摘要
王家岗油田王43断块区是典型的复杂断块油藏,目前含水高、开发矛盾突出、地质基础薄弱,下一步开发调整、提高采收率工作迫切需要可靠的精细地质模型。针对其断裂系统复杂的油藏地质特点,综合应用多项关键技术,开展精细地质研究,建立了复杂断块油藏三维精细地质模型,主要包括:缺乏对比标志的地层对比技术、复杂断块油藏低序级断层识别技术、精细油藏类型划分以及精细三维地质建模技术。该研究结果为王43断块后续开发调整提供了可靠的地质依据。
Wang-43 block of Wangjiagang oilfield is a typical complex fault block oil reservoir.At present it is of high water cut,prominent development contradiction and weak geological foundation.The development adjustment and EOR in the next step urgently need reliable fine geological model.Aiming at the reservoir geological characteristics of complex fracture system,with the integrated application of a number of key technologies,fine geologic research has been carried out and the fine 3D geological model of complex fault block reservoir has been established.In complex fault block oil reservoir,affected by the contemporaneous faults,the stratigraphic loss is serious and lack of correlation marker stratigraphic correlation technology,low-grade fault identification technology,fine reservoir classification and fine 3D geological modeling technology.The research results can not only provide reliable geological guidance for subsequent development adjustment of Wang-43 block but also provide reference for similar reservoir development study.
