三维地震技术为资料的采集和处理提供了足够密度的地下界面采样点。这就可以通过三维波动方程偏移来研究和适当地显示原来的垂直图象。一般小格网要求每四分之一个波长必须有一个采样点。三维地震方法的特点: 显示反射图象原来的水平和垂直位置。消除绕射同相轴。恢复因散射影响而被削弱了的信号强度。由于增加了控制点的密度,从而得到更为精确的同相轴。
Three-dimensional seismic technology for the acquisition and processing of data to provide a sufficient density of the underground interface sampling points. This makes it possible to study and properly display the original vertical image by the three-dimensional wave equation shift. A typical small grid requires that every quarter wavelength have a sampling point. 3D seismic method features: Display the original horizontal and vertical position of the reflection image. Eliminate the diffraction axis. Restore the signal strength weakened by the effects of scattering. As a result of increasing the density of control points, a more accurate phase axis is obtained.
