中文摘要	为了提高沙漠区低信噪比地震资料的品质,从优化野外资料采集的激发方式出发,开展了小药量单井多次激发组合叠加方法试验。根据地质任务要求、工区表层结构条件和激发信号的优势频带宽度,通过多种激发因素的野外试验综合确定小药量单井激发的合理药量;针对克服小药量单炮能量不足,同时又利于压制干扰波的要求,对野外主炮点上小药量单井组合参数与井位布设进行合理的设计,并在后续的室内组合叠加处理时优选最佳炮数的小药量资料;通过小药量单井资料的组合叠加处理与分析,获得不同地表条件下一个主炮点上小药量单井多次激发应布设的最佳井数(激发次数)。方法试验和试生产的应用效果表明,小药量单井多次激发组合叠加技术较好地提高了沙漠区地震资料信噪比和分辨率。
英文摘要	In order to improve the quality of low signal-to-noise ratio seismic data in desert area,from the optimization of the way of shooting on field seismic data acquisition,we carried out the method experiment on array stack with multi-shooting records by smallcharge explosive in single borehole.According to the requirements of geologic task,as well as the condition of surface structure and dominant frequency band width of shooting signal,the reasonable quantity of small explosive in single borehole was synthetically determine by different shooting factors experiments in field.Aiming at overcoming the lack of energy by small-charge explosive in single borehole and meeting the demands for suppressing noise,we designed the reasonable array parameters for multi-shooting by smallcharge explosive in single borehole and well arrangement at the field main shot point;and then choosing the shot records of the optimal number of small-charge explosive in the next indoor arraystack processing.By analyzing on the array stacked records,we get the optimal number of small-charge explosive in single borehole at the one main shot point on different surfaces(shooting numbers).The method experiment and preproduction application indicate that the technique of array stack with multi-shooting records by small-charge explosive in single borehole improves signal-to-noise ratio and resolution of seismic information in desert.
