[Abstract]:In order to adjust the fuel structure and solve the problem that the equipment used in the field of oil-gas gathering and transportation ground processing station can not meet the thermal energy demand of the station, the medium and boundary conditions of the usual heating equipment in Shengli Oilfield are investigated and analyzed. The problems occurred in the field engineering application of steam or hot water and water containing crude oil (containing or without polymer) are studied and compared in detail. It is found that the heating furnace is the most stable, the suitable interface is wide, and the single coil heat exchanger is suitable. The steam mixing device can effectively solve the problem that the helical plate heat exchanger can not meet the demand of heating load of polymerized crude oil when the heat medium is steam, but there is a high dependence on the external heat source. In the design process of the east secondary heating system reform project in Gudong Oilfield, the requirements of safety, low investment and low operating cost are considered comprehensively, and the characteristics of the internal structure of the water jacket furnace and the single coil heat exchanger are combined. Combined with the control of inlet temperature, pressure and outlet undercooling of heat medium, the control of flow rate of cold medium, the adjustment of equilibrium distribution system of steam, and the volume control of water phase in shell program, the heat transfer between steam and polymer crude oil can be realized. The heat transfer and heating test device is designed and the steam inlet distribution pipe structure is improved after the pilot test in Gudong Oilfield so that the steam entering device can distribute evenly without dead angle. The structure of the inlet and outlet of the coil tube is improved to control and clean each group of coils separately outside, and the flue baffle is added to reduce the heat loss. The improved equipment is used in the whole East double heating system and is running well at present.
