Abstract:The ground survey of 3D seismic exploration is quite different from that of 2D seismic exploration because of its adoption of modern electronic computing technique, Computation, adjustment, check, printing and map compiling are automatically performed. The only work for the surveyor is to set up correct marks and to take necessary firsthand data, such as azimuth, distance, elevation, instrument level and so on, Field computation is unnecessazy. It is also unnecessary for surveyors to survery all lines in a 3D seismic exploration area with instrument in the field. Some lines are positioned with instrument in the field, and the others by interpolation. There are many ground survey methods used in 3D seismic exploration; however, whatever method we use, the technical specifications must be met.
