摘 要本论文通过对资料进行讨论，分析了气锚油气分离器分气机理和分气效率的影响因素；介绍简单气锚和旋转气锚的计算方法；设计出了新型旋转气锚。该型旋转气锚利用螺旋片对油气混合物产生的离心力进行分离，一般采纳闭式结构，所有流体均需经过旋转气锚，适合在产量高，油气比较低的井中使用。本文对所设计的气锚进行了理论计算和强度校核，该气锚具有结构简单，分离效率高的优点。深化开展井下油气分离器分气效率的讨论和井下油气分离器设计，对提高抽油系统的管理水平、提高抽油井泵效、改进油气分离器的结构设计等方面具有重要意义。关键词：井下油气分离器；气锚；工作机理；分气效率AbstractThe thesis analyzed of the gas anchor oil-gas separator mechanism and the separation efficiency of the gas;It introduced simple gas anchor and rotary gas anchor method of calculation and designed a new type of rotating gas anchor;This type of rotary screw gas anchor unit of the oil and gas mixtures were separated by centrifugal force,generally used the closed structure,after all the required rotary fluid gas anchor;This rotary gas anchor suitabled for the high yield and relatively low oil and gas wells.In this paper, a theoretical calculation of the design of gas anchor and strength check was done.The gas anchor was simple in structure and had high separation efficiency. So an in-depth study of oil-gas separation efficiency of downhole oil-gas separators had important meaning for improving control level of oil pumping system, increasing pumping efficiency of production wells and improving structure design of oil-gas separator.Key words: downhole oil-gas separator; gas anchor; operate principle; gas separator efficiency目 录第 1 章 前 言 11.1 问题的提出和讨论意义.....................................................................1第 2 章 气锚油气分离机理讨论........................................................22.1 分气原理 22.2 常用气锚综合对比 52.3...
