Through the low temperature dewatering test of Daqing South seven joint station, several low temperature demulsifiers were evaluated and evaluated. The technical and economic effects of low temperature dewatering and low temperature dewatering using energy saving and reducing oil and gas depletion were discussed. The crude oil In entering the high water cut stage to take the significance of low temperature dehydration.
