涪陵页岩气增压开采供电改造可行性探讨

Feasibility Analysis of Power-supply Modification to Improve Shale Gas Pressurization Mining

涪陵页岩气田焦石坝区块于2018年开始实施气田增压开采工作,采取集气站分散增压模式。根据GB50052-2009《供配电系统设计规范》规定的二级负荷宜由两回线路供电要求,对江汉变电站增加备用电源实施供电改造进行了可行性分析。分析认为,改造方案能消除气田生产用电负荷增加导致的江汉变电站无备用电源以及供电能力不足的问题,提高供电可靠性,保障气田生产稳定,具有良好的经济效益。

Gasfield pressurization mining came into operation in Jiaoshiba Block in Fuling Shale Gasfield in 2018,adopting decentralized supercharging mode in gas gathering station.According to power supply requirements specified by GB50052-2009 Design Specifications for Power Supply and Distribution System,this paper conducts a feasibility analysis of adding emergency power supply to Jianghan Transformer Substation to modify power supply.The analysis shows that modification project implementation contributes to solving the problem of no standby power supply and insufficient power supply capacity in Jianghan Transformer Substation caused by increase of electrical load in Fuling Shale Gasfield production,improving power supply reliability and ensuring stable gasfield production and achieving a good economic benefit.
