    Abstract
  • In view of the difficulties of paraffin removing in acidic condensate gas wells in the 9th district of the Tahe Oilfield, we analyzed the composition and physical/chemical property of sedimentary clogs by means of X-ray diffraction, energy spectrum, infrared spectrum and DSC tests. Different from paraffin deposited in conventional condensate gas wells, the clogs in the 9th district were mainly microcrystalline wax, with melting temperature above 82 ℃. According to wax features and field work situations, a paraffin removal technique with oil soluble chemical paraffin removal agent and paraffin inhibitor through slim tube was recommended for the study area.
