摘要: 储层微相研究是油田开发后期储层非均质性精细表征及剩余油分布规律研究的重要内容。笔者从岩心资料分析入手,按照成因相→成因相组合与成因分析→测井微相模式→单井测井相分析→平面微相分析的思路,对樊家川油田延9油层河流相储层进行微相细分研究,归纳出沉积微相平面展布特征,为油田开发及剩余油分布规律研究提供重要信息。Abstract: Analysis of oil reservoir microfacies is important for the study of remnant oil and the anisotropy features of oil reservoir in later period. Based on the core analysis, and the study from genesis facies to combination and genesis analysis of genesis facies, from building loggings microfacies mode to the analysis of single logging facies, and to the analysis of plane microfacies, the author studies the subdivision microfacies of Yan 9 oil reservoir in stream facies in Fanjiachuan oil field, and using the method of mode-protracting to analyze the combination of plane microfacies.The study makes a solid geological foundation for the further development of later remanent oil.
