三维地质建模技术在雷观1井区的应用

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。

Application Of 3D Geological Modeling Technique In LeiGuan1 Block

Firstly,based on the comprehensive research of drilling,logging,seism and stratigraphic correlation information,the structure model are reasonably established for the Leiguang1 block.With the plane graph of sedimentary microfacies as the trend of sedimentary facies simulation constraints,sedimentary microfacies 3D 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 3D geological model is used to extract the electric log of planed wells for the selection of target,deployment of well location,field trace and optimization of development plan.
