摘要：随着经济社会发展，遂宁市天然气需求迅猛增长。根据调研资料测算，到2022年遂宁市天然气需求达280.8亿方/年，比2012年增长4.7倍，年均增幅19%，遂宁市现有天然气产量和输配能力已不能满足未来用气需要。针对这个问题,进行了天然气保规划。以磨溪气田雷一1气藏和磨溪气田嘉二气藏为主要气源，以北内环和北干线为第二气源，形成“主要气源为主、第二气源为辅”双重保障，从而从气源上保证天然气的供应；对输气能力不能满足未来需求的区域，根据大宗用户用气进度建设8条输气管道及配套设施，保障天然气的输送。除此之外，还对遂宁市未来20年天然气的需求变化进行了预测评估，证明了此保障规划是可行的。

ABSTRACT:With the economic and social development, rapid growth in demand for natural gas Suining City. According to research data estimates, the demand for natural gas in 2022 Suining 28.8 billion cubic meters / year increase of 4.7 times over 2012, an annual increase of 19%, Suining City, the existing natural gas production and transmission and distribution capacity can not meet future gas needs. For this problem, a gas protection case. To mine a one Moxi Moxi Gas Field gas reservoir and gas pool Kerry two main gas source, north of the inner ring and the Northern Route is the second gas source, a "main gas source-based, supplemented by a second gas source." double protection to ensure that natural gas from the gas supply source; pair transmission capacity can not meet the future needs of the region, according to the progress of construction of large users 8 gas pipelines and ancillary facilities, thus ensuring the delivery of natural gas. In addition, also for the next 20 years, Suining City, changes in demand for natural gas evaluation and financial evaluation of the prediction proved this construction is feasible.
