【摘要】 勘探实例表明,在丘陵砾石区、山区等条件复杂地区开展采区三维地震勘探应综合考虑仪器、震源、钻机、激发因素、接收方式、震源组合、观测系统等施工要素,通过实验获得最佳施工参数。炸药震源是山区的最好激发方式,通常以单深井或多井组合为主,激发岩性以含水岩石为佳。应通过对比实验,选取适合勘探区资料特点的处理模块和参数。要充分利用地质体在地震时间切片、顺层切片、方差体切片上的识别特征,以提高解释成果的可靠性。更多还原

【Abstract】 Prospe cting examples have demonstrated that,operational factors of instrument,source,drilling rig,shooting factor,receiving mode,source combination and field setup should be comprehensively taken into account in complex conditions of gravel hilly and mountainous areas,and gotten optimal operational parameters through tests.Explosive energy source is the best shooting mode in mountainous areas,and gives priority to single deep hole and multiple holes commonly,shotpoint is best in water-bearing beds.Processing modules and parameters should be selected through comparative tests and adapt to prospecting area data characteristics.Take full advantage of geologic body recognition features on seismic time slices,bedding slices and variance cube slices to improve reliability of interpretation results.更多还原
