一种基于多条件约束测井有效储层解释方法

为了解决测井有效储层自动解释精度不高的问题,提出了基于泥质含量、含水饱和度以及孔隙度多成果曲线拟合,建立有效储层划分条件、层内曲线特征值提取条件以及储层有效厚度下限约束条件,实现多条件约束测井有效储层精确解释的方法。南海西部油田测井解释中的应用结果表明,该方法具有分层精度和自动化程度高的特点,与以前的解释结果相比精度有了较大的提高。

 In order to improve the accuracy of automatic logging interpretation for effective reservoir,we present a new method to realize multi-constrained log automatic interpretation for effective reservoirs,which is based on multi-log fitting (shale content,water saturation and porosity),establishes the constraints for effective reservoirs classification,interlayer log feature value extraction and the lower limitation of reservoir effective thickness.The application on the log interpretation of an oilfield in the west of the South China Sea shows that the method is characterized by high classification accuracy and high automation degree;meanwhile,the interpretation precision has been greatly improved.
