摘　　要：根据油田开发地质研究需要完善的方法技术，以地质建模为主要研究对象，以建模方法研究为基础，进行了胡130井区沉积微相约束地质建模综合研究。在分析目前国内外研究现状的基础上，针对地质研究工作的特点，提出根据测井解释成果，应用随机模拟的方法定量地开展沉积微相研究。应用沉积微相研究成果约束测井储层参数的分布，形成油藏数值模拟研究所需要的准确的储层三维地质模型．解决了常规油田开发地质研究过程中沉积相研究成果与储层参数分布无法有效结合的缺陷。According to the methods or techniques needed to be perfected in geological researches of oilfield development, taking geological nmdeling as a main objeet of research, a comprehensive study of constrained geological model establishment for the sedimentary microfacies of the well Hu-130 area is conducted on the basis of the research of modeling methodologies. Based on the analysis of the current research situation at home and abroad, and in the light of features of geological study work, the authors propose that, according to results of logging interpretation, the sedimentary microfacies study is quantitatively conducted with a stochastic simulation methodology. We use the results of sedimentary microfacies research to constrain the distrihution of the reservoir parameters in the well logging, and form an accurate tridimensional geological model of the reservoir required for the reservoir numerical simulation. This makes up for the shortcomings or defects in conventional geological researches of oilfield development, that is, the sedimentary faeies research resuhs cannot be effectively combined with the distribution of reservoir parameters.
