摘要
单参数反演引起的反演结果多解性和层位标定的不确定性一直是影响复杂断块地区储层预测精度的两大难点 ,而多参数联合反演在一定程度上避免了多解性问题。本文通过细致而充分地研究多参数反演的关键技术——测井岩性特征技术 ,总结出一套多信息、多层次精确层位标定方法 ,并用实例说明了精确的基础分析工作是保证反演结果可靠性的关键。
The multi-solution of inversion by single parameter and layer-labeling uncertainty are two difficult points that restricted the precision of reservoir prediction in complex fault block zone,which can be avoided to a certain degree by using multi-parameter integrated inversion.The paper studied carefully and fully the key technique of multi-parameter inversion-logging lithologic characteristic technique and summed up a set of methods for multi-informational and multi-leveling,precision layer-labeling.Finally,it is showed by a case that precision basic analytic works are the key to ensuring the reliability of inversion.
