摘要
宽线地震技术是一种地震勘探方法 ,它采用的是一种特殊的三维观测系统 ,特别适合在一些障碍区内施工。本文介绍的这项技术主要包括 :研制出新型的水中钻井平台 ,解决了水中激发问题 ;精心试验 ,掌握了不同类型检波器之间的相位差别 ;采取一些特殊的处理方法 ,解决了新老资料在采集方法和资料品质上的差异。综合应用这些技术有效地填补了以往勘探地震剖面上的资料空白。
As one of the seismic prospecting methods,wide line seismic technique adopts a special 3D spread observation system,especially suit able for working at some obstacle regions By this technique,the problem of shotting in water is solued with a new drilling platform,the phase differences of variety of geophones are held by passing meticulously tests,and it is distingaished of exploration method and data quality between new and old seismic data by adopting special processing methods
