摘　　要：LX构造隆起带跨越两块三维地震采集工区,为了得到目标区更清晰的地质构造,需要进行连片处理,而LX构造走向与原两块三维地震采集所设计的坐标系统不正交,且工区二缺少大地坐标信息。为了获得更好的连片处理效果,采用坐标变化技术,重新定义整个连片区域的坐标系统,不仅解决了连片处理中的坐标丢失和不一致问题,也使地质体得到更清晰的显示,获得了很好的处理效果。LX tectonic zone steps across two work area.In order to gain more clearly geological structure of LX,3-D seismic data,Block-jointed processing scheme should be put into practice.The orientation of LX tectonic zone is not orthogonality with primary reference frame,and the geodetic coordinates of the second area are missing.In order to acquire better processing effect,a new reference frame is defined again for all work area.The coordinate convert technique not only resolve the problem of missing of geodetic coordinate and the disaccord between two area,but also reveal the geological structure more clearly.Processing result proved that the method can accomplish block-jointed processing successfully.
