DETERMINATION OF THE MAJOR PARAMETERS IN 3-D SEISMIC DATA ACQUISITION

To select the proper acquisition parameters in 3-D seismic survey is a major premise for ensuring the quality of the final results. According to the actual situation of a prospect area,techniques for the major parameter determination ,such as the resolution (vertical resolution and horizontal resolution ), the maximum offset, the interval for directional sampling,the superposed width on the border area,etc. ,were worked out. Parameters for 3-D seismic acquisition in the prospect area were given.
