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

摘要: 用γ射线透射法对新疆克拉玛依油田输油管道油垢检测进行了实验研究。实验测量装置由13 7Csγ放射源和NaI(Tl)闪烁晶体探测器等组成。克拉玛依油田油垢厚度响应为ln(N0 /N) =0. 0 0 5 4 8d -0. 0 0 4 6, 石蜡厚度响应为ln(N0 /N) =0. 0 0 5 2 2d -0. 0 1 2 6。结果表明 :油垢厚度响应比石蜡厚度响应更灵敏。

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.
