摘要
随着多波勘探的发展,横波已越来越多地应用在实际勘探生产中,横波速度参数研究对于指导勘探是十分必要的。笔者利用纵横波VSP测井得到的纵横波速度,根据最小平方误差建立的速度模型,建立了济阳坳陷的纵波、横波、转换波速度参数,应用转换波速度参数提高了盐家地区的多波资料解释精度;利用多种资料总结出纵横波速度关系,为本区今后开展多波勘探提供基础资料。
Using the velocities of P wave and S wave obtained from P wave and S wave VSP logging and based on the velocity model constructed from the least squares error, the authors have established the velocity parameters of P wave, S wave and converted wave in Jiyang area. With the converted wave velocity parameter, the interpretation precision of multiple wave data in Yanjia area has been raised. The velocity relationship between the P wave and the S wave deduced from various data provides basic data for the performance of mutiple wave exploration in this region.
