二维地震勘探在伊南煤田伊昭井田的应用

在地震地质条件不利的情况下,确定了合理的野外数据采集方法;根据二维地震的目的任务,运用了合理的数据采集方法,采用了较好的技术措施解决了地震资料处理及解译中存在的技术难点,包括静校正问题、干扰波的去除、分辨率的提高、波组分析、层位标定、断点解释等。在覆盖层厚度、煤层底板、煤层露头、构造解释、火烧区推测等方面取得了较可靠的勘探成果,为后续全井田勘探布局发挥了指导性作用。

Application of Twodimensional Seismic Exploration in Yizhao Coal Well of Yinan Coal Mine

Under unfavorable seismic geological conditions, reasonable method for collecting field datas has been determined. According to the purpose of 2D seismic data acquisition, by using reasonable data collection method and adoptint good technical measures, technical difficulties of seismic data processing and interpretation have been solved, including static correction, removing interference waves, improving resolution, wave groups analysis, horizon calibration and breakpoint interpretation. Reliable results have been gained in the exploration of overburden thickness, coal seam floor and coal seam outcrop, structural interpretation and buring area conjecture. It will play a guiding role for the exploration layout in the whole minefield .
