摘要: 影响管道安全可靠性的因素众多且具有随机性,因此直接求解极限状态方程比较困难。应用雷灢菲
法,求解过程简便且精度高。基于可靠性理论和B31G—1991标准,综合考虑腐蚀缺陷长度、径向缺陷深度、腐蚀速
率、壁厚、管材屈服强度、管线内压等可靠性影响因素的随机性,应用雷灢菲法建立腐蚀管道可靠性评价模型,编制了
相应的计算程序。计算结果表明,缺陷深度是管道失效的主要影响因素;管道的可靠性指数随缺陷长度、缺陷深度、
径向腐蚀速率的增加而降低,随着管材屈服强度的增加呈线性增加,随内压的增加迅速减小。

Abstract: In order to provide basic data for optimization of the heavy oil conveying pipeline and research of its energy saving technology, the heavy oil viscositytemperature characteristics and the rheological characteristics were done for the experiment research. The heavy oil viscositytemperature equations and rheological equations were fit by Matlab software and the viscositytemperature curve and the rheologicaltemperature curve were drawn by Origin 8.0 software. The analysis results of fitting viscositytemperature curve and its data show that the relative error is smaller between the calculated value of apparent viscosity and the experimental value; the analysis results of the rheological characteristics show that LengJia heavy oil assumes the characteristics of the Newton fluid between 50 ℃ and 80 ℃; Inspection of the 2norm of error vector of the fitting curve indicates that the fit of the fitting curve with the actual situation is good.

Key words: Heavy oil , Viscositytemperature characteristic ,  MATLAB fit ,  Rheological characteristic
