The Pumping Well Diagnostic Technique is a mathematical method based on wave equation to analyse the problem of pumping well. First of all, the load and displacement at the top of each tapered rod string and at the pump plunger are calculated from the measured load and displacement of the polished rod, and the corresponding subsurface dynagraphs are plotted, then the operation conditions of the pumping system are analysed from the surface and subsurface dynagraphs. All the calculations and analyses are...

The Pumping Well Diagnostic Technique is a mathematical method based on wave equation to analyse the problem of pumping well. First of all, the load and displacement at the top of each tapered rod string and at the pump plunger are calculated from the measured load and displacement of the polished rod, and the corresponding subsurface dynagraphs are plotted, then the operation conditions of the pumping system are analysed from the surface and subsurface dynagraphs. All the calculations and analyses are completed by a computer. Besides the basic principle proposed first by S. G. Gibbs et al. and practical application of this diagnostic techique, a new method for calculating viscous damping coefficient from liquid viscosity, the size of tubing and sucker rod, and pumping parameters is also presented in this paper.

抽油井计算机诊断技术是以波动方程为基础,分析抽油井问题的数学方法。首先根据测得的光杆载荷及位移,计算出每级抽油杆柱顶部及抽油泵柱塞上的载荷和位移,并绘出相应的井下示功图,然后,根据地面及井下示功图分析抽油系统的工况。全部计算和分析工作都由计算机完成。本文介绍了诊断技术的基本原理及其应用,并提出了根据液体粘度、抽油杆和油管直径以及抽汲参数计算粘滞阻尼系数的新方法。

On the basis of analysing the problems on driving pumping units, the paper describes the characteristics of extra high-slip motors and the mechanism for the benefits of reduction in power consumption, increase in production and improvement in the running condition of the pumping system when it drives beam-balanced pumping units. Application results in home oilfields in recentyears show that the extra high-slip motors are suitable for beam-balanced pumping units.

本文从分析游梁式抽油机拖动中存在的问题出发,阐述了超高转差率电动机的特性及其拖动游梁式抽油机时获得节电、增液和改善机、杆、泵运行状况的机理。国内油田的使用情况表明,超高转差率电动机是拖动游梁式抽油机的比较理想的设备。

In this paper the computer diagnostic system of the subsurface dynagraphs of sucker rod pumps is developed. It is composed of a digital dynamometer, a data acquisition interface, and a computer system. The subsurface dynagraphs are calculated and plotted according to the measured load and displacement from a polished rod on the ground. Then, the operation conditions of the whole pumping system can be monitored and diagnosed.
