煤田采区三维地震资料解释方法及实际应用
|
摘要
为了保障煤矿生产的安全,三维地震勘探在煤田采区主要解决构造问题,因各地区地质情况的复杂程度不同,解释的准确度也有不同。随着计算机和物探技术方法的发展,煤田采区三维地震勘探资料的高信噪比、高分辨率为地震资料的精细解释提供了可能。笔者利用小波分析技术、方差体技术、图象处理等多种方法,结合已知采区的实例,对小断层做了精细构造解释,提高了三维地震资料的构造解释的精度。
ABSTRAC In order ensure the safety production of coal mines,three-dimensional seismic exploration in coal mine is mainly to solve problems of geological structures.The accuracy of data interpretation differs due to different geological conditions.With the development of computer and geophysical techniques,the high signal/noise ratio and high resolution of 3D seismic data makes it possible for detailed interpretation.In this paper,based on examples of known mining area,we use wavelet analysis,variance body techniques,image processing,and other methods interpret small fault in detail.As a result,the accuracy of interpretation is improved.
