摘　　要：滩海地区地理位置特殊,钻井少,各种资料获取、采集难度大,储层横向变化大,油藏类型多样。以埕海油田为例,利用地震资料开展了大位移水平井对比,建立了地层模型和构造模型,并在地震反演数据体约束下建立了储层岩相模型,进而在岩相模型的控制下实现储层参数建模。通过三维地质模型的建立,提取了设计井的岩电测井响应特征曲线,为井位优化、现场跟踪和开发方案的优化提供了依据,最大限度地降低了产能建设过程中的风险。Reservoirs in beach area are of multiple types and vary laterally.Few drilled holes bring difficulties to acquire and collect all kinds of data.Here we use Chenghai oilfield as the example.The seismic data were used to develop the large range stratigraphic correlation of long displacement horizontal wells and setup the stratigraphic and structural model.We also set up the lithofacies model of reservoirs by means of constraint of seismic inversion data,and make the modeling of reservoir parameters based on the lithofacies model.We use the 3D geological model to extract the electric log of planed wells for the optimization of well location,field trace and optimization of development plan,therefore minimize the risk in the deliverability building.The result is positive in field operation.
