摘要：随着安居区经济社会的快速发展，周边现有气田产量和管网输气能力不能满足安居区对天然气的需求。川中油气矿拟新建输气管道以实现安居区天然气的合理调配，从根本上解决安居区天然气市场的供需矛盾。
为配合该输气管道的建设，对安居区的天然气市场进行了调查研究，通过调查安居区天然气供需现状，预测未来需求量，发现供需缺口，为安居区实施新的供气方案提供基础数据。
本文首先对安居区用气现状进行概括和分析，并对安居区用气需求进行预测。然后分别对安居区周边气源与供气管网进行了调查，根据安居区现有地貌特点采用水力分析模型进行管网的建设。在此基础上提出安居区的最佳供气方案，最后得出相关结论。

ABSTRACT:With the rapid development of economic and social housing area, the periphery of the existing gas production and pipeline gas transmission capacity can not meet the housing area of natural gas demand. A reasonable allocation of Sichuan oil and gas mine plans to build a new gas pipeline for natural gas in Anju District, from the fundamental solution to the contradiction between supply and demand of natural gas market housing area.
For the construction of the gas pipeline, the housing area of natural gas market was investigated, through the supply and demand of natural gas in Anju district investigation, forecast future demand, found that the gap between supply and demand, and provide basic data for the supply of new housing area.
Firstly, Anju district gas status were summarized and analyzed, and the housing area with gas demand forecast. Then the housing to the surrounding gas and gas pipeline were investigated, according to the construction of housing district of the existing landscape features by hydraulic analysis model of network. On the basis of the optimal supply of housing area, finally draws the related conclusion.
Keywords: Natural gas; Demand forecasting; Pipe network plan
