摘要

在山前砾石覆盖区或浅层卵砾石发育区,获得较高信噪比的地震资料是目前煤田地震勘探所面临的难题之一。由于炸药震源成孔困难,且难以获得理想的可用于生产的野外原始地震资料,而大吨位可控震源具有能量大、技术参数精确可控、震源一致性高等优点,由此弥补了该类地区炸药震源的不足。通过对不同吨位可控震源在相邻区块采区勘探中的应用效果分析,说明了在类似勘探区只有使用大吨位可控震源才能取得较高质量的地震资料。
In the piedmont area or shallow gravel covering developed area,how to get a higher noise ratio signal of seismic data currently challenged coalfield seismic.As it was difficult to form explosive source into a hole and so was getting a good field for the production of the original seismic data,and the large tonnage vibrator owned the advantages of large energy,technical parameters accurately controlled and focal high consistency,which made up the lack of such dynamite source region.Based on application effect analysis of different tonnage vibrator in the adjacent block mining exploration,the thesis illustrated that only using big tonnage vibrator can get high quality seismic data in similar exploration area.
