摘    要:通过对地震勘探数据采集方法的理论分析及现场试验,提出了提高地震勘探分辨率的采集方法。从震源、检波器及仪器参数的选择等几个方面进行了分析和试验,并讨论了其对提高地震勘探分辨率的作用。通过实际应用效果分析,提出的提高地震勘探分辨率的措施是有效的、可行的,可使地震反射信号通带由原来的200Hz提高到300-400Hz,进一步提高了地震勘探对小构造的分辨能力。

关 键 词:数据采集  仪器参数  分辨率  反射信号  地震勘探  震源  检波器

Abstract:Through theoretical analysis on acquisition methods and field tests, a method of increasing seismic exploration resolution is presented. It makes some analysis and experiments from the aspects of seismic source as well geophone and instrument parameters choosing. The impact on increa sing the resolution of seismic exploration are discussed. By means of practical application and effect analysis, it has proved that the method of increasing seismic exploration resolution is both effective and feasible. The frequency band of seismic refec tion signal is increased from 200 Hz to 300~400 Hz, and the resolving ability of seismic exploration is increased further for small structure.
Keywords:high  resolution seismic exploration  exploration technique  data acquisition
