随着物联网技术的发展，目前可以实时高效地采集抽油机井的油压、套压、回压、电参数、功图、油温等主要参数，动液面目前还没有成熟的实时测试手段，仍要人工测试，而产液量能够做到实时计算^[4-9]，这些实时测试的参数为系统效率的实时计算提供了数据支撑。物联网采集平台的构架如文献10和11所述，该物联网系统把单井及边远站库采集的数据采用无线传感网、专网和公网无线技术（融合WSN、Mcwill、WiMAX、WiFi、3G、GPRS、CDMA、卫星等无线传输技术）组成无线异构网络来进行数据传输；其余计量间、中转站、联合站等站库和距站库较近井场的生产数据及视频信号通过有线网络相连来传输，从而实现数据的实时传输^[11]。

和油井的系统效率相关的物联网采集与传输内容主要包括如图1的主要节点，地面电控柜节点主要采集三相电压、三相电流、功率因数，很多电参数采集硬件直接算出了有功功率曲线、无功功率曲线、功率因数曲线。井口节点主要采集流量（产液量）、油压、套压、回压等参数，应用多相流计算可以获得泵排出压力。环空压力可以通过回声仪获得动液面或者应用毛管测压获得环空泵入口的压力数据。可以采用顺序计算法，抽油机井采油系统能耗模型框架如下图1所示。
