摘要
Abstract
Changqing Oilfield has nearly 3 000 water source wells,and relying on these wells for geothermal utilization has great potential for development.Selecting a typical station in Changqing Oilfield,the geothermal utilization process of"water intake and heat transfer+direct heat exchange"for water source wells.The economic evaluation is carried out based on the influencing factors of geothermal water outlet temperature,geothermal water volume,and geothermal water salinity,at the same time,the economic boundary conditions of hydrothermal geothermal utilization are clarified,providing reference for the feasibility study of geothermal utilization projects in water source wells.The results indicate that,with other influencing factors remaining constant,the economic viability of the project is positively correlated with the temperature and flow rate of geothermal water,and negatively correlated with the material price of the heat exchanger.When the geothermal water outlet temperature is 32℃and the geothermal water flow rate is 210 m3/d,a comparative analysis of the prices and maintenance costs of evaporators made of carbon steel(actual working conditions),254SMO stainless steel,2205 duplex stainless steel,and titanium shows that carbon steel is more economical.关键词
