摘要
针对我国东北地区地质构造特征,在煤田地震勘探资料解释工作中,解释后的水平叠加时间剖面,需要进行时深转换;在时深转换作图过程中,依据不同地质模型,采用各自地质模型的综合速度曲线,对水平叠加剖面采用分层作图,使地质层位空间二维归位后,误差小、位置准,从而可提高地震勘探资料解释精度。
Aiming at the structure characteristics of geologic layer in the region of North China,in the work of the coal seismic prospecting data interpretation,the seismic level folds time sections which have been interpreted need to convert from time to depth;in procedure of converting the level folds time section data,from time to depth,according to different geologic models,using respond compositive speed curves to the different geologic layer,with minimum of the error margin make plots by layer,to get the real depth of the geologic layer position in two-dimensional space,so that to improve the precision while converting the level folds time sections to geologic layer depth.
