Abstract
Viscosity—temperature characteristics and rheology behavior for heavy oil were measured and researched by using RS75 rotary viscosimeter.The results show that viscosity—temperature characteristics are according with Arrhenius equation in temperature interval (80～20 ℃ ), viscosity is more sensitive to temperature changes in lower temperature, the activation energy rises 40 ％ in lower temperature interval (36.5 ～ 20.3 ℃ )more than in higher temperature interval(80.0 ～ 55.9 ℃ ), and heavy oil is Newtonian fluid above anomalistic point(35 ℃ ), non—newtonian fluid and without thixotropic property below anomalistic point.关键词
