摘要
通过对轨道式可控震源的理论分析和激发原理的探讨,并结合实际资料,开展了轨道式可控震源井间地震资料的预处理研究;提出采用极化波分解及坐标系统旋转等方法,使轨道式可控震源井间地震资料的信号记录与常规井间地震资料保持一致。应用该方法对胜利油田垦71实验区轨道式可控震源的井间地震实验资料进行了处理,资料品质有了很大的改善,成像精度得到了提高。
Preconditioning for crosswell seismic data from orbital vibrator was studied based on an analysis of principles of orbital vibrator and its exciting mechanism.It is proposed to transform seismic data from orbital vibrator into conventional ones with decomposition of polarization wave and rotation of coordinates. This method has been applied in the data processing in Ken 71 pilot survey area in Shengli Oilfield.
