【摘要】：地震勘探技术是一种重要的物探技术,在煤田地质中的应用越来越广泛,精度也越来越高。本文针对新疆哈密沙尔湖东部二区(研究区)前期地质资料匮乏,通过利用二维地震野外实验、数据采集、数据资料分析等工作,初步查明研究区覆盖层厚度、底板深度、主要煤层赋存范围及厚度变化趋势、基本构造轮廓,了解研究区构造复杂程度,控制可能影响研究区划分的主要构造,为研究区今后开展地质钻探布孔提供参数孔和找煤孔孔位,可有效的降低研究区勘探费用。在二维地震应用研究过程中,根据研究区地表、浅层条件差,深部煤层变化大等因素,合理采用野外数据采集方法,并通过道编辑、野外静校正、反褶积、自动剩余静校正等多种资料处理技术措施,使获取的时间剖面质量得到明显改善,为沙尔湖矿区乃至哈密地区开展煤田地质勘查工作提供一定的原始数据资料和应用借鉴。
[Abstract]:Seismic exploration technology is an important geophysical technique, which is more and more widely used in coalfield geology, and its precision is getting higher and higher. In view of the lack of early geological data in the second area (study area) of eastern Hamishaer Lake in Xinjiang, the thickness of the overburden and the depth of the bottom plate in the study area are preliminarily determined by using the work of two-dimensional seismic field experiment, data acquisition, data analysis, etc. The main coal seam occurrence range and thickness change trend, basic structure outline, understand the structural complexity of the study area, control may affect the main structure of the study area division, In order to provide parameter hole and coal hole location for geological drilling in the future, the exploration cost in the study area can be reduced effectively. In the process of two-dimensional seismic application research, according to the factors such as poor surface, shallow layer condition and great change of deep coal seam, the method of field data acquisition is reasonably adopted, and through channel editing, field static correction, deconvolution, etc. Automatic residual static correction and other technical measures of data processing can obviously improve the quality of acquired time profile and provide some original data and application reference for the development of coalfield geological exploration work in Shaerhu mining area and even Hami area.
