Abstract:

This paper established an evaluation method for oil-soluble polymer viscosity reducing agent to heavy crude oil. The viscosity reducing agent was synthesized in laboratory and evaluated effects of diluent, mixing time, storage temperature and storage time on the viscosity reduction of crude oil. After inspection found that the evaluation methods have a significant impact on the viscosity reduction ratio. The maximum stable viscosity reduction rate can be obtained under optimal conditions. In the conditions of kerosene as diluents (ratio of 9:1), mixing time of 40 oC, storaged at 50 oC for 10 h, the viscosity reduction rate of 87% was achieved. The viscosity reduction rate can truly reflect the actual viscosity reduction ratio. This method can accurately determine the rate of viscosity reduction reducing agent for such other researchers evaluated in this method, the rate of viscosity reduction obtained is comparable in different labs.
