The exploitation of heavy oil thermal recovery methods to inject steam , heavy oil accounted for more than 80% of the heavy oil production , based on the method of injecting steam recovery . Heavy oil recovery process , the steam injection system there are different degrees of energy loss . Note the use of the steam system can situation analysis and evaluation to identify the weak link energy saving technological transformation of enterprises to provide a basis of heavy oil thermal recovery steam injection system thermodynamic analysis . Steam injection system is an important part of the heavy oil development , is also the largest energy-consuming factors . To achieve energy saving , reduce the cost of heavy oil recovery purpose , in recent years , a number of high-tech supporting technology in steam injection system . Through theoretical analysis , the combination of the technical principles and the supporting technology optimization , to improve the economic efficiency of the steam injection boiler operation provides a theoretical basis , and the guidance of steam injection system applications supporting technology . And all aspects of the composition according to the steam injection system characteristics , energy conversion analysis model , given the assessment criteria , and test data analysis calculations . Steam injection system and energy use status based on the analysis and evaluation to identify the weak link of energy , and the causes are analyzed . Finally, research carried out to improve the thermal efficiency of steam injection boiler running from lower steam injection boiler exhaust gas temperature and reduce air coefficient ( oxygen content ) two aspects . In terms of the theoretical analysis , test , design , actual transformation operation and energy efficiency , etc. , have reached the desired effect . The results of this study can be used as the basis for subsequent research , similar guidance .
