【摘要】：随着我国清洁能源战略的实施,对清洁、高效、环保的天然气资源需求量也越来越高,近年来铺设了大量长距离输气管道以满足国内的能源需求。输气管道项目中输气站场是整个管道系统的核心,不仅为输送的天然气提供动力,还要维护整个系统的安全、高效运行。长输管道输气站场具有设备多、危险性高、技术复杂等特点,需要采用科学方法维护系统的安全,保障站场功能。本文首先对国内外输气管道项目的发展现状进行了调研,特别调研了天然气站场的风险评价、安全管理方法和管理现状。再对贵阳输气站的周边环境、主要工艺流程、核心设备和安全管理制度等进行细致调查和研究,建立了基于贵阳输气站实际情况的安全检查表。安全检查表将贵阳输气站总系统分为管道、设备、运行、管理、事故处置和环境等六个分系统,对每个分系统提出若干安全检查问题,涵盖了贵阳输气站的主要风险问题。使用针对贵阳输气站编制的安全检查表,通过现场检查、问询现场工作人员、查阅管线和站场资料的方式对贵阳输气站和管辖管线进行了定性风险评价。评价结果表明贵阳输气站的主要分系统92%以上的检查项目满足安全管理要求,整体风险管理水平较高,但也存在少量管线标志不清,消防设备不齐全等情况,并给出了具体的整改意见。根据贵阳输气站的安全评价结果和安全管理规定,建立了贵阳输气站应急管理体系。首先介绍了应急管理体系的概念、原则和应急预案等内容。分析了贵阳输气站的综合应急预案、专项应急预案和现场应急预案等三类应急预案体系。结合输气站场的主要风险类型,建立了调控应急处置、燃气泄露、火灾爆炸和站场突然停电等专项应急预案措施,提高了现场应对紧急情况的能力。
[Abstract]:With the implementation of the clean energy strategy in China, the demand for clean, efficient and environmentally friendly natural gas resources is increasing. In recent years, a large number of long-distance gas pipelines have been laid to meet the domestic energy needs. The gas transmission station is the core of the whole pipeline system, which not only provides the power for the natural gas transportation, but also maintains the safety and efficient operation of the whole system. The gas transmission station of long distance pipeline has the characteristics of many equipments, high risk and complicated technology, so it is necessary to adopt scientific methods to maintain the safety of the system and ensure the function of the station yard. In this paper, the development status of gas pipeline projects at home and abroad has been investigated, especially the risk assessment, safety management methods and management status of natural gas stations. The surrounding environment, main technological process, core equipment and safety management system of Guiyang gas transmission station are investigated and studied carefully, and a safety inspection table based on the actual situation of Guiyang gas transmission station is established. The total system of Guiyang gas transmission station is divided into six subsystems: pipeline, equipment, operation, management, accident disposal and environment. Several safety inspection problems are put forward for each subsystem, which covers the main risk problems of Guiyang gas transmission station. Based on the safety check list for Guiyang gas transmission station, the qualitative risk assessment of Guiyang gas transmission station and the competent pipeline is carried out by means of on-site inspection, interview with field staff, and reference of pipeline and yard data. The evaluation results show that more than 92% of the main sub-systems of Guiyang Gas Transmission Station meet the requirements of safety management, and the overall risk management level is relatively high. However, there are still a small number of pipeline signs unclear and fire fighting equipment not complete, etc. And gives the concrete rectification opinion. According to the safety evaluation results and safety management regulations of Guiyang gas transmission station, the emergency management system of Guiyang gas transmission station is established. Firstly, the concept, principle and emergency plan of emergency management system are introduced. The comprehensive emergency plan, special emergency plan and field emergency plan of Guiyang gas transmission station are analyzed. Combined with the main risk types of gas transmission station, the special emergency plan measures, such as regulating and controlling emergency disposal, gas leakage, fire explosion and sudden power outage in the station yard, were established, which improved the ability of dealing with emergency situations on the spot.
