可控震源高效采集异常代码分析及应对措施

Analysis of anomalous codes for vibroseis efficient acquisition and countermeasures

大道数可控震源高效采集是目前石油勘探市场主流的地震采集方法,对施工队伍而言,需要在保证质量的前提下追求效率最高。本文从提高生产效率角度出发,开展现场试验,深入研究和分析了造成异常代码出现的原因,并在此基础上提出了三项改善措施:减少震源联机频次;更换电台频段;开发废炮查询功能。通过这三项举措,有效降低了异常代码出现的次数,在降低废炮比率的同时提高了震源施工效率,对提速增效有着重要意义,可为其他类似可控震源高效采集项目提供借鉴。

Efficient acquisition of high count channels vibroseis is the mainstream seismic acquisition method in current exploration market,and for construction teams,the highest efficiency needs to be pursued with quality assurance.In this pa per,from the perspective of improving production efficiency,field tests were conducted to thoroughly study and analyze the causes of the appearance of abnormal codes,and three improvement measures were proposed on this basis:reducing the frequency of vibroseis linkage;replacing the radio frequency band;and developing the query function for waste cannons.Through these three initiatives,the number of abnormal codes appeared was effectively reduced,and the construction efficiency of the seismic source was improved while the ratio of waste cannons was reduced,which is of great significance to speed up and increase efficiency,and can provide reference for other similar vibroseis efficient acquisition projects.
