可控震源在国内外地震勘探领域得到了广泛的应用。新疆准南煤田三维地震数据采集尝试采用了可控震源的激发方式。通过对驱动幅度、扫描频率、扫描长度、震源台数、震动次数等参数进行试验优选,确定了符合勘探区地震条件的激发参数组合,地震数据采集获得了良好的效果。通过对比勘探区以往炸药激发,可控震源激发提高了地震数据的分辨率与信噪比。同时可控震源还具有安全、环保、高效、经济等优势。
Vibrators are widely used in the field of seismic exploration at home and abroad. Three-dimensional seismic data acquisition in Zhunan coalfield in Xinjiang attempts to use excitation mode of vibroseis. Through the experiment and optimization of parameters such as driving amplitude, scanning frequency, scanning length, number of seismic sources and vibration frequency, the excitation parameters combination that meets the seismic conditions of the exploration area is determined, and the seismic data acquisition achieves good results. By comparing the previous explosives excitation in the exploration area, the control of seismic source increases the resolution and signal-to-noise ratio of seismic data. Vibrator also has the advantages of safety, environmental protection, high efficiency, economy and so on.
