【摘要】 针对G393区块储层存在非均质性强、低孔低渗等特征,综合地震、测井、地质、油藏等学科对该地区储层进行了精细地质建模。在构造模型的基础之上,结合沉积微相研究成果,建立了各小层的沉积微相模型;并利用相控建模技术,采用序贯高斯模拟方法建立了各小层的储层物性模型,描绘出储层内部各种非均质隔档,确定了影响开发效果的各种地质因素,指出了有效的调整挖潜位置,为井位优化部署提供了参考依据。更多还原

【Abstract】 Firstly the paper points out that Gang 393 block reservoir is characterized by stronger heterogeneity and dominated by low porosity and low permeability. Then it discusses the refined geological modeling according to comprehensive seismic,logging,geology,reservoir and other disciplines. On the basis of the Structural model,sedimentary microfacies model is established for every layers,which combines with research achievements of sedimentary microfacies. The reservoir physical model controlled by microfacies model is built up by using sequential Gauss simulation method,which describes the internal reservoir heterogeneous barrier,and determines various geological factors affecting development result. Finally it points out the effective adjustment position,and provides the reference basis for deployment optimization of well location.更多还原
