Abstract: Large scale application of wireless sensor net for industry field monitoring and control is inadequate based on the analysis of oil－gas exploiting process，The feasible well－site monitoring system solution，which adopt suitable techniques
were proposed．The solution includes：wireless instrument interface card，star and Mesh topology，hybrid power supply of main and battery，power management based on application requirement．The simulation result of dynamic power management indicates that large percentage battery power can be saved under steady operation conditions．

Key words: Oil－gas exploiting , Well－site monitoring , WSN , Power management

摘要： 基于油气开采过程监控需求的分析研究，提出了基于无线传感器网络的油气开采监控系统可行方案。该方案包括：现有井场仪表与无线接口卡结合，星型加 Mesh型的拓扑结构，电源供电为主、电池供电为辅的供电方式，基于监控需求的动态能量管理。动态能量管理方法的仿真结果表明，监控系统在设备稳定运行的条件下能够节约大部分的电池能量。
