塔河9区三叠系下油组油藏精细地质建模
|
摘要
塔河9区三叠系下油组油藏属大底水、薄油层、受构造控制的砂岩孔隙型块状底水未饱和油藏。该区块的地质建模过程,采用目前较为先进的Petrel软件,充分利用钻井、地震、测井、地层对比信息,结合夹层解释结果,在孔渗曲线的基础上,选用不同的建模方法,通过对各种随机模型的评价,最终建立了接近油藏实际地质特征的三维精细地质模型。
The 9th Block of the Tahe Oilfield reservoir is a block with complicated fault system and edge-bottom water in the lower section of the lower oil formation.Petrel software is used for the 3D geological modeling of this block,which makes full use of drilling,seismic,well log and stratigraphic correlation data.This paper presents a practical 3D geological 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.
