Abstract: High-productivity vibroseis techniques have been developing rapidly and been applied widely in the Middle East and Africa in pursuit of high productivity. This paper briefly reviewed the high-productivity vibroseis techniques such as Slip Sweep, Distance Separated Simultaneous Sweeping (DSSS), DSSS plus Slip Sweep, and Independent Simultaneous Sweeping (ISS), introduced key techniques developed by BGP, including geometry design, non-stake surveying, quality control, and harmonic attenuation, and finally presented the application effects of the techniques in seismic projects of BGP International.

Key words: high-productivity vibroseis, slip sweep, DSSS plus slip sweep, independent simultaneous sweeping (ISS), harmonic attenuation, non-stake surveying

摘要： 在国际油公司追求高效地震勘探及经济效益最大化的推动下,滑动扫描(SlipSweep)、滑动扫描同步激发(DSSSplusSlipSweep)等可控震源高效采集技术获到快速发展,并在中东、非洲等地区得到了广泛应用。文章介绍了滑动扫描、距离分离同步激发(DSSS)、滑动扫描同步激发、独立同步扫描(ISS)等可控震源高效采集技术的基本原理,以及观测系统设计、无桩号测量、现场质量控制、数据存储与转换、滑动扫描谐波压制和独立同步扫描邻炮干扰压制等可控震源高效采集关键配套技术,并且展示了这些技术在公司国际地震勘探项目中的应用情况及实际效果。
