最近二十年地震勘探技术的发展和取得的成就,原则上已消除了人们对地震方法能否研究岩性和直接找油的疑问。对解决途径和具体应用目标的探讨和试验已列入议事日程。首要的问题是确定利用什么类型的波(决定勘探方法)和选择最有效的地震参数。文献上讨论了反射波、折射波(首波、屈折波)、透射波等的应用,也讨论了各种参数:振幅、波形、反射系数、各向异性、吸收、纵波横波速度及速度比值,还有散射参数等。其中一些可称为直
The development and achievements of seismic exploration technology in the last two decades have, in principle, eliminated any doubt that seismic methods can be used to study lithology and find oil directly. Discussions and experiments on solutions and specific application goals have been put on the agenda. The first problem is to determine what type of wave to use (determining the method of exploration) and to choose the most effective seismic parameters. The literature discusses the use of reflected waves, refracted waves (first wave, flexural wave), transmitted waves, etc. Various parameters are also discussed: amplitude, waveform, reflection coefficient, anisotropy, absorption, longitudinal S-wave velocity and velocity ratio, There are scattering parameters. Some of them can be called straight
