多组分混合原油凝点与粘度的图示方法

Pour Point and Viscosity Charts for Multi-Constituent Mixed Crude

在多组分混合原油凝点和粘度计算公式的基础上，利用正三角坐标法，比一般图表法更加直观而精确地确定其的凝点和粘度。同时，根据工程需要想得到更精确的值，只要设定更小的等值坐标系步长，就可以满足所需。利用正三角坐标法也以可确定一定凝点或粘度后配比混合原油组合。

On the basis of pour point and viscosity counting formulas of multi-constituent mixed crude and in order to determine the pour point and viscosity of the crude,it is more direct and accurate by using the regular triangle coordinate method than by using ordinary charts. Moreover, you can meet the need of necesssary accuracy by setting smaller length of equal value coordinate system. After the pour point or viscosity de fihed,the compounding ratio of constituents of mixed crude also can be determined' by using the regular triangle coordinate method.
