摘　　要：预测储集层一般所采用的叠后反演技术,是建立在常规处理的水平叠加数据和以自激自收为假设条件基础上的,这样的叠后反演剖面不能真实反映野外采集所记录的振幅随炮检距变化的特性,并损失了与炮检距关系密切的大量横波信息;而叠前反演又无法达到测井约束反演的分辨率。为此,可先进行叠前反演处理,在获得零炮检距资料后再进一步进行多参数测井约束反演,并采用中子伽马和自然伽马数据体进行交会处理的方法来解决高泥质含量的识别问题。该方法较好地解决了高泥质含量碳酸盐岩储集层横向预测问题,并在希望油田取得了较好的效果。In general,the post-stack inversion for reservoir prediction is made based on horizontal stacking data after conventional processing and the consumption of self excitation and self receiving.Such a post-stack inversion profile can not reflect the amplitude variation with offsets,and a lot of S-wave data that is closely related to the offsets are lost.And pre-stack inversion can not get logging constraint inversion resolution.Therefore,pre-stack inversion processing can be made at first to get zero-offset and then conduct multi-parameter logging constraint inversion.Using the crossplot processing of neutron-gamma logging and gamma ray log data can solve the problem of high shale content.By combination application of these methods,the carbonate reservoirs with high shale content can be well predicted laterally in Hope oilfield.
