有杆泵抽油井示功图是分析整个抽油系统工作参数的重要依据。对有杆泵抽油井示功图进行预测,将有助于有杆泵抽油。井的正确的设计和抽油参数的合理调整。本文从分析有杆泵抽油系统的实际情况出发,导出了预测有杆泵抽油井示功图的数学表达式。借助于微型计算机系统计算并绘出有杆泵抽油井地面和井下示功图。本文将重点阐述此项预测技术的理论基础,并对此项技术得出的预测结果和实测结果进行了对比。
Sucker rod pump pumping power diagram is an important basis for analysis of the entire pumping system operating parameters. Predictors of sucker-rod pumping wells will help rod pumping. The correct design of the well and the reasonable adjustment of pumping parameters. Based on the analysis of the actual situation of sucker rod pumping system, this paper derives the mathematical expression of predicted sucker rod for sucker rod pump. With the aid of the microcomputer system, the sucker-rod pumping well surface and underground dynamometer are calculated and drawn. This article will focus on the theoretical basis of this prediction technology, and the predicted results of this technology and the measured results were compared.
