三维地震法是一种不同的汇集和显示地震资料的方法。与在一条剖面线之下表示地层界面的方法不同的是,三维显示给出从最浅反射界面到地震所能发现的最深反射界面的一个面积图形。在野外用十字排列获得资料,对每一反射界面可以得到多于2000个均匀分布的深度点。十字排列的几种形式可给出相同界面的复盖,而又提供汇集资料的灵活性。由于复盖稠密,这种方法对于要求最详细的问题—如开采问题——极为适宜。通常作三维资料的显示是视觉的,它移动地展示来自复盖达4平方哩地面范围内出现的波前。从这个动态展示中,每个反射界面的平均速度、倾向和倾角可以算出。这种方法专门用来识别断层和确定断向 3D seismic method is a different method of assembling and displaying seismic data. Unlike the method of representing the formation interface below a section line, the three-dimensional display gives an area graph of the deepest reflection interface found from the shallowest reflection interface to the earthquake. In the wild with cross-array access to information, for each reflection interface can be more than 2000 points evenly distributed depth. Several forms of crosses give the same coverage of the interface, yet provide the flexibility to gather data. Due to the dense cover, this method is extremely suitable for the most detailed problems - such as mining problems. The usual visual display of three-dimensional material is moving to show the wavefront emerging from the coverage of up to 4 square miles of ground. From this dynamic display, the average velocity, inclination, and tilt of each reflective interface can be calculated. This method is designed to identify faults and determine breakouts
