地震特征参数与测井参数相结合识别油气层

用奇异值分解法提取并分析地震特征参数（即地震波的频率参数，振幅参数，相位参数，衰减因子），研究地震特征参数在油，气，水，干地层的变化规律，然后结合测井参数与油，、气，水，干地层的变化规律，应用数理统计方法以及ＢＰ神经网络，把已知ＣＤＰ道号的测井参数推广到未和的ＣＤＰ道号，以此预测油气层分布。

Integrating Seismic Characteristic with Log Parameters for Identifying Oil and Gas Zones

Such seismic characteristic parameters as frequency, amplitude, phase and attenuation factor of seismic wave are extracted and analysed by RRP (Robust, Reliable and Precise) method. And then their changing law in oil, gas, water and dry beds is derived. Integrating log parameters with seismic characterstic parameters and using the changing law of seismic parameters, mathematical statistics method and BP network technique, the log parameters in the known CDP track are introduced into the unknown ones, thus, predicting the hydrocarbon distribution.
