摘　　要：介绍了抽油机井系统效率的数学模型及系统效率控制图的功能 ,论述了抽油机井系统效率控制图绘制系统的设计方法 .绘制系统可实现抽油机井系统效率控制图的显示和打印 ,并能依据打印纸在当前打印机上的行列点阵数 ,对图形放大处理 ,实现了图形的打印可随打印纸的大小而变化 。System efficiency control graphics of pumping unit well is an important reference to management and decision-making of oil well producing. This paper introduces mathematical model and function of system efficiency of pumping unit well, discusses the design method of drawing the graphics. The system is capable of printing and displaying the graphics. In printing the graphics, we enlarge the graphics according to the dot number of printpage's height and width, so that the size of the graphics will change with the size of the printpage and not depend on printers.
