高精度卫星照片在民和黄土山地勘探中的应用
Application of High-precision Satellite Pictures in Exploration of Minghe Loess Mountainous Region
【摘要】 该文对民和地震采集存在的问题进行研究,分析认为有效激发与合理的观测方式是获得资料的可靠保障。在采取三维观测的基础上,应用高精度卫星照片和DEM高程数据,为优选激发岩性、合理变观、优化表层控制点等参数提供依据。通过优化观测系统、优选炮点、精细表层调查与静校正的综合应用,民和三维勘探地震剖面品质有了大幅度提高,取得了较好的勘探效果。
【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.
