【Abstract】 The problems existing in seismic acquisition in Minghe basin are studied. The analysis indicates that the ef-fective excitation and the reasonable observation system are reliable guarantees for obtaining data. Based on the three-dimensional observation, high-resolution satellite pictures and DEM altitude figures are used to provide basis for param-eters such as optimum excitation lithology, reasonable changing observation and optimum surface control point. Through comprehensive application of observational system optimization, preferred shot, fine superficial investigation and static calibration, the quality of three-dimensional exploration seismic profile in Minghe basin has great improvement, and good exploration effect is obtained.更多还原
