【Abstract】 The new-style hepta-block copolymer polyoxyethylene-polyoxypropylene polyether phosphate ester demulsifiers is prepared for dehydrating high water cut and viscous heavy crude oil of district X of Shengli Oil-field Gudao Oil Production Factory. In a series of laboratory experiments these water-soluble demulsifiers are superior to those demulsifiers used at present in dehydration rate, demulsifying rat and separated water quality, distinct oil/water interface. With BPE7-P4 # in 0.01% at dehydrating temperature 60℃,qualified crude of water content ≤0.5% and separated produced water of oil content 0.038% are obtained.更多还原
