The stations of Southwest oil & gas field distributed in Sichuan and Chongqing areas. The stabilized power supply in front stations will be an important guarantee to achieve the digital construction goal. The distributing power requirement, environment and the Si-chuan & Chongqing region climate conditions are not the same in different stations. Take one distributing power model is not feasible,and adaptability analysis of the distributing pow-er model in different stations must be done to make sure the distributing power model is rea-sonable. The research results show that it is necessary to choice the different supplying and distributing power mode to achieve different need, and it is feasible to use the solar energy in unattended stations which have no high power load through the comprehensive analysis of en-vironmental conditions and reasonable calculation, and the supporting management system. It can provide a stable power supply for the stations’digital system, and can optimize the project investment.%西南油气田所辖站场分布在川渝地区，前端站场的稳定电源是站场数字化建设目标重要保障。而各站场配电需求、配电环境和川渝地区的气候条件等综合因素都各不相同，不能采取统一的配电方式，必须对配电方式进行适应性分析。针对前端站场不同的配电需求采用不同的供配电方式，辅以配套的管理制度，在部分无动力用电需求的无人值守井站采用太阳能供电是可行的方案，这样既可以为井站数字化系统提供稳定电源，又可以优化项目投资，节省生产运行成本。
