中文摘要:

      注气三采中制氮注氮系统是一个复杂的系统工程，影响注气系统高效运行的因素较多，如注气压力、单位注气量、环境温度、湿度等，且当前尚缺乏制氮注氮系统能耗分析与评价手段。结合塔河油田的现状和工艺流程，利用能量分析和㶲分析方法，对注氮系统各设备和系统进行能耗分析，结果表明TK680能源有效利用率和㶲效率分别为14.04%和18.07%，找出用能薄弱环节为PSA和空压机。同时针对用能的薄弱环节提出改进措施：加装余气回收及热能回收装置、空压机采用变频调节或集中控制技术。

英文摘要:

      The nitrogen in jection system is a complicated system. Many factors influence the efficiency of the system, such as injection prssure, injection volume,ambient temperature and humidity etc. There is few energy analysis and assessment of nitrogen injection system, Base on the technological process of the Tahe oil field, theenergy consumption of each equipment and the system is analyzied by suing energy analysis and exergy analysis. The results show that the energy transmission efficiency and exergy efficiency of TK680 are 14.04% and 18.07% respectively. The weak parts of energy utilization are PSA and air compressor. Measures for improving the weak links are put forward: adding residual gas recovery and heat recovery equipments, and adopting variable frequency regulation or centralized control technology for air conpressors.
