| Abstract: | A new wax deposition inhibitor,SZ-3,is developed for downhole use in crude production in Zhuangxi Oil Field.Shengli. The crude is of high wax(24-46%) and resin contents and of high pour point and viscosity.SZ-3 is an O/W emulsion with EVA copolymer solution in toluene(oil phase) and aqueous system of a water-soluble nonionic surfactant and a low MW alcohol and prepared by an oil-soluble surfactant.The wax deposition inhibition,pour point depression and viscosity reduction cause by SZ-3 in different use level are investigated.The results of successful field tests are presented. |
