时频分析及其在松南地区的应用
The Application of Time-Frequency Analysis to Songnan Region
【摘要】 以地震资料与测井资料相结合 ,利用测井、地震联合反演方法进行地震资料高分辨处理 ,结合其频率特征在时间和空间上的变化规律来反映地质体的结构关系。由于构造运动的周期性及地层沉积的旋回性对应于地震资料的频率特征 ,因此地震波的频率变化可以反映沉积体的厚度及沉积颗粒的粗细。通过地震资料的时频分析特征的对应关系 ,进行构造层系解释 ,指导储层预测 ,为沉积分析提供可靠的依据
【Abstract】 Combining with log and seismic datum to make high resolution disposal, and reflect the geological structure of the cycle of construal mobility and stratigraphic sediment can reflect the frequently of seismic. So the change of seismic wave can reflect the thickness of sediment and the big and small of sedimental grain. Applying timefrequency analysis technigue, the authors research the constitutional sequencal body and the relationship between the cycle of sediment and the frequently of seismic, and explain constitution sequencal, and predict reservoirs. It can provide reliable proof for sedimental analysis.
【Key words】 timefrequency analysis; seismic and log inversion; constitution sequence analysis; sediment sequence analysis;
