简要介绍了对千米桥潜山碳酸盐岩缝洞型储层进行随机建模的方法和依据。详细阐述了建模的参数与步骤。通过对模型的分析,揭示出千米桥潜山区缝洞型储层在纵向上分为3个发育带、在平面上分为5个发育区的分布特点。并通过对总孔隙度模型与裂缝孔隙度模型之间差异性的研究,认为控制该区储量丰度和产能的重要因素是孔、洞的发育程度,而裂缝的发育则主要控制储层的横向沟通与渗透性。

The paper introduced briefly the theory and method of fracture and cave carbonate reservoir stochastic modeling in Qianmiqiao buried hill, and expatiated on the parameters and processes. Based on the analysis of the model, the character of the reservoir distribution was showed up that the reservoir occurred on three zones in section and five regions in area. According to the difference of total and fracture porosity, the conclusion was put forward that the important control factor of the reserves and production were degree of the porous and cavity, the fracture controlled mainly the connection in landscape orientation and permeability of the reservoir. These conclusions were important significance for guiding the exploration.
