碳酸盐岩薄储层横向预测方法

在对四川盆地川东大天池构造带的石炭系地层进行薄储层横向预测时.提出了一套模式化分析方法。此法以建工的储层序列地质模式为基础.利用测井曲线垂向分辨率高的特点.采用下同频率子波的合成地震记录,把地质、测井和地震资料有机地结合起来进行综合解释,对石炭系储层的顶、底界面及储层沉积微相进行了标定;同时研究了储层的物性变化。在该区,用上述方法对碳酸盐岩薄储层进行早期横向预测,取得了显著的地质效果。

Lateral prediction method for thin carbonate reservoir

Pattern analysis method was used to make lateral prediction of thin reservoir in Carboniferous system at Datianchi structural belt in east Sichuan. This method means that we comprehensively interpret geological.logging and seismic data to determine the top,bottom,sedimentary micro facies and physical characteristic variation of Carboniferous reservoir by adopting the geological pattern of reservoir series, vertical high resolution of logging trace,and synthetic seismograms of wavelets whose frequencies are different from each other. This method was applied to early lateral prediction of thin carbonate reservoir in the area,resulting in satisfactory geological effect.
