塔里木盆地孔雀河地区多次波压制方法与效果

Method and Effect of Multi-wave Pressing in Kongquehe Area of Tarim Oilfield

针对孔雀河多次波的特点,应用稀疏PRT压制多次波方法,利用多次反射波的特征及其与一次反射波的差异,加强对数据的抛物线分离,更精确、更有效地实现了多次波的分离与压制,达到压制孔雀河地震资料目的层强多次波干扰,恢复弱有效反射的目的。

Io consieeration of the characters of multiple waves in Kongquehe area.The method of loose PRT multiple wave pressing is used to enhance the separation of data parabola by using multiple reflection waves and the difference of other inflection waves,by which the separation and press of multiple waves are implemented more accurately and effectively for the purposes of pressing interference of strong and multiple wave of seismic data and restoring the weak effective reflection in the target zones of Kongquehe area.
