煤田采区三维地震资料精细解释方法及应用

三维地震勘探在煤田主要解决构造问题,因各地区地质情况的复杂程度不同,虽然已经过十多年的发展,但构造解释的准确度也有不同程度的差异。随着计算机技术发展和石油物探方法的引进,煤田采区三维地震勘探资料高信噪比、高分辨率为精细解释提供了可能。本文利用小波分析技术、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构造解释的精度。

Detail Structural Interpretation Methods and Application of 3D Seismic Data in Coal Mining Area

3D seismic exploration in the coal field is mainly used to solve the structural problems of the region because of the different complexity of the geological conditions,though has been more than 10 years of development,but the accuracy of the structural interpretation also have different degrees of difference.With the development of computer technology and the introduction of oil geophysical methods,coal mining area of 3D seismic exploration data of high signal to noise ratio and high resolution provide the interpretation of a possible fine.By using wavelet analysis,coherency cube technology,image processing,and other methods,mining area with known examples of small faults have a fine structural interpretation,improved the accuracy of 3D seismic structure data interpretation.
