摘　　要：川渝地区水电及天然气资源的产输规模均位居全国前列,但两种能源在该区的互补利用效率并不高。为了提高能源综合利用效率,结合川渝地区的实际情况,探索性地提出了天然气和水电资源“气水融合”的发展战略:基于四川水电存在“丰多枯少”及川电外输线路季节性闲置、川渝两地天然气面临上游快速增储上产而下游消费市场增速放缓,且管道外输受限局面的特点,充分发挥川渝地区储气库群的季节调峰作用,探索采取在夏季丰水期储气用电,冬季枯水期采气发电外输的模式,实现气水互补融合发展。研究结果表明:①川渝地区实施气水融合发展战略具有发电用气潜力大、储气库加速布局建设、气电技术发展成熟、气源资源地综合成本低、发电企业积极参与气电项目等基础条件和资源优势,能够提高地区清洁电力供应质量,实现相关企业提质增效发展的内在需求;②制约气水融合发展的问题主要为体现气电环保调峰价值的上网电价机制未建立、气电燃机设备采购及运维费用偏高、供气价格影响气电的经济效益等。最后,针对性地提出以下优化途径与建议:①构建气水融合战略合作联盟以优化内部协调配置;②合力争取气水融合发展的相关规划及配套政策;③在川渝地区加快推行气电上网两部制电价;④跟进并出台国产燃机示范项目的配套扶持政策;⑤建立储气电价与发电气价的价价优惠联动机制等。The production capacity and export scale of hydropower and natural gas resources in the Sichuan-Chongqing area are among the top in China,but their complementary utilization efficiency in this area is not high.In order to improve the comprehensive energy utilization,this paper puts forward an exploratory proposal on the integrated development strategy of natural gas and hydropower resources based on the actual situations in the Sichuan-Chongqing area.In view of that the hydropower in Sichuan has long high-water period and short low-water period,the Sichuan power export lines are idle seasonally,and the natural gas in the Sichuan-Chongqing area faces the contradiction between the rapid reserve and production increase in the upstream and the slow consumption market growth in the downstream,as well as restricted pipeline transportation,a mode of electric power was explored for gas storage in the high-water period of summer and gas production for power generation and export in the low-water period of winter by giving a full play to the seasonal peaking shaving effect of the gas storages in the Sichuan-Chongqing area,so as to realize the complementary and integrated development of natural gas and hydropower.And the following research results were obtained.First,the integrated development strategy of natural gas and hydropower in the Sichuan-Chongqing area has basic conditions and resource advantages,such as great potential of natural gas for power generation,high-speed layout and construction of gas storages,development and maturity of gas-fired power technologies,low overall cost at gas source locations,and active participation of power enterprises in gas-fired power projects,which can improve the local supply quality of clean power and meet the internal demand of related enterprises for quality and efficiency improvement.Second,the problems that hinder the integrated development of natural gas and hydropower mainly include unavailable on-grid electricity pricing mechanism embodying the environmental protection and p
