摘要
由于转换波静校正是一个新的课题,没有成熟的方法可以借鉴,常规用于纵波静校正的许多方法,很难照搬到转换波处理当中,所以,需要从最基本的表层资料采集入手,寻找一种系统的转换波静校正方法。微测井一直是解决纵波勘探表层问题最直接最有效的表层调查方法,同样利用横波震源,也可以进行横波微测井采集。从横波资料的表层调查和应用,转换波静校正量的计算和应用2个方面,对横波微测井转换波静校正方法进行了介绍,通过实际资料的处理,说明该方法有一定的实用性和灵活性,并有一定的推广价值。
Static correction of converted waves is a new research top- ic that no proven method can be used for reference.Many methods for P-wave statics cannot be used for converted wave data processing.Static methods for converted wave need to be developed systematically from near surface investigation.Up- hole shooting is a mostly direct and effective method.Similar- ly,shear wave uphole shooting can be conducted using shear wave source.This paper discussed the investigation and appli- cations of near surface shear wave data as well as the calcula- tion and applications of converted wave statics.The feasibility of the method is demonstrated with real data.
