GDI+在复杂地区三维地震资料采集设计中的应用

APPLICATION OF GDI+ IN THE 3D SEISMIC DATA ACQUISITION IN COMPLEX AREAS

随着油气勘探向复杂地区延伸,三维地震资料采集难度日益突出。在复杂地区许多激发点位于多个禁炮区内,依靠手工很难完成激发点的正确筛选。这里采用基于GDI+生成禁炮区,可以自动选择所有非禁炮区内的激发点。实际应用表明:方法具有建立速度快、运行稳定可靠等特点,并取得了好的应用效果。

With the extension of oil and gas exploration to complex areas,the difficulty of the 3D seismic data acquisition is becoming increasingly.It is impossible to choose shot points exactly by hand because many shot points lie in forbidden shooting regions in complex areas.The paper offers a method based on GDI plus to create and store the forbidden shooting regions which results in auto-choosing shot points correctly.The practical application shows that the method works reliably in high speed and satisfactory results have been achieved.
