二维地震勘探在找煤中的应用
|
摘要
随着地震勘探技术的快速发展,二维地震勘探在找煤工作中具有越来越重要的指导作用。豫中南某煤预查区在20世纪50年代就曾做过煤田预测工作,但由于覆盖层较厚,当时技术手段单一、仪器落后、方法陈旧、资金短缺等原因,对深部构造认识不清,找矿未能有大的突破,但从以往资料分析认为该区有较好的成煤岩系存在,找煤前景较好。本文通过地震勘探在该区找煤中的应用实例,说明运用现代地震勘探技术能够获得高分辨的地震资料,很好地指导了钻探验证孔的布设和后续设计工作的开展。
With the rapid development of seismic exploration technology,the method of 2D seismic detection plays a much more important role in coal exploration.In the 1950s,a coalfield in the central south of Henan province was forecasted,but there was no breakthrough in exploring coal because of some reasons such as the thick layer,lack of advanced technology,old methods,short of money and so on.However,by analyzing the previous data,it has a good coal-bearing formation in this field.Based on the examples of seismic exploration in this field,the paper concludes that using the modern seismic exploration techniques can acquire high resolution seismic data,which guides the layout of drilling holes and the following tasks.
