【摘要】 吐哈盆地连木沁油田白垩系油藏断裂系统复杂,属于块状边底水油藏。在该区块的地质模型建立过程中,采用了目前较为先进的Petrel软件,充分利用钻井、地震、测井、地层对比等信息,结合夹层反演结果,在岩相描述曲线、孔渗曲线的基础上,选用不同的建模方法,通过对各个随机模型进行对比评价分析,最终建立了接近油藏实际地质特征的全三维精细地质模型。更多还原

【Abstract】 The precision of a geologic model is the most critical step for fine reservoir description, not only relating directly to the accuracy of numerical reservoir simulation, but also affecting the validity of a prediction scheme. The Cretaceous reservoir in Lianmuqin oil field is one with complicated fault system and edge-bottom water. Petrel software is used for the 3D geologic modeling in this block, which features a full use of drilling, seismic, well log and stratigraphic correlation data. This paper presents a practical 3D geologic model through seismic inversion, integrated with lithofacies curves and porosity and permeability curves as well as evaluations of various stochastic models and modeling methods available更多还原
