针对G3i仪器震源高效采集过程中SPS辅助数据的自动整理
|
摘要
随着"两宽一高"概念的不断推广,可控震源技术的不断革新,超万道接收的大型三维地震勘探也广泛应用。对于一线技术人员而言,随之而来的便是数据量的不断增大以及数据处理任务的越发繁重。通过对近年的"两宽一高"三维项目的研究,首先分析了现场SPS整理过程中所出现的格式异常等问题;然后总结SPS整理流程,结合自身经验,利用Python程序设计语言对超万道SPS整理实现了自动化;最后利用近年"两宽一高"三维项目采集中原始SPS文件对自动化软件进行测试,取得了良好的效果。
With the popularity of the"2 W-1 H"(wide-band,wide azimuth and high-density)technique and the continuous innovation of vibroseis technique,large 3 Dseismic surveys received by more than 10,000 channels are also increasingly popular.For the front-line technicians,the data volume is increasing and the data processing task is becoming more and more onerous.Through the recent research on the"2 W1 H"3 Dprojects,the paper analyzes the format abnormality and other problems in the field SPS finishing process.Then,the process of SPS arrangement was summarized,and the Python programming language was used to automate the process of SPS arrangement.At last,the original SPS files from the"2 W1 H"projects in recent years were used to test the automatic software,and good results were obtained.
