摘要(Abstract)：
针对海拉尔盆地储集层岩块含量高、储层物性变化大等特点 ,选用优化测井方法进行处理解释。首先根据海拉尔盆地实际地质分析资料建立了多矿物双水解释模型 ,采用此模型并选用多条测井曲线 ,分别建立测井响应方程 ,然后利用优化测井解释方法计算出岩石骨架成分与储层参数 ,达到了对储层储集性质及流体性质精确解释的目的。对该区多口井的处理结果与实际岩心分析及试油资料的分析对比结果表明 ,建立的测井解释模型与方法先进、合理、可靠 ,计算的储集参数精度较高 ,取得了很好的应用效果。此外 ,根据岩相特征与实际取心资料建立了岩相划分标准 ,进行了测井相的划分。
According to the characteristic of high lithologic mineral content and more variety of physical properties in different blocks of reservoir in Hailaer Basin, optimization log interpretation method is used to process and interpret well logging data. On the basis of actual geologic analytical data, multi mineral dual water interpretation model is established. With this model the log response equations are set up on several logging curves, then rock matrix content and reservoir parameters are calculated by using optimization log interpretation method, from which reserving characteristic and fluid type of reservoir is accurately evaluated. The processing results of a number of well logging data agree well with those of core data and well testing data, the result of which shows that the established models and methods are advanced,reasonable and reliable, the precision of the computed reservoir parameters is high and the application results are good. Furthermore, on the basis of the characteristic of lithofacies and core data, the criterion of lithofacies identification is established and lithofacies on many wells is given by using logging data.
