浅地层剖面数据的自动精处理方法研究

High Precision Data Processing Flow of Sub-Bottom Profiling

针对浅地层剖面数据依赖人工处理工作量大、成果精度不高的现状,给出了一种高精度自动化处理方法。该方法包括原始数据解码、浅剖图像生成、多次波压制、噪声消除、海底线跟踪、层界提取等过程。与原人工处理方式相比,浅地层剖面数据的自动处理方法有效提高了数据处理效率,其层界提取结果得到实验验证。

As to the problems of sub-bottom profiling processing,such as depending too much on manual work,big workload and low precision,a automatic and high accuracy method is proposed in this paper.This method consists of the decoding of SEG-Y files,the production of sub-bottom images,multiple attenuation,noise attenuation,seafloor tracking and layer extraction.Compared with the original manual processing,it improves the efficiency of data processing effectively,and it has been verified by experiment.
