Abstract

Abstract A common problem verified in the sucker rod pumping technique is fluid slippage, reducing pump efficiency (PE). Approaches relating to the influence of water cut, viscosity, and clearance on fluid slippage lacks discussions in the literature. Thus, this work aims to study the effect of these three parameters upon slippage and PE. Rheological analyses were carried out to determine emulsions viscosities. The obtained data were inputs parameters in the QRod—Echometer software. The results showed that clearance was the parameter that most influenced the pump efficiency, and for fluids with low viscosity, the PE will be optimized when clearance is reduced.

有杆抽油井含水和间隙对泵效率的影响分析

摘要有杆抽油技术中一个常见的问题是流体滑移，降低了泵的效率。关于含水率、粘度和间隙对流体滑移的影响的方法在文献中缺乏讨论。因此，本工作旨在研究这三个参数对滑移和PE的影响。进行流变学分析以确定乳液的粘度。所获得的数据是QRod——Echometer软件中的输入参数。结果表明，间隙是影响泵效率最大的参数，对于低粘度流体，当间隙减小时，PE将得到优化。
