| 摘 要： | 本文就新疆哈密地区煤田三维地震工作，讨论了戈壁滩区三维地震工作实施的难点及采用的技术措施，并结合戈壁滩区采集的地震资料的特点对资料处理流程中的叠前去噪、静校正和三维偏移提频处理给予了重点关注.本次勘探表明在戈壁滩复杂地质条件区，利用“专用钻机成孔、高迭加次数、小炮检距、高频组合接收”采集技术，可获得较好信噪比的原始资料，经过精细处理和综合对比解释，地质成果良好.

| Abstract: | According to 3D seismic wave exploration for coal mineral in Xin-jiang desert area, the paper discusses the difficulties to execute 3D seismic exploration and the techniques to solve these problems. The paper also shows that we should pay more attentions to some of the data processing procedures for the data collected in desert area, such as noise removal for prestack data, static correction, and processing for picking up high frequency signals after 3D migration. The work in this paper shows that the high quality data can be collected in desert area with some special techniques, e.g. special drill equipment, more stacking numbers, short offset, combination high frequency receivers, and the geology interpretations for seismic exploration are reliable after high resolution data processing and conjunction comparison. |
