在西德克萨斯的一口油井上进行的现场试验表明,电潜泵上(Electric Submers ible Pump)使用离心式气体分离器,其分离效率比传统的逆流式气体分离器高,可达到90％。离心式气体分离器可以增加电潜泵的运行时间,降低井內液位,增加原油产量。它的一点不足是对液体冲蚀比较敏感。八十年代初,Amoco公司在德克萨斯州拉巴克市西面的拉维兰(Levelland)地区的一口低量注水生产井上使用了一台电潜泵。这是由于受到地面农田灌溉装置的限制,Amoco公司才第一次使用电潜泵来代替杆式泵机组。该电潜泵上使用的是一台标准逆流式气体分离器。这套装置的实际应用结果表明,由于通过电潜泵的液体中含有过多的气体,使之不能正常工作,井內液位不能被泵低。针对这种情况,我们采取了离心式气体分离器,一方面是为了解决这个问题,同时也是为了实测一下离心式气体分离器的工作效率。
Field tests conducted on an oil well in West Texas show that using a centrifugal gas separator on an electric submersible pump (ESP), the separation efficiency is higher than conventional counter-flow gas separators up to 90% . Centrifugal gas separator can increase the running time of ESP, reduce the liquid level in the well and increase the production of crude oil. It’s a little less sensitive to liquid erosion. In the early 1980s, Amoco used an electric submersible pump on a low-volume injection well in the Levelland area west of Labark, Texas. This is because, for the first time, Amoco has been using electric submersible pumps instead of rod pump units because of the restrictions imposed by surface farm irrigation equipment. The ESP uses a standard countercurrent gas separator. The practical application of the device shows that the liquid level in the well can not be lowered by the pump due to the excess gas contained in the liquid passing through the electric submersible pump. In view of this situation, we have taken a centrifugal gas separator, on the one hand to solve this problem, but also to measure the efficiency of centrifugal gas separator.
