra high water-cut period. Aiming at its features and difficulty, a geological model for numerical simulation was established, and on its basis the distribution of remaining oil and refined oil reservoir numerical simulation had be researched. It analyzed the producing state of the oil reserves and distribution of the remaining oil in the horizontal and vertical position, determined 5 main types of remaining oil distribution, and put forward some available adjustment measures which obtained a better yield results.
