采油是典型高耗能行业,由于采油系统存在重载、轻载、空载、发电运行工况,抽油机系统电源侧、驱动环节以及负荷侧均处于低能效运行状态。因此,针对性研究此类负荷的节能技术,是一种实现油田采油系统节能减排的重要途径。对驱动环节应用最为广泛的调压、节能电机、断续供电节能技术的特点与现状进行了系统研究。首先在深入分析抽油机电机(BPM)系统工况与能耗特点的基础上,对不改变BPM运行周期与冲次的非参数型节能技术,按照不同节能机理与实现方法进行了分类;其次,对应用比较广泛的调压、节能电机、断续供电等节能技术的特点进行了系统分析;最后,围绕节能效果明显且应用范围更广的节能技术,提出了系统能效精细化分析、多种节能技术融合、区域性节能综合改造等建议。

[Abstract]
Oil production is a typical high energy consumption industry. Due to the heavy load, light load, no-load and power generation operation conditions of the system, the power supply, drive link and load of the pumping motor system are in low efficiency operation state. To solve these problems, the energy saving technology of this kind of load is analyzed. It is an important way to realize the energy saving of oilfield production. The characteristics and current situation of widely applied technologies such as voltage regulation, energy saving motor, intermittent power supply etc. are studied systematically. Firstly, based on the in-depth analysis of the operation conditions and energy consumption characteristics of the beam pumping motors (BPMs), the nonparametric energy saving technologies which do not change the operation cycle and stroke times of the BPMs are classified according to different energy saving mechanisms and implementation methods. Secondly, the characteristics of the widely used energy saving technologies, such as voltage regulation, energy saving motor and intermittent power supply, are systematically analyzed. Finally, as for improving the better energy saving effect and widening application field of the energy saving technology, some suggestions like detailed analysis of system energy efficiency, integration of various energy saving technologies, and comprehensive transformation of regional energy saving are put forward.
