针对在沉积相带追踪中，常规三角剖分算法构造的三角网无法自动解决河道砂体跨井排不连通问题，提出了一种相带边界线自动识别方法。该方法的关键步骤是采用逐点插入法先生成无约束三角网；再根据河道砂体连通情况插入虚拟井，并通过该虚拟井建立跨井排井的连通线，将这两条线作为约束边插入第一步生成的三角网中，将三角网部分重构，形成最终约束三角网，对该三角网进行相带边界追踪。系统前端采用。 NET网页框架和Applet网页嵌入技术，核心绘图功能采用Java 2D绘图技术，效果良好。

In sedimentary facies tracing,the triangular irregular network constructed by the conventional triangulation algorithm cannot au-tomatically solve the problem of unconnected the channel sand on different well array,put forward an automatic identification method of the sedimentary facies border curve. First of all,the method adopts the incremental inserting algorithm to generate unconstrained triangular irregular network. Secondly,insert virtual wells according to the channel sand body connectivity,and establish connected line of wells which are on the different well array through the virtual well,then insert the two lines as constraint boundary to the constrained triangular irregular network that generated in the first step,reconstructing a part of the triangular network,forming the final constraint triangulation, and tracing the triangular network facies boundary. Front-end systems uses . NET framework and Applet Web pages embedded technolo-gy,the core graphics function uses Java 2D graphics technology. The result of actual application is good.
