建立了油田注汽锅炉本体及机组系统的热力学分析模型，给出了其评价分析准则。并根据测试数据对ＳＦ—２０型热注机组进行了能■平衡计算，同时依据计算结果制定了提高该机组运行热效率的技术方案。
The thermodynamic analysis model of steam injection boiler body and unit system is established, and its evaluation criteria are given. Based on the test data, the SF-20 hot-steam injection unit can be used for the balance calculation. At the same time, the technical scheme for improving the thermal efficiency of the unit is developed based on the calculation results.
