摘要/Abstract

摘要： 为解决大批量进口委内瑞拉稠油到岸后无法利用管道进行常温输送的难题，对油品黏度的快速预测、掺稀油品均一性和稳定性评价以及不同输送工况下安全掺稀比例确定等关键问题开展了研究，建立了一套以室内掺混实验为基础，以模拟计算为辅助手段的稠油常温掺稀输送工艺分析方法。在对16种进口轻质原油基本物性进行统计分析的基础上，开展了委内瑞拉稠油与3种典型进口轻质原油的室内掺混测试实验，建立了不同掺稀比例下混油黏度速查表，利用该表仅需知道20 ℃下稀油黏度，就可快速确定不同掺稀比例及温度下的混油黏度；通过静置实验，对掺稀后混油的稳定性和均一性进行了评价，测试表明掺稀油品经过10 d的静置仍具有很好的均一性。以日东管道为例，对不同季节掺稀输送方案进行了计算对比分析，提出了确定安全掺稀比例的方法。相关研究成果可为稠油常温掺稀输送管道的安全运行提供支持。

Abstract: In order to solve the problem that large quantities of heavy crude oil imported from Venezuela cannot be transported by pipeline at normal temperature after arriving at shore，the transportation technology research was carried out aiming at some key problems such as the quick prediction of diluted heavy crude oil viscosity,the stability and uniformity evaluation of diluted heavy crude oil and the determination of safe blending proportions under different transportation conditions，and a set of analysis method for transporting diluted heavy crude oil at normal temperature based on indoor blending experiments and assisted by simulation calculation was established.Based on the statistical analysis of basic physical properties of 16 kinds of imported light crude oils ,the indoor experiments of blending Venezuela heavy crude oil with three kinds of typical light crude oil oils respectively were carried out,and quick reference tables of viscosity of diluted heavy crude oils with different blend proportions were established by these indoor experiment data. As long as the viscosity of light crude oil at 20 ℃ was known, the viscosity of diluted heavy crude oil at different blending proportions and temperatures can be quickly determined by using these quick reference tables.The stability and uniformity of diluted heavy crude oil were tested by let stand tests.These tests show that the diluted heavy crude oil samples still keep good stability and uniformity after 10 days of standing.Taking Ridong pipeline as an example,the process of transporting diluted Venezuela heavy crude oil was simulated by self⁃developed calculation program, and a kind of method to determine the safe blending proportions and feasible operation plans was proposed.These research results can also support the safety operation of pipeline of transporting diluted heavy crude oil at normal temperature.
