【摘要】 针对新疆塔城地区某煤矿三维地震勘探区戈壁地表复杂、目的层埋藏浅等地质条件,阐述了在野外数据采集、室内资料处理及资料解释的不同阶段所采用的相应技术措施和取得的地质效果。勘探结果表明:在目的层较浅的复杂地表区,采取小CDP网格、高覆盖次数、现场监控、精细处理、人机交互辅助解释和多元地质信息分析等技术手段,可以获得勘探精度较高的地震地质成果。更多还原

【Abstract】 In view of such phenomena as complex surface conditions,shallow target formation depths and overlying Gobi and hills encountered by 3D seismic exploration in a certain coal mine of Tacheng area,Xinjiang,this paper deals with some corresponding technical measures and their geological effects at different stages of field data collection,data processing and data interpretation.Exploration results indicate that seismic geological results with relatively high exploration precision can be obtained under complex surface conditions in Gobi area by using such techniques as small CDP grid,high covering numbers,in situ monitoring and control,fine processing,man-computer interaction supplementary interpretation system and multivariate geological information analysis.更多还原
