渭北油田延长组储层四性关系的研究

Study on the Relationship between Four Properties in Extension Reservoir Group in WEIBEI Oilfield

储层"四性"关系是指储层的岩性、物性、电性和含油气性之间的关系。本文通过结合测井、录井、岩心、分析化验和岩电资料对渭北油田延长组储层四性关系进行了综合分析研究,明确了其储层四性之间的关系,进而为油层解释和储层评价奠定了基础。

＂ Four properties＂ relationship of reservoirs refers to the relationship among reservoir lithology,physical property,electric property and oil-gas bearing possibility.In this paper,well logging,mud logging,core analysis of laboratory test and rock electricity data have been combined to comprehensively analyze and research the ＂four properties＂ relationship of Yanchang formation in WeiBei oilfield in order to confirm ＂ Four properties＂ relationship of reservoirs and then lay foundations to reservoir interpretation and reservoir evaluation.
