摘要
油田生产过程中,井场的抽油设备耗能占比较大,针对部分偏远井场电网故障多、稳定性差等问题,提出一种基于储能优化配置的井场新能源利用方法。通过分析井场负荷波动特性与区域资源禀赋,构建了以经济性、可靠性和环保性为目标的多目标储能优化配置模型,并提出风光储容量配比优化策略与分层储能配置方法。研究结果表明:经过储能优化配置的风光储一体化系统,可再生能源消纳率可从40%~60%提升至80%~90%,系统运行成本较传统供能模式降低47%;案例验证显示,储能容量与峰值负荷最优比例为40%~50%,系统能源自给率达65.2%,投资回收期为4.2年,供电可靠性从92.6%提高至99.6%,年碳排放减少82.7 t。研究成果为油田井场能源结构转型提供了技术路径,对实现油田行业绿色低碳发展具有重要实践价值。
In the production process of oilfield,the energy consumption of pumping equipment for well site accounts for large proportion.In order to solve the problems of multi-faults and poor stability of the power grid in some remote well sites,the new energy utilization method of well site based on energy storage optimization configuration for integrated wind and solar energy storage is put forward.By analyzing the characteristics of well site load fluctuations and regional resource advantages,the multi-objective energy storage optimization configuration model with economic,reliability,and environmental goals is constructed,and the wind storage capacity ratio optimization strategy and layered energy storage configuration method are proposed.The research results show that the integrated wind solar energy storage system with optimized energy storage configuration can increase the renewable energy consumption rate from 40%~60%to 80%~90%,and reduce system operating costs by 47%compared to traditional energy supply modes.The case verification shows that the economically optimal ration of energy storage capacity to peak load is 40%~50%,the self-sufficiency rate of system energy reaches 65.2%,and the payback period is 4.2 years.The power supply reliability increased from 92.6%to 99.6%,and the annual carbon emissions are reduced by 82.7 t.The research results provide a technical path for the transformation of energy structure in oilfield well sites and have important practical value for achieving green and low-carbon development in oilfield industry.
