摘要
针对中高孔渗条件下,低阻储层识别难度较大的问题,利用工区气测资料、三维定量荧光和地化热解轻烃等数据,开展低阻成因录井含油气综合评价工作.研究表明:(1)目的层低阻成因主要高含量束缚水、黏土矿物附加导电性、骨架矿物导电和钻井液浸入地层等方面造成;(2)录井气测和荧光数据组合,地化热解轻烃和荧光数据,录井气测和地化热解轻烃组合等三类较好的构成了低阻储层含油气综合评价,其中气测与地化组合相对较好的代表了含油气性的特征.
Abstract
In view of the difficulty of identifying the low resistance reservoir under the condition of medium and high pore permeability,the cause of low resistance,mud logging and production application of the comprehensive evaluation of oil and gas were carried out by recording FLAIR and gas measurement,3-D quantitative fluorescence and geochemical pyrolysis light hydrocarbon.The study shows that:(1)the causes of high content bound water,additional conductivity of clay minerals,skeleton mineral conductivity and immersion of drilling fluid into formation;(2)the combination of gas measurement and fluorescence data,hydrocarbon and fluorescence data,and gas combination constitute the comprehensive evaluation of low resistance reservoir,including gas measurement and gas combination.
