由于底水正韵律油藏的特殊性,在油藏开发后期,实施提高采收率的常规方法难以达到预期效果,油藏挖潜困难。在对羊二庄油田一断块Ⅲ5油藏地质特点分析的基础上,对开发历史上采用的各种治理手段,对断块油藏开发效果进行评价。并利用油藏数值模拟、精细油藏描述等技术,通过对油藏进行油水运移规律、底水油藏数值模拟等研究,得出油藏剩余油分布结论,进一步制定了符合油藏实际情况并在目前技术条件下可以实施的治理方法,目前已实施并取得成功。
Due to the particularity of the positive rhythm reservoir of bottom water, it is hard to achieve the expected results in the conventional methods of increasing oil recovery in the late stage of reservoir development, making it difficult for the reservoir to tap the potential. Based on the analysis of geologic characteristics of a fault block Ⅲ5 in Yangzhuangzhuang Oilfield, various control measures adopted in the history of development and evaluation of the effect of fault block reservoir development are carried out. Based on the research on the law of oil and water migration and numerical simulation of bottom water reservoirs and so on, using the techniques of reservoir numerical simulation and fine reservoir description, the conclusion of the residual oil distribution in the reservoir is obtained, And the governance methods that can be implemented under the current technical conditions have been implemented and are now successful.
