观测系统与一般的共深度点法差别不大,在陆地勘探工作中,炮点稍微偏移于检波器大线,平均偏移不超过50米。不需将炮点位置排列成严格的图形,因而三维野外观测系统可灵活多变,有利于绕过障碍。在海上勘探中,使用了两组相同的气枪组合;借助于舷外铁架,将两组气枪固定在船的左、右舷上,相距40米。气枪组合交替爆发。沿穿过震源和接收器的直线进行资料处理。利用紧挨着记录的所有的野外道,我们
The observing system is not much different from the common co-deep point method. In the land exploration work, the shot point slightly deviates from the geophone line with an average deviation of not more than 50 meters. There is no need to arrange the shot locations in strict graphics, so the 3D field observation system is flexible and helps bypass the obstacles. In marine exploration, two identical sets of airguns were used; two sets of airguns were fixed on the left and starboard sides of the ship at a distance of 40 meters by means of an outboard steel frame. Airsoft combo broke out alternately. Data is processed along a straight line passing through the source and receiver. Take advantage of all the wild tracks recorded next to us
