Abstract: Given the high temperature and high salt conditions in Tahe Oilfield,in which the reservoir temperature is at 140℃ and formation water salinity is 2.4×105 mg·L-1,SDQ-1,a temperature- and salt-resistant weak gel displacement agent,is developed for tertiary oil recovery.The temperature resistance,salt resistance and displacement performance of SDQ-1 system are evaluated.The results indicate that SDQ-1 has good thermal stability and salt tolerance,and its viscosity retention rate can reach 81.8% under the condition of formation water in Tahe Oilfield.Study on visual displacement evaluation device shows that SDQ-1 system can significantly reduce the finger-advance phenomenon during water flooding,and the effect of recovery efficiency is improved with the increase of viscosity.
