摘要:: 【目的】随着四川石化对长庆原油需求量的急剧增长，兰成原油管道现行的掺混长庆原油输送工艺面临严峻挑战，目前兰成原油管道掺混输送极为复杂，单纯改变掺混比例并非解决之道。【方法】系统剖析了兰成原油管道当前掺混输送的现状，深入探讨了制约掺混量进一步提升的关键因素，主要包括油品物性变化、管道结蜡倾向加剧及停输再启动难度增加等。基于大量运行数据与油品配比实验，详细阐述了针对兰成原油管道全年掺混输送的优化策略，重点分析了掺混后油品凝点控制、掺混比例优化、搅拌工艺改进以及清管作业效率提升等方面的具体措施，并提出了优化方案。此外，为了探索在保障安全运行前提下掺混量的最大可提升空间，对加热输送工艺的安全性及停输再启动策略进行了科学论证。【结果】全面评估了掺混增输对管道运行安全的潜在影响，通过年输量的预测与掺混比例精细调控，计算得出长庆原油全年可掺混输送量的最大理论边界为300×104t，为兰成原油管道的实际运行管理提供了重要的数据支持。【结论】研究成果不仅有助于兰成原油管道运行效率与能力的显著提升，还可为今后掺混输送计划的制定提供实践经验与理论依据。（图5，表9，参33）

Abstract:: [Objective] With the rapid growth in demand for Changqing crude oil by PetroChina Sichuan Petrochemical, the existing process of mixing transportation via the Lanzhou–Chengdu crude oil pipeline is facing significant challenges. Moreover, the mixing transportation process in the Lanzhou–Chengdu crude oil pipeline is highly complex, and merely adjusting blending proportions can hardly provide an adequate solution. [Methods] This paper systematically analyzes the current status of mixing transportation along the Lanzhou–Chengdu crude oil pipeline and examines the key factors that restrict further improvements in blending capacity. These factors primarily include variations in the physical properties of oil products, an increased tendency for wax deposition, and greater challenges in restarting the pipeline after shutdown. Drawing on extensive operational data and blending ratio experiments, this paper elaborates on an optimization strategy for year-round mixing transportation of this crude oil pipeline. It focuses on specific measures such as solidification point control for mixed oil products, blending proportion optimization, stirring process improvement, and pigging efficiency enhancement. Furthermore, a detailed optimization solution is proposed. Additionally, this paper explores the potential for maximizing blending capacity while ensuring safe operation, providing a scientific demonstration of the safety of the heated transportation process and the restart strategy after shutdown. [Results] The potential impact of mixing transportation for capacity increase on pipeline operational safety was thoroughly evaluated. By predicting annual throughputs and fine-tuning blending proportions, the maximum theoretical boundary for annual capacities of mixing transportation with Changqing crude oil was calculated to be 300×104 t. The results of this study provide essential data to support the actual operational management of the Lanzhou–Chengdu crude oil pipeline. [Conclusion] The study results not only facilitate significantly improving the operational efficiency and capacity of the Lanzhou–Chengdu crude oil pipeline, but also provide valuable practical experience and a theoretical basis for the development of future mixing transportation plans.
