【摘要】：YM32油田白云岩储层结构复杂,油藏剩余油分布类型多样、高含水后难治理,给油田实现高效稳产开发提出了挑战。对此,引入地质工程一体化理念,探索了一条针对剩余油挖潜的"嵌入型"地质工程一体化的实施路线,工程人员"嵌入"地质研究团队中。针对不同剩余油分布地质模式,联合制订出周期注氮气吞吐、水平井地质导向侧钻技术等挖潜措施;并在工程实施过程中,综合油藏地质、地球物理、钻井、试采等多学科知识和工程资料,不断调整和完善工程技术方案,实现裂缝孔隙型白云岩油藏剩余油的经济开发和效益开发,已如期建成40×104t/a产能规模,目前原油产量已连续稳产4年。地质工程一体化理念在YM32油田剩余油挖潜中的实践经验,对其他同类型油藏高效开发具有较好的借鉴意义。
[Abstract]:The complex structure of dolomite reservoir in YM32 oilfield, the variety of remaining oil distribution types, and the difficulty in controlling the reservoir after high water cut pose a challenge to the development of high efficiency and stable production in YM32 oilfield. In view of this, this paper introduces the concept of geological engineering integration, and explores a "embedded" geological engineering integration implementation route aiming at the remaining oil potential, in which the engineers "embed" in the geological research team. In view of different remaining oil distribution geological models, combined development of periodic nitrogen injection huff and puff, horizontal well geological guidance sidetracking technology, and in the implementation of the project, comprehensive reservoir geology, geophysics, drilling, In order to realize the economic development and benefit development of remaining oil in fractured porous dolomite reservoir, the production capacity scale of 40 脳 104t/a has been completed on schedule. At present, crude oil production has been stable for 4 years. The practical experience of geological engineering integration in tapping the potential of remaining oil in YM32 oilfield is of great significance for the efficient development of other reservoirs of the same type.
