摘要

在深海拖缆地震采集过程中,借鉴共CDP道集叠加技术,建立了共炮集叠加、超炮集叠加概念。此项技术可以作为深海拖缆采集中的质控手段,并及时发现和解决以下问题:①由于没有激发或通路断开、没有接收等原因造成的空炮;②某一缆接收出现问题或断排列等原因造成的空废炮;③周期或相位固定的细微干扰,如漏电等;④仪器串音等较为严重的干扰。
During offshore seismic streamer acquisition, the conception of common-shot-gather and supper-shot-gather stack can be built up by the aid of CDP gather stack technique, which can act as QC tool of offshore streamer acquisition, and discover and solve the following issues in time:①shot-gap resulted from not-shot or without receiving by channel cutoff; ②shot-gap or useless-shot resulted from appearing problem on receiving cable or spread cutoff; ③minor interference with period or phase fixed, for example, leakage; ④more serious interference like instrument crosstalk.
