油水两相黏度调节剂的制备和驱油效果
Preparation and oil displacement performance of oil-water biphasic viscosity modifiers
摘要
Abstract
Viscosity modifiers for oil-water two-phase systems were prepared in high-salinity formation water using erucic acid amidopropylamine oxide(EAPO)with aqueous-phase thickening properties,hexadecyl-octadecyl hydroxypropyl sulfobetaine(HSB)and hexadecyl hydroxypropyl sulfobetaine(HSY)with weak power to emulsify heavy oil.The aqueous-phase thick-ening performance,emulsification effect,and oil displacement efficiency of the system were investigated.The results show that the viscosity of 0.3%EAPO/HSB and 0.3%EAPO/HSY mixed system can be higher than 15 mPa·s when the mass fraction of HSB or HSY is 0.03%-0.1%,and the heavy oil can be effectively emulsified at rotational speeds below 100 r/min.In particular,the mixed systems of 0.3%EAPO/0.07%HSB and 0.3%EAPO/0.07%HSY reduce the viscosity of e-mulsified heavy oil to 6.32 mPa·s and 15.76 mPa·s,with viscosity reduction rates of 95.58%and 88.98%,respective-ly.Owing to the dual functions of aqueous-phase thickening and oil-phase emulsification viscosity reduction,the injection of 0.6VP of the 0.3%EAPO/0.07%HSB mixed system enhances heavy oil recovery by 17%.关键词
