| 摘 要： | 针对普通三角剖分算法构造三角网经常出现尖锐三角形的问题,提出了一种河流相储层河道砂体沉积相带自动追踪算法.该方法通过插入伪井进行优化Delauny三角剖分设计,结合单向、双向链表及井距比例因子,较好地解决了以往沉积相带图河道砂体跨井排不连续和宽窄不一的问题,在QX油田实际应用中取得了较好的效果.

| Abstract: | An algorithm is put forward which can be used to trace the boundary of the channel sandbody in fluvial facies reservoir. It optimizes Delauny's triangulation by interplating pseude-wells. Together with the design of one-way and dual link list and the restriction of well-spacing proportion factor, the algorithm settles the problems of the discontinuity of the channel sandbody across well rows and the non-uniformity of well-spacings along the river tend in formerly mapping fluvial facies to a certain extent. This algorithm is applied to QX oilfield and a good result is obtained. |
