胡尖山地区长 6、长 4+5 储层有利区预测

摘要：以胡尖山油田长 6、长 4+5 油藏为例，综合应用地质资料、岩芯分析资料、测井资料以及试油资料，开展了长 6和长 4+5 油藏小层划分和对比、单井相分析，建立测井相识别模式，编制小层沉积相平面展布图，进而分析沉积相演化规律；探讨储层砂体展布以及物性分布规律，从而深入认识研究区的储层特征。在此基础上对储层进行流动单元的划分，然后结合试油资料对胡尖山油田长 6、长 4+5 油藏的储层进行有利区域的预测，为油田待开发区域的合理建产开发提供了理论指导

Prediction of Favorable Area of Chang 6 and Chang 4+5 Reservoir FromHujianshan Area

Abstract：Basedontheintegratedinformationofgeologicaldata，coreanalysisdata，loggingdataandproductiontest，thestrataclassification and contrast，and the single-well phase analysis of Chang 6 and Chang 4+5 from Hujianshan oilfield are carriedout. The recognition pattern of log facies and plane distributive maps of sedimentary facies of oil layers are also established，and then the evolution law of sedimentary facies and the exhibition of reservoir sand body and property are analyzed，which arefavorable for the recognition of the reservoir characteristics. On the basis of previous research，the flow unit of the reservoir aredivided，then combined with the test data，the favorable area of the reservoir are predicted，which can provide the theoreticaldirection for reasonable development of Chang 6 and Chang 4+5 from Hujianshan Oilfield.
