检测输油管道实际油垢样品的实验研究

Experimental Research to Detect Grease Stain in Petroleum Pipeline

在石蜡实验基础上,本工作运用γ射线散射法检测油垢样品进行对比实验研究,并在进一步的实验研究中探讨康普顿散射光子数与油垢样品厚度之间的线性关系.发现放射源与油垢样品之间的距离与提高线性度有很大关系.本实验测得最佳线性相关系数平方值为0.9871,测量精度为0.671mm.

Based on the experimental research on paraffin,γ-ray scattering method was used to detect grease stain sample in petroleum pipeline in comparison. The linear relationship between the Compton Scattering count number and the thickness of the grease stain sample was explored in further experimental research. It is found that the distance between radiator and grease stain sample made important role in improving the linear degree. The best value of the experimental measuring square coefficient of the linear correlation is 0.9871 and the value of the measuring accuracy is 0.671 mm.
