【摘要】：随着我国天然气消耗量的急剧增加,天然气进口已成为缓解我国能源压力的重要手段。在我国天然气进口管线中,ZM天然气输送管道已出现了较为严重的输差问题,超出了可接受范围,不仅给交接双方经济带来了较大影响,还影响着双方的国际贸易合作关系。因此对该管线展开输差产生原因分析,确定问题属性,确保天然气输量的准确、可靠和统一,对改进生产工艺、提高产品质量、降低产品成本、提高经济效益及社会效益有着积极作用,有利于维护双边国际贸易合作关系。故本文针对ZM天然气管道的输差问题开展了以下几个方面的研究:首先,收集和整理国内外天然气长输管道和燃气管网的输差分析控制基础理论,分析比较了数据挖掘技术在国内外的发展现状和研究成果。从天然气长输管道输差构成的角度分析了输差产生的原因。结合ZM天然气管道现场运行情况和数据,认为引起ZM天然气管道输差增大的因素可能是管存计算偏差、放空量和自用气量。其次,从压缩因子的计算、管段细分程度两方面对管存计算进行研究和优化,得到适合ZM天然气管道的管存计算方法。在压缩因子计算方面,通过对比8种常用状态方程和8种经验公式,优选AGA8-92DC计算方法,在计算时间和求解过程两方面优化AGA8-92DC计算方法。在管段细分程度方面,结合ZM天然气管道实际分析,制定最优管段划分方案。然后,运用灰色关联度分析法,对ZM天然气管道输差相关的历史数据和记录进行分析,确定影响输差的主要因素。利用数据挖掘技术中的关联规则方法,进一步挖掘历史数据和记录,得到影响因素和影响规律。最后,运用C#语言编制了 ZM天然气管道输差分析程序,采用编制的程序对ZM天然气管道2015年～2016年上半年输差相关数据以及记录进行了实例计算和分析,分析结果表明,该程序有较高的可靠性和实用价值。
[Abstract]:With the rapid increase of natural gas consumption in China, the import of natural gas has become an important means to alleviate the energy pressure of our country. In the natural gas import pipeline of China, the ZM natural gas pipeline has appeared more serious transmission difference problem, which is beyond acceptable range, not only has brought great influence on the economy of the two sides, but also affects both sides. Therefore, the analysis of the causes of the pipeline expansion, the determination of the problem attributes, and the accuracy, reliability and unity of the natural gas transmission, have a positive effect on improving the production process, improving the quality of the product, reducing the cost of the product, improving the economic and social benefits, and is conducive to the maintenance of bilateral international trade cooperation. Therefore, this paper studies the following aspects of the ZM gas pipeline transmission problem: first, to collect and collate the basic theory of the transmission analysis and control of natural gas pipeline and gas pipeline at home and abroad, analyze and compare the development status and research results of data mining technology at home and abroad. The cause of the transmission difference is analyzed in the angle of formation. Combined with the field operation and data of ZM natural gas pipeline, it is considered that the factors that cause the increase of ZM gas pipeline transport difference may be the calculation deviation, the free volume and the self use gas quantity of the pipe storage. Secondly, the calculation and optimization of the tube storage calculation from the calculation of the compression factor and the subdivision of the pipe section two are studied and optimized. It is suitable for the calculation method of pipe storage for ZM natural gas pipeline. In the calculation of compression factor, by comparing 8 common state equations and 8 empirical formulas, optimizing the AGA8-92DC calculation method, optimizing the AGA8-92DC calculation method in the calculation time and solving process two aspects. In the aspect of subdivision of the pipe section, combining with the actual analysis of the ZM natural gas pipeline, the optimal method is formulated. Then, using the gray correlation analysis method, the historical data and records related to the ZM gas pipeline transport difference are analyzed, and the main factors that affect the transmission difference are determined. Using the association rules method in the data mining technology, the historical data and records are further excavated and the influence factors and influence laws are obtained. Finally, the use of C# language is used. The ZM gas pipeline transmission analysis program is compiled, and the program is used to calculate and analyze the data and records of the ZM natural gas pipeline from 2015 to the first half of 2016, and the results show that the program has high reliability and practical value.
