为改进应用γ射线散射法在原油输运过程中的结垢厚度检测方法,建立一系列模拟实验来研究原油对检测油垢厚度的影响,实验中以石蜡模拟原油。结果表明,在原油厚度小于输油管道内径的三分之一时,随着油垢厚度的改变,散射光子数变化明显,灵敏度较高。在此情况下,用γ射线散射法测量油垢厚度是一可行途径。 In order to improve the detection method of fouling thickness during the transportation of crude oil by using γ-ray scattering method, a series of simulation experiments were established to study the influence of crude oil on the thickness of grease stain. In the experiment, paraffin wax was used to simulate crude oil. The results show that when the thickness of crude oil is less than one third of the inner diameter of oil pipeline, the number of scattered photons changes obviously and the sensitivity is high with the change of grease thickness. In this case, it is a feasible way to measure grease thickness by γ-ray scattering method.
