Experimental Study on Reducing the Reverse Phase Point of Water Cut Crude Oil with Flow Improver

Based on the fact that the rheological characteristic will be changeable with the growing of the water percentage of the water-content oil which is transported through oilfield pipeline networks, experimental studies are made in the level pipe equipment by adding DODE improver into the water-content oil for the purpose of finding out the law that DODE improver affects on the water percentage and viscosity. The result shows that adding DODE improver into water-content oil can make the reverse phase point reducing to 35%~45% and form stable emulsion earlier, and improve the low temperature fluid ability and also reduce the appearance viscosity of the crude oil and get energy consumption obviously.
