在综合分析X油田地质特征(特别是储层沉积相特征)和岩心资料的基础上,分析了黄铁矿、粘土附加导电性、泥浆侵入、孔隙中束缚水对X油田电性测井响应的影响,找出了X低阻油层成因:高毛细管束缚水形成的导电网络,降低了油层电阻率,为X油田低阻油层的测井评价研究提供了依据和基础。 Based on the comprehensive analysis of the geological characteristics of X oil field (especially the characteristics of reservoir sedimentary facies) and core data, the effects of pyrite, additional conductivity of clay, invasion of mud and irreducible water in pore on the electrical logging response of X oil field are analyzed The reason is that the conductive network formed by the high capillary bound water can reduce the resistivity of the oil layer and provide the basis and basis for the well logging evaluation of the X oil field low resistivity reservoir.
