油田加热炉节能运行的综合评价系统开发

基于Visual Basic语言和Access数据库管理工具开发了油田加热炉综合评价系统软件,在实现油田加热炉工艺参数计算的基础上,运用基于熵权的灰色关联分析理论对加热炉的节能运行进行综合评价。对某油田加热炉的应用实例分析结果表明:不同评价指标对加热炉运行的影响程度不同,其重要程度排序依次为:排烟温度、炉体外表面温度、空气系数、热效率;按照关联度数值大小可判别各台加热炉运行情况的优劣,其值越接近1,加热炉运行效果越优,否则为用能薄弱设备。由此为提高油田总体用能水平提供了更具操作性的依据。

Development of a comprehensive evaluation system for energy-saving operation of oilfield heaters

Comprehensive evaluation system software of heater for oilfield use is developed based on Visual Basic Language and Access database management tool.This system can be used to assess the energy saving rate of the heater according to the gray correlation analysis theory of entropy weight by calculated process parameters of heaters.Case analysis indicates that different evaluation indicators have different influences on the energy saving rate of heater,and the priority sequence of which lists as follows,exhaust temperature,outside surface temperature of heater,air coefficient and thermal efficiency.The energy saving rate of each heater can be confirmed in accordance with the magnitude of correlativity.If the value is closer to 1,the heater runs better,otherwise it is considered as weak equipment.Thus a more operational basis is provided for the oilfield to improve its overall energy consumption level.
