摘要
以大港港东油田二区复杂断块油藏为例,综合地震、钻井、地质等认识,采取重点单砂层控制、层次模拟断层的分步模拟方法建立了研究区的构造模型,解决了不同断块间构造成果数据的矛盾和井点分层数据合理性等问题,克服了单砂层多而薄、断层发育且产状变化大等技术难题,为下一步的沉积微相模拟、物性参数模拟以及利用油藏数值模拟进行剩余油的挖潜等工作提供地质依据。
This paper took complex fault- block reservoir in AreaⅡ of Gangdong oilfield of Dagang as an example,established the structural model of the research area by applying the method of key single sand layers controlling and fault classification time step simulation based on the knowledge of seism,drilling and geology.The contradiction of structural product data among different fault- blocks has been solved and the hierarchical data of sand members in well points has been made reasonable.Finally,the reliable analysis for the structural model has been conducted,many technical problems such as thin single sand layers,well- developed faults,and variable stratigraphic production have been solved.A reliable guideline for sedimentary microfacies simulation,physical parameters simulation and the potential tapping of residual oil with reservoir numerical simulation is available.
