计算机绘制等值图的新方法

A NEW METHOD FOR DRAWING ISOPLETH MAP ON COMPUTER

提出了一种用计算机绘制等值图的新方法。该方法用递归算法，快速、准确地搜索非均匀矩形网格上的等值点，并连接成光滑曲线，减少了对折线等值线再进行光滑处理的程序。用该方法编写的计算机程序已经应用于储层参数分析和油藏数值模拟的前处理及后处理中，为地质资料分析及油田开发方案设计提供了可靠的依据。

A new method for drawing isopleth map on computer is established with recursive algorithm. This method can be used to accurately and rapidly search equivalent point in non-uniform grid. and link them to a smooth curve. The smoothing of ploygonal line contour can be avoided. The isopleth map can provide a reliable evidence for analysis of geological data and design of oilfield development plan.
