摘　　要：LJ地区砂砾岩地层具有岩石结构复杂、储集层非均质性强、稠油和稀油并存的特点 ,利用测井资料解释含油性难度很大。以地层测试资料为依据 ,综合利用多种测井信息 ,提取反映含油性变化的测井特征参数 ;应用测井参数交会法和测井相分析法建立有效、快速识别稠油、油层和水层的标准。测井相分析法消除了用测井单参数和两参数交会解释含油性存在的多解性 ,提高子解释结果的成功率。用编制的解释软件处理了LJ地区 5 8口井的资料 ,解释结果与试油资料对比吻合程度较高。为砂砾岩储层含油性解释提供了一种有效、快速的方法 。Identifying oil bearing property of glutenite reservoir is very difficult in LJ area with complex structure, strong heterogeneity, heavy and light oil. Based on well testing data, cross plots and log facies analysis are used to establish norms and methods for effectively and visually identifying heavy oil, oil zones and water zones. Through comparison, the log facies analysis can remove the multiple results from single log data or cross plots and enhance interpretation accuracy. Data from 58 wells in LJ area are processed with the method. Log interpretation results are better, and hense provide not only an important basis for the development of pilot test area in LJ area, but also one method for effectively interpreting oil bearing property of glutenite reservoir.
