Preliminary Experimental Research to Detect Grease Stain of Petroleum Pipeline by ~(137)Cs γ-ray Transmission Method

    Graphical Abstract
    • Abstract
  • The experimental study on the detection of grease stain for petroleum pipeline in Karamay oil-field of Xinjiang is carried out by γ-ray transmission method. Experimental provision consists of 137 Cs γ radiator and NaI(Tl) scintillation detector. The response of grease stain thickness of petroleum pipeline in Karamay oil-field is ln( N _0/ N )=0.005 48 d - 0.004 6, and the response of paraffin thickness is ln( N _0/ N )=0.005 22 d -0.012 6. The result of experiment indicates that the response of grease stain thickness is more sensitive than the response of paraffin thickness.
