| 摘 要： | 为了减少气体对泵的影响,提高抽油泵泵效,研制了井下复合式气液分离器。该气液分离器将重力分离和旋流分离有机地结合在一起,能使含溶解气的油流产生搅拌、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,可大大减少气体对泵的影响。现场应用表明,复合式气液分离器可使油流中的自由气在进泵前分离出来,通过油套环形空间排到地面,减少气体对抽油泵的影响,特别对高含气井有较好的气液分离效果。 |

| Abstract: | In order to reduce the influence of gas on pumps and improve the pumping efficiency, a combined downhole gas-liquid separator is developed. In the separator, gravity separation is combined with cyclone separation, by which blending, steering and immediate increase of velocity would induce in the oil stream containing dissolved gas, help extract the free gas and realize high efficient separation of oil and gas to greatly reduce the influence of gas on pumps. Field application indicates that the combined gas-liquid separator can be used to separate the free gas in oil stream before it comes into the pumps, and discharges it to surface through the annular space between tubing and casing, thus to reduce the influence of gas on oil pumps, better result of gas-liquid separation would be obtained especially for high gas content wells. |
