摘要: 随着深海及边际油田的不断开发,FPSO(浮式生产储卸油装置)广泛应用于海上油气田开发。FPSO作为兼具产能和耗能的油气生产装置,在满足其用能需求的前提下,采取一个经济的能源分配方案,不仅有利于降低建设成本,同时有助于提高整个系统的能源利用率,促进节能。以能源系统年总成本费用最低为目标函数,在考虑能源平衡约束和技术约束的条件下,建立并求解一个FPSO分布式能源系统的混合整数线性规划(MILP)模型,以此确定年总成本最少的情况下的设备选择和容量以及相应的运行方案,从而达到节能降耗的目的。以渤海某FPSO为实例,对模型进行了计算验证。结果表明,与传统的运行方案相比,分布式能源系统可降低经济费用14.6%。此外,研究了能源价格对系统经济性的影响,发现天然气价格的上涨对DES(分布式能源系统)设计和运行影响较大。

Abstract: With the developments of deep sea and marginal oil fields, FPSO has been widely used in offshore oil and gas field development.FPSO, as an oil and gas production device with both energy production and consumption, takes an economic energy distribution scheme on the premise of meeting its energy demand, which not only helps to reduce construction costs, but also helps to improve the energy efficiency of the entire system and promote energy conservation. Taking the annual total cost of energy system as the objective function, the MILP model of FPSO distributed energy system is established and solved under the conditions of energy balance and technical constraints to determine the equipment selection and capacity, and the corresponding operation plan to achieve the purpose of energy conservation and consumption reduction. The model is validated by an example of FPSO in the Bohai sea. The results show that the cost of distributed energy system can be reduced by 14.6% compared to traditional operating schemes. In addition, considering the impact of different energy prices on the economy of the system, it is found that the increase in natural gas prices has a great impact on the design and operation of DES.
