摘　　要：以雷观1井区为研究对象,首先,综合利用钻井、测井、地震和地层对比信息,并建立构造及骨架模型。以沉积微相平面图作为沉积相模拟的趋势约束条件,建立沉积微相三维模型。其次,依据相控建模思路及各微相物性参数的分布特征,采用相控方法建立三维孔隙度模型和渗透率模型。最后,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,为目标选择、井位部署、现场跟踪和开发方案的优化提供了依据。Firstly, based on the comprehensive research of drilling, logging, seism and stratigraphic correlation information, the structure model are reasonably established for the Leiguangl block. With the plane graph of sedi-mentary microfacies as the trend of sedimentary facies simulation constraints, sedimentary microfacies 3 D model is established . Secondly, on the basis of the facies - constrained stochastic simulation and the distribution feature of macrofacies property parameters, 3D porosity model and permeability model is established by facies - constrained method. Finally, the 3 D geological model is used to extract the electric log of planed wells for the selection of tar-get, deployment of well location, field trace and optimization of development plan.
