【摘要】 本文综合地震、测井和地质的研究成果建立地层格架,通过对气藏顶底层面断层线的精确编辑,弄清气藏内部断层之间复杂的切割关系,从而较准确地反映地下地质体三维空间分布特征;结合相控建模,利用序贯指示随机模拟建模方法进行气藏的属性建模,表征了储层的三维空间非均质性以及含油气性质。本次建模为油藏数值模拟打下了良好的基础,为拓展SJF组勘探开发和挖掘潜力、寻找有利储层发育带和天然气分布规律提供了有力依据。更多还原

【Abstract】 Combined the seismic data and well logs with the geological results, the stratigraphic framework were set up. The fault lines of both top and bottom surfaces can be determined accurately in order to clarify the complicate cutting relationship among the faults. Based on the facies-controlled modeling, sequential indicator random simulation modeling was used to model the gas reservoir’s attributes and to characterize the reservoirs’ 3D space heterogeneity and oil-bearing condition. The model sets a good foundation for numerical reservoir simulation, and provides the basis for seeking the regularity for advantageous reservoir and gas distribution in SJF formation.更多还原
