Produced fluid profile testing tech for swabbing deeply in oil well and passing pump
Keywords:
Deep swabbing and passing pump, Finding waterAbstract
To find producing water section accurately in oil well, produced fluid profile testing tech for deep swabbing in oil well and passing pump has been studied. An empty testing swabbing pump is hung in case inner 2000 meters depth during checking pump operation and swabbing deeply to produce fluid is completed by tube to drive. Testing instrument is lowered to reach objected section through post of pump and test is made without stopping pump to acquire produced fluid profile data to judge main producing water layer so as to conduct a pertinence blocking water operation. This tech suits for oil wells of inclined, dense oil, screw pump, electrical submersible pump and hydraulic power pump in which annulus testing can not be conducted. Over 50 wells applied in Huabei oilfield, an exact data is provided for judging exploiting plan of oilfield.
