摘　　要：低渗透储层中油气测井响应不明显,以致有生产能力的低孔隙度储层与无效层段之间的差异很小,测井解释的难度很大。结合白豹油田长3油层的实际情况,抓住二次测井解释的关键——测井曲线标准化处理、"四性"关系分析和解释模版确定,建立了一套特低渗储层测井二次解释的方法,并结合岩心分析资料、试油试采资料对该油田132口井进行了二次解释,经检验符合程度达到82%,验证了该方法具有较好的推广前景。In low permeability reservoirs,the logging response was not obvious.The difference between reservoir with low porosity and productivity and inefficient intervals was small and difficult for logging interpretation.In combination with practical situation of Chang 3 Reservoir in Baibao Oilfield,the key of secondary logging interpretation was determined,which included the normalized process of logging curves,analysis of 'four characters' and interpretation chartboard.A set of interpretation methods for secondary log interpretation were established and used in 132 wells of Baibao Oilfield with coincidence rate of 82%.The practical application shows the method is efficient and is worthy of oilfield application.
