能量差法拾取直达波初至的应用研究
|
摘要
初至时间是地震勘探资料处理中一个很重要的参数,能否准确、快速地拾取地震记录中的初至对地震资料处理至关重要。地震记录上的初至波往往是由两种或多种不同类型的地震波组成,传统的能量比法拾取的初至参数往往由直达波和折射波的初至时间组成。在基于能量比法自动拾取地震初至的方法原理上,笔者提出一种新的初至拾取方法,即能量差法。实践表明,能量差法能有效地克服折射波的干扰,较为准确地获得直达波的初至,确保初至参数的统一性。
First break time plays a very important role in seismic processing.Whether it can pick up the first break time on the seismic record quickly and accurately or not influence the data processing.The first break time on seismic record usually consists of different kinds of seismic wave.The first break parameter picked up by the traditional method of energy ratio is often composed of the first break time of direct wave and refracted wave.On the foundation of the first break time picking method based on energy ratio,the author puts forward a new method based on energy D-value.The study shows that method based on energy Dvalue can effectively overcome the disturbance of the refracted wave,and pick up the first break time of direct wave to ensure the unity of first break parameter.
