Abstract

Abstract: Linpan heavy oil reservoir is dominated by conventional heavy oil with viscosity of 1 350~11 980 mPa·s (at 50℃). In view of such problems as high water cut, low production, low recovery, etc, the self-emulsification viscosity reducing technology was studied to solve these problems. The viscosity reducing agent was firstly optimized in the lab, then the influences of temperature, concentration, salinity and reaction time on the oil displacement efficiency and the physical model displacement were evaluated, and finally the viscosity reducing agent for this oilfield with low temperature and high salinity formation condition and its implementation condition was obtained. The small field tests show that MB-5034A agent can be used to effectively enhance the recovery of Linpan heavy oil
