- 摘要:
- 中国油气体制改革进程中，石油公司下辖天然气管道与国家管网集团、省级管网公司下辖管道互联互通构成大型天然气管网，其具有气源/资源类型多样、不同管段设计/运行压力不同、下游用户类型复杂、用气规律多样等特点。为研究该类管网运行供需平衡问题，借助SPS软件对双气源、多用户管网进行仿真建模，在对现有管网运行参数进行可靠性验证的基础上，结合用户2025年用气需求对管网供需平衡问题进行仿真分析，并提出优化运行方案。结果表明：通过分输站对两路气源进行压力平衡的优化方案不仅能够满足下游用户双气源保供需求，同时资源分配更加平衡，尤其在冬季保供期，极大地分担了国家管网冬季保供压力，提升管网整体保供能力，可为管网现场运营调度提供指导。（图6，表5，参24）
- Abstract:
- In the process of oil and gas system reform in China, it is found that there are some problems in the large-scale natural gas pipeline network that is composed of natural gas pipelines under the jurisdiction of oil companies, pipelines under the jurisdiction of PipeChina, and pipelines under provincial pipeline network companies. For example, the types of gas sources/resources are diverse, the design/operating pressures of different pipelines are different, the types of downstream users are complicated, and the gas consumption rules are diverse. In order to study the supply-demand balance of such pipeline network in operation, the pipeline network with dual gas sources and multi-user was modeled using SPS software. Based on the reliability verification of the operation parameters of existing pipeline networks, considering the gas demand of users in 2025, the supply-demand balance of the pipeline network was simulated and analyzed. Then, an optimized operation scheme was proposed. The results show that the optimized scheme of pressure balance of two gas sources through the off-take station can not only meet the demand of dual gas sources for downstream users, but also make the resource allocation more balanced. Especially, in the winter supply period, the scheme can greatly share the pressure of PipeChina in winter and improve the overall supply capacity of the pipeline network, and thus it could provide guidance for the on-site operation and dispatching of the pipeline network.
