摘　　要：现有开发技术条件下,不整合油藏标定采收率明显低于其他类型油藏,整体处于低采出程度开发阶段。针对不整合油藏储层发育特点及勘探开发难点,研究了不整合油藏网格系统设计方法,形成了一套精细油藏建模、数值模拟技术系列,包含多数据融合构造建模、随机模拟模型优选、动静结合物性建模、油水界面拟合技术,为不整合油藏构造落实、储层预测及剩余油精细挖潜提供技术指导。在林樊家油田L1块应用结果表明,该技术能够建立多资料统一、符合动静认识的实体油藏模型,剥蚀线位置和展布形态刻画更加精细,同时落实了储层非均质性和各小层储量。地质模型经巷道水平井验证,吻合率达100%,数模模型生产历史拟合精度达90%,可为后续井位部署和方案调整提供依据。Under the existing development technology,the calibrated recovery factor of unconformity reservoirs is obviously lower than that of other types of reservoirs,and they are in the stage of low recovery degree.Aiming at the development characteristics and exploration and development difficulties of unconformity reservoirs,a set of fine reservoir modeling and numerical simulation technologies are formed through the study on the design method of grid system,including multi data fusion structure modeling,random simulation model optimization,physical property modeling by dynamic and static combination,oil-water interface fitting technology,which can provide technical guidance for structure implementation,reservoir prediction and fine remaining oil potential tapping of unconformity reservoirs.The application of these technologies in block L1 of Linfanjia oilfield shows that to use them can establish a solid reservoir model with unified multi data and consistent with dynamic and static knowledge,describe more precisely the location and distribution pattern of denudation line,and determine the reservoir heterogeneity and the reserves of each small layer.The geological model is verified by the horizontal well in the roadway,the coincidence rate is 100%,and the production history fitting accuracy of the numerical simulation model is 90%,which provides the basis for the subsequent well location deployment and development scheme adjustment.
