可控震源高效地震采集技术研究及应用

The research on vibrator high efficient simulation technology and its application

可控震源同步滑动扫描方法是将滑动扫描技术、同步扫描技术和交替扫描技术相结合,以提高地震成像质量和采集施工效率为目的的一种高效地震采集方法。为了更好地应用这项技术,2013年在我国西部HS地区开展了观测系统设计、高效采集方法试验、高效采集特征噪声压制等几个方面的应用研究,取得国内最高日产、最高时效、最高平均日产3项记录。将该方法应用于HS地区复杂山前带三维地震勘探,有效提高了该地区地震剖面的成像质量。

Efficient synchronous slip sweep method is an efficient seismic acquisition method that combines vibra tor slide sweep technology,synchronous sweep technology and alternate sweep technology,aimed to improve the seismic image quality and construction efficiency.Since it is widely used in overseas market,in 2013,a key task test is launched in HS area from the aspects including geometry design,efficient construction method test,acquisition characteristics noise suppression and so on.The method was used for the first timein large-scale applications of 3D seismic exploration in the western piedmont zone of HZ area that improves the seismic imaging quality in complex piedmont zone and gets significant results.
