随着煤田勘探技术的不断提高和发展,地震勘探逐步进入复杂地区。由于地表条件复杂,地层倾角较大,使得地震采集干扰严重,处理静校正量大,从而导致地震资料信噪比和分辨率降低,严重影响资料解释的精度。本文以舒兰煤田为例,采用理论与实践相结合,详实的分析和研究了煤田领域在狭长地堑复杂地区地震资料采集及处理各个环节上采用的方法、手段和措施,最终得到高信噪比、高分辨率地震资料,为地震报告的提交提供有利的数据保障,从而达到提高煤田地震勘探水平的目的。
With the continuous improvement and development of coalfield exploration technology, seismic exploration gradually enters complex areas. Due to complex surface conditions and large dip of strata, the interference of seismic acquisition is serious and the static correction amount is large. As a result, the signal-noise ratio and resolution of seismic data are reduced, which seriously affects the accuracy of data interpretation. Taking Shulan coalfield as an example, this paper combines theory with practice, and analyzes and studies the methods, measures and measures adopted in all aspects of the seismic data collection and processing in the complex area of long and narrow graben in the field of coal mining in detail. Finally, Compared with the high-resolution seismic data, it provides favorable data protection for the submission of seismic reports so as to achieve the purpose of improving the seismic exploration level in coalfields.
