摘　　要：作者在本文中将三维切片视为二维图像 ,利用图像边缘检测技术 ,检测出相干切片上断层多边形 ,并将其直接投影到测网底图上 ,用于构造成图。该项技术不仅提高了用相干切片解释断层的精度 ,而且提高了断层解释效率 ,使相干数据体技术在三维解释中的作用得到更大的发挥。实际应用表明 ,三维相干切片断层多边形检测技术 ,是全三维高精度解释的有力工具 ,提高了解释效率 。In this paper, the 3D coherence slice is considered as a 2D map, the fault polygons are detected in the coherence slice using map edge detecting technique, and then, the fault is used to achieve the structure map. This technique improves the efficiency and accuracy of fault interpretation and make the coherence technique play a important role in 3D data interpretation. The practical application showed that coherence slice fault polygon detecting technique is a very efficient tool for the whole 3D data interpretation and it reduces the cycle of 3D data interpretation.
