中国石油可控震源高效地震采集技术应用与展望

Application and outlook of vibroseis acquisition techniques with high efficiency of CNPC

讨论了目前国内外成熟的交替扫描激发、滑动扫描激发、滑动扫描同步激发和独立同步扫描激发这4种可控震源高效采集技术方法以及国外应用进展,深入分析了我国陆上可控震源常规采集现状;针对目前国内陆上地震采集存在的问题与面临的难点,从采集效率、采集成本、地震资料效果等方面对已经实施的交替扫描、滑动扫描等高效采集技术应用进行了剖析,对今后我国陆上不同地表、不同地下地质条件区域如何应用高效采集技术进行了展望。

Four vibroseis acquisition techniques with high efficiency including the flip-flop sweeping technique, the slip sweeping technique, the distance separated simultaneous sweeping technique, and the independent simultaneous sweeping technique, and their application both at home and abroad were discussed. The current state of China＇s conventional onshore vibroseis acquisition was analyzed thoroughly. For current problems and difficulties in domestic onshore seismic acquisition, flip-flop technique, slip technique and other high-efficiency acquisition techniques were analyzed in terms of acquisition efficiency, acquisition cost, and seismic effect, etc. How to apply high-efficiency acquisition techniques in onshore regions of different surface and subsurface geologic conditions in China in the future was prospected.
