摘要
现有井下油气分离器效率较低,已不能满足高油气比油井的生产需要,为了解决高含气井中井下多相混抽泵或电潜泵的使用与效率低等问题,开展了井下离心旋流式高效油气分离器的研究。该分离器采用2级串联结构,以水力旋流器为第1级;以对结构进行了优化改造的离心旋转式分离器为第2级。通过试制样机的室内模拟试验,验证了新设计的井下离心旋流式高效油气分离器的分离效率,总分离效率可达95%以上,其对含气体积分数的适应范围由原分离器的0～36%提高到0～50%,能够满足较高含气井井下油气分离的要求。
In view of current oil-gas separator's disadvantages,high efficiency cyclone centrifugal oil-gas separator is developed for the multiphase pump or the electrical submersible pump in high GOR wells.The new oil-gas separator is a two-stage tandem separator,which is composed of hydrocyclone and centrifugal revolving separator that has been optimized.Hydrocyclone is the first stage,and the optimized revolving separator is the second one.The prototype test verifies the separation efficiency of the new separator,and the test data show that the separation efficiency of the new separator can satisfy the requirement of downhole oil-gas separation in the higher GOR wells.
