地震多参数油气预测方法及应用研究

The application of the seismic multiparameter oil-gas prediction method

地震多参数综合油气预测方法是一种基于地震数据计算储层段地震资料的富氏谱、功率谱、自相关、自回归和振幅等35种特征参数,并经广义线性分类,以实现油气异常圈定的方法技术。该方法的客观性较强,具有很高的可信度。经过碎屑岩储层、碳酸盐岩储层以及火山岩储层的预测和识别检验,具有较好的应用效果和广泛的市场价值,适应了油公司勘探开发的需要。

Seismic multiparameter oilgas prediction method is based on thirtyfive characteristic parameters such as Fourier spectrum, power spectrum, autocorrelation, autoregression and amplitude, and applied to the delineation of oil and gas anomalies according to general linear classification. The method is relatively objective and highly confident, and thus successively applied to the prediction and recognition of the clastic rock, carbonate rock and volcanic rock reservoirs. Due to its merits of wide application and great economic values, the method may well meet the needs of the exploration and development for petroleum companies.
