轨道式可控震源井间地震资料预处理方法研究

Study on the preprocessing cross-well seismic data of tracked vibroseis

在对轨道式可控震源理论分析和激发原理探讨的基础上,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,提出了极化波分解、坐标系统旋转等使轨道式可控震源井间地震信号记录与常规井间地震资料保持一致的预处理方法。本方法在胜利垦71井间地震实验区的资料处理中获得了很好的应用效果。

Based on the discussions to the theoretical analysis and blasting principles of the tracked vibroseis together with the real data to conduct the pre-processing of the cross-hole seismic data recorded by tracked vibroseis. Polarization wave decomposition, coordinate system rotation, etc, were proposed in which pre-processing were conducted to make cross-hole seismic signal recorded by the vibroseis consistent with conventional cross-hole seismic data. A good result has been achieved by using this method in the pilot project from KEN 71 area.
