煤田地震勘探地堑构造复杂区资料处理效果分析
|
摘要
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,断层倾角较大,采集的地震资料干扰严重,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,论证和分析了在狭长地堑复杂地区地震资料处理的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,提高了地震成像精度,从而达到提高煤田地震勘探水平,准确寻找煤炭资源的目的。
With the continuous improvement and development of coal exploration technology,seismic exploration gradually develop in the complex mining area.Due to the complexity of the surface condition,larger fault dip,serious interference of seismic data acquisition,processing large amount of static correction,resulting in lower signal-to-noise ratio and resolution of seismic data,and seriously affect the accuracy of the data interpretation.In this paper,taking Shulan coal field as an example,through the demonstration and analysis of the complex regional seismic data processing on all aspects of the method,means and measures,the final high signal-to-noise ratio,high-resolution seismic data,seismic imaging accuracy,improved level of coalfield seismic exploration and the purpose of looking for coal resources accurately.
