Abstract

The current conditions of well operation with electric submersible pumps are characterized by the need for gas separation at the pump intake, and natural separation can be insufficient to provide the technological rate of well, so gas separators are used as part of the electric submersible pump unit. The literature review and the results of our research demonstrate that currently there is no unified methodology for selecting gas separators of various designs for the operating well conditions, equipped with ESP units of different series. That is, the selection of a gas separator as part of ESP unit is based on partial data on performance and design of the gas separator, which is unacceptable, and in some cases dangerous due to the possible failure mode. The paper describes a methodology to predict the efficiency of a gas separator as part of a downhole electric submersible pump unit based on the summary of a significant set of statistical information from publications, results of our own experimental and field studies. Keywords: gas separator; gas content; electric submersible pump unit; ESP; separation efficiency; well oil production; separation coefficient.

确定作为电动潜水泵装置一部分的气体分离器效率的方法

目前使用电潜泵的油井运行条件的特点是需要在泵的进气口进行气体分离，而自然分离可能不足以提供油井的技术速率，因此气体分离器被用作电潜泵装置的一部分。文献综述和我们的研究结果表明，目前还没有统一的方法来选择配备不同系列静电除尘器装置的各种设计的气体分离器，以适应油井的运行条件。也就是说，选择气体分离器作为静电除尘器装置的一部分是基于气体分离器性能和设计的部分数据，这是不可接受的，在某些情况下，由于可能的失效模式，这种选择是危险的。本文介绍了一种预测作为井下电潜泵装置一部分的气体分离器效率的方法，该方法基于对出版物、我们自己的实验和现场研究结果中的大量统计信息的总结。关键词：气体分离器；气体含量；电潜泵装置；ESP；分离效率；油井采油；分离系数。
