【摘要】：本论文在借鉴国内外已建同类工程建设经验的基础上,结合本项目建设的工程、自然和环境特点,确定管道设计的总体水平,主要包括:输油工艺的比选,管道规格及材质的比选,A联合站、热泵站及C油库的相关流程设计。MG油田投入开发,油田开采初期采用汽车拉运方式输送原油。由于受自然条件制约,采用的汽车拉运方式油气损耗大,安全可靠性差,管理难度较大,且汽车拉运原油费用高,这些因素都造成了原油生产成本的提高,严重影响了油田可持续发展战略。针对这一问题,本文进行了原油外输管道及各站场方案的优化设计。本论文基于MG油田输油管道工程项目背景和相关基础资料,在详细的水力和热力计算的基础上,针对A联合站→B外输首站管段原油含水率高、B外输首站→C油库管道输送净化油输量小,且后期急剧降低,而造成管线及热泵站投资巨大的问题,提出了A→B管道前期输送净化油,后期输送脱去部分水的含水原油的输油工艺方案,B→C管道前期正输、后期采用正反输的输油工艺方案。并分别对A联合站-B外输首站的16种不同的输油方案及B外输首站-C油库站的15种不同的输油方案进行优化,并结合输油工艺方案的技术经济比选,确定了最优方案。另外,为满足管输要求,设计了合理的站场工艺,从而为该管道确定了技术上可行,经济上合理的推荐设计方案。
[Abstract]:Based on the experience of similar projects built at home and abroad, combined with the engineering, natural and environmental characteristics of this project, the overall level of pipeline design is determined in this paper, including: comparison and selection of oil transportation technology, Pipeline specification and material selection A combined station, heat pump station and C oil depot related process design. MG oil field is put into development. Because of the restriction of natural conditions, the oil and gas loss of the vehicle pulling and transporting mode is large, the safety and reliability is poor, the management is difficult, and the oil transportation cost is high. All these factors cause the increase of the crude oil production cost. The sustainable development strategy of oil field is seriously affected. In view of this problem, this paper carries on the optimization design of the crude oil pipeline and each station. This paper is based on the background of the oil pipeline project in MG oil field and related basic data, on the basis of detailed hydraulic and thermal calculation. In view of the high water content of crude oil in the pipeline section of the first station of A and B transportation, the pipeline transportation capacity of C oil depot in the first station of B and B is small, and the transportation quantity of purified oil in C oil depot decreases sharply in the later period, which results in the huge investment problem of pipeline and heat pump station. This paper puts forward the oil transportation technology scheme for A / B pipeline to transport purified oil in the early stage and the water-bearing crude oil for removing some water in the later stage. The oil transportation process scheme of the B / C pipeline is adopted in the early stage, and in the latter stage, the positive and negative transportation is adopted. At the same time, 16 kinds of different oil transportation schemes of A combined station -B outbound first station and 15 different oil transportation schemes of B outgoing first station -C oil depot station were optimized, and combined with the technical and economic comparison of oil transportation technology scheme, the optimal scheme was determined. In addition, in order to meet the requirements of pipeline transportation, a reasonable station and yard process is designed, and a technically feasible and economically reasonable design scheme is determined for the pipeline.
