摘　　要：整装油藏进入特高含水开发后期,开展精细油藏描述和剩余油描述提高采收率是实现整装油藏稳产增产的关键。针对仅依靠井点插值井间不确定性强的问题,本文研究了基于井震联合的储层精细描述技术,以地震资料优化处理为基础,以地震约束地质、动态约束静态的双约束模式建立三维精细地质模型,通过建模数模一体化技术精细落实剩余油。应用该技术建立的三维地质模型储量吻合率达98%以上,历史拟合率为92%,根据油田精细描述成果,共实施扶长停、改层工作量15井次,措施后增油54 t/d,为区块精细开发奠定了基础,对于同类型油藏具有重要借鉴意义。In the later stage of ultra-high water cut development,the key to achieve stable production and increase production is to carry out fine reservoir description and residual oil description to enhance oil recovery.In order to solve the problem of strong uncertainty between wells only relying on well point interpolation,this paper studies the reservoir fine description technology based on the combination of well and seismic data.The double-layer structure of seismic constraint geology and dynamic constraint static is used The constraint model is used to establish 3 D fine geological model,and the remaining oil is further refined through the integration of modeling,numerical simulation and other technologies.By using this technology,the reserves coincidence rate of the established 3 D geological model is more than 98%,and the historical fitting rate is 92%.According to the results of fine description of the oilfield,15 well times of supporting Chang ting and changing layers are implemented,and the oil production is increased by 54 t/d after the measures,which lays the foundation for fine development of the block and has important reference significance for similar reservoirs.
