摘　　要：高效气锚将重力式分离和离心式分离有机地结合在一起,属综合式气体分离装置,它能使含溶解气的油通过气锚时,产生搅拌、转向和速度突然增加等效果,有助于游离气的析出,实现油气的高效分离,从根本上解决了气体对泵的影响。现场35口井使用表明,高效气锚分离效果理想,能有效地提高泵效,平均泵效由原来的25.9%提高到37.2%。Efficient gas anchor, combining gravity separating type and centrifugal separating type, is a synthetical air separation unit. When oil with dissolved gas passes gas anchor, it will be mixed and steered with high velocity, which is useful for free gas separation.Oil and gas are separated efficiently .Effect of gas on pump is eliminated .Site application in 35 wells shows ,efficient gas anchor can enhance pump efficiency .The averaged pump efficicncy is increased from 25.9% to 37.2%.
