摘要
地震反射波振幅与很多因素有关,地层厚度是影响地震反射波振幅的因素之一。本文介绍了消除地层厚度对薄层地震反射波振幅影响的方法,从而突出了地质因素在地震波振幅图上的反映,以利于地震波振幅平面图的解释,为寻找油气层及圈定油气边界提供依据。我们用实际资料制作了地震波振幅异常平面图,收到了较好的效果。
The seismic reflection amplitude deals with a wide range of elepignts. Formation thickness is taken as one of the factors affecting the seismic reflection amplitude. An approach to get rid of the effect of formation thickness on seismic reflection amplitude is advanced in the paper. Thus,it does highlight the geologic factors seen on the diagram of seismic wave amplitude so that it helps interpret the plan of seismic wave and provides a scientific basis for detecting oil/gas bearing reservoir and delineating the oil/gas boundary. Also,a plan of seismic wave amplitude anomaly is constructed. An appreciable result is achieved to this end.
