摘　　要：甘肃省张掖市山丹县LS勘查区具有较好的找煤前景,为了寻找煤炭资源并对勘查区是否有进一步地质工作价值做出评价或总结,对该区进行了二维地震勘探。勘查区地震地质条件复杂,地震数据采集前,参考邻区采集参数,做了井深、药量、井组合等激发参数试验,确定了该区的数据采集方法,保证了原始数据的可靠性。利用静校正、叠加、偏移、速度分析等地震处理技术,获得了较好的地震时间剖面,并通过人机交互地震解释系统对地震资料进行分析解释,取得了较好的效果,达到了预期的目的。LS prospecting area of shandan county,zhangye city in gansu province has a good prospect for coal exploration,in order to find coal resources and evaluate or summary the exploration area for further geological work value,its has carried on the 2D seismic exploration to the area. Because of complex seismic geological conditions in exploration area,referring to the adjacent regions acquisition parameters,the excitation parameters such as well depth,dosage,well combination were tested before seismic data acquisition,identified the data acquisition method,ensure the reliability of the original data. Using seismic processing technology such as static correction,superposition,migration,velocity analysis,acquired good seismic time profile,and through the human-computer interaction seismic interpretation system to analyze the seismic data,achieved good results and desired purpose.
