Interfacial Properties of Novel Polymer for EOR
Hu Qiuping(Oil Production Technology Institute,Shengli Oilfield Company,Sinopec,Dongying 257000)
A novel polymer for EOR was synthesized which was graft polyacrylamide,an active monomer was inserted into the polymer,which was synthesized independently.The results showed that the interfacial tension between polymer and simulative oil could reach the level of 10-2 order of magnitude.It could satisfy the requirements of oil displacement and oil washing simultaneously.Interfacial shear viscosity between polymer and simulative oil was investigated.With the increase of shear rate,the interfacial shear viscosity remained stationary.It showed that polymer did not have shear thinned behavior and shear thickened behavior.It was profitable to demulsification of production fluid.
