摘要
随着可控震源电控箱体技术的不断发展,可控震源交替扫描技术在西方地球物理公司中得到了广泛应用, 但国内该项技术应用较少。在常规交替扫描的基础上,发展并形成了可控震源高效交替扫描(交替扫描)技术, 该技术与常规交替扫描作业方式相比可提高效率30%,与单套震源施工方法相比可提高效率67%,有较大的推广应用价值。
With the development of electrical cabinet of vibroseis, flip-flop sweep technique has been widely adopted in Western geophysical companies. But in China this technique is seldom used. This paper develops a highly effective flip-flop method on the basis of conventional flip-flop method. The new method can greatly increase operation efficiency, more than 30% compared to conventional flip-flop sweep, and more than 67% compared to single vibroseis in operation.
