针对聚合物驱采油井在受效后生产过程中其受效初期、中期、后期三个阶段受效持续时间不同,产量和设各参数变化幅度较大等特点,重点对聚驱并受效动态分析图的作用、框架设计的基本技术思想、区域确定原则、计算机绘图方法及作图原理等四个方面作了详尽的介绍,该图以聚驱受效前数据和聚驱某阶段数据为基础数据库运行对比分析,经计算机处理自动生成图型,为生产分析和决策等提供依据。

In view of the different effectful lasting time and the great change of output and equipment parameters during the initial, middle and last effectful stages of the oil producing wells with polymer flooding, this paper introduces in detail the action of the effectful performance analysis chart of the oil producing wells with polymer flooding, the basic technical thought of the frame design, the principles for region determination, as well as the mapping method and principle of computers. This chart contrasts and analyzes the relevant data before and after the polymer taking effect, produces plot automatically through computer processing, and provides basis for production analysis and decision.
