摘　　要：针对大庆葡萄花油田南部黑帝庙油层油气水分布规律复杂、缺乏油气水层测井解释标准的情况,充分利用已有的研究成果,在现有的岩心、试油和测井资料的基础上,开展储层"四性"关系研究,建立适应标准电测图和横向测井图的油气水识别图版,从而对研究区的标准曲线进行油层与水层识别,确定黑帝庙油层油水分布的范围和特点;综合天然气模糊识别及AVO烃类检测方法,确定葡南油田黑帝庙油层油气分布区域;在综合分析黑帝庙油层油气水宏观分布规律的基础上,优选有利布井区,部署评价井。在黑帝庙油层油气水分布规律的基础上,优选出油气有利区15.22km2,部署评价井18口,已实施钻井13口,预测结果与实钻井的符合率达到92.3%。研究表明,葡南油田黑帝庙油层构造高部位、深大断裂附近或断裂密集带、储层较发育的地区是油气富集的有利区。油层主要发育在黑帝庙一组下部的4、5和6号层,气层主要发育在黑帝庙二组顶部的1号层。The gas and water distribution is complex and lack of standard interpretation of oil-gaswater logging in Heidimiao oil layer of Putaohua oilfield.Study of the relationship of different reservoir physical properties is carried out and standard electrical mapping and lateral logging of oil gas water identification plate are established to determine the oil and water layers through standard curves,and to determine the distribution scope and characters.Comprehensive fuzzy recognition and AVO hydrocarbon detection method are used to complete the distribution area of Heidimiao reservoir in Putaohua oilfield.On the basis of comprehensive analysis of oil-gas-water layer distribution,favorable drilling wells are selected for evaluation.Accordingly,a favorable area of 15.22km2 isselected and then 18 evaluation wells are arranged in which 13 wells are put into effect.The coincidence rate for prediction result and practical drilling reaches 92.3%.It is considered that the positions of structural high,large scale faults and densely populated faults are favorable places for the accumulation of oil and gas.Oil layers mainly occur in the 4,5and 6layers on the bottom of MemberⅠ of Heidimiao and gas occurs at the top of MemberⅡ of Heidimiao.
