【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,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。更多还原

【Abstract】 In recent years,along with the development of the coal field exploration technology,the seismic exploration starts to get into complex areas.Due to the complex surface conditions and the great inclination of the stratum,the seismic acquisition is seriously interfered and the amount of statics correction becomes bigger,which leads to reducing the signal-to-noise ratio and resolution of the seismic data and affects the accuracy of the data interpretation.This paper,taking Shulan coalfield as an example,by combining theory with practice,analyzes detailedly the seismic data acquisition in the complex coal areas,describes how to deal with the method and measurement in the different process and finally obtains the high signal-to-noise ratio and high resolution seismic data,which provides the useful data for submitting the report about the earthquake.The goal of raising the level of coalfield seismic exploration is reached.更多还原
