机采井能效指标分析与治理方法探讨

Discussion of Energy Efficiency Index Analysis and Governance Method for Machine Production Wells

随着油田开采难度和机采耗能设备应用规模的加大,机采系统耗电量逐年增大,吨液成本不断增加,生产能耗在成本中所占比重越来越大。为了实现节能增效的目的,根据能耗监测结果,对年度能效数据进行统计,并结合能效指标标准,对能效现状进行区块系统分析,查找耗能设备效率低、耗能指标高的主要原因。采取针对性措施进行治理后,累计节电433.5×104k Wh,系统效率提高到17.53%,为今后节能降耗、实施节能技术改造,保证油田生产系统的经济运行提供可靠依据。

With the difficulty of oilfield exploitation and the increase of the application scale of the machine production energy consuming equipment, the electricity consumption of the machine production system increases year by year, tonnage cost goes up substantially and the share of production energy consumption cost in total cost becomes larger and larger. For the purpose of energy saving and efficiency increasing, according to the monitoring results of energy consumption, the annual energy efficiency data is statistically analyzed. Also, combining energy efficiency index standard, block system analysis of energy efficiency status is carried out. The main reasons of low efficiency and high energy consumption of equipment are pointed out. After the implementation of targeted measures for governance, accumulative electricity saving achieves 433.5×104 k Wh and system efficiency is increased by 17.53%. These implemented measures can provide reliable basis for hereafter energy saving and consumption decreasing, implementation of energy saving technology transformation and guarantee the economical operation of oilfield production system.
