The problems of low recovery rate of adsorption tank,low desorption efficiency of absorption tower,high energy consumption of oil and gas recovery system and many potential safety hazards in the oil and gas recovery process caused by high temperature in summer of oil depot were studied.Methods The lower temperature groundwater is used as cooling water,and a variety of shell-and-tube heat exchangers with enhanced heat transfer structures are constructed from the practical point of view,and their thermodynamic and hydrodynamic performances are investigated in various aspects by using the CFD method.Results When the oil and gas flow in the shell and tube heat exchanger,the heat flow can get better cooling effect;when the oil and gas flow in the shell and tube,the CIRF type heat exchanger tube has the best thermodynamic performance,and the RAW type heat exchanger tube has the best hydrodynamic performance.Conclusion The shell and tube heat exchanger with CIRF type heat exchanger tube has strong applicability in the oil and gas recovery process,which can effectively improve the cooling effect of oil and gas while taking into account the hydrodynamic performance of the heat exchanger.
