摘　　要：针对常规三维地震勘探对小构造和复杂构造分辨能力弱、对小断层识别精度差的问题。在地震数据采集中设计全方位观测系统、连续滚动,采用单点、小泡间距激发,单点、小道间距、全频带接收,高密度、高覆盖次数采集,使野外数据采集质量大幅度提高;在室内采用配套的高精度数据处理技术和针对资料特点的一系列精细解释技术。通过地震采集、处理和解释技术的合理应用,形成一套了完整的煤炭高精度三维地震勘探技术。该技术使地震勘探对小断层、微小构造和复杂构造的勘探能力明显得以改善,极大提高了地质成果的精度。In view of the weak resolution of small structures and complex structures in conventional 3 D seismic exploration,the identification accuracy of small faults was poor.In the seismic data acquisition,the omni-directional observation system was designed and continuously scrolled,the single-point,small-bubble excitation,single point,trail spacing,full band reception,high density and high coverage acquisition were used to greatly improve the quality of field data acquisition.The high precision data processing technology and data for supporting a characteristic a series of fine interpretation technique in indoor.Through the rational application of seismic acquisition,processing and interpretation technology,a complete set of high precision 3 D seismic prospecting technology has been formed.This technique significantly improves the exploration capability of seismic exploration for small faults,small structures and complex structures,greatly improving the accuracy of geological achievements.
