Basic Property Research of Heavy Oil in Northwestern Tahe Oilfield

Abstract

Abstract: The Block 10 and Block 12 in northwestern Tahe field are characterized by high density （0.95~1.09 g/cm³）, high viscosity （700~1 800 000 mPa·s）and strong heterogeneity, which restrict the efficient development due to the big difficulty of viscosity break. This paper studies the basic properties and group components of crude oil from several 10 wells and analyzes the affecting factors of such a high viscosity. This will be as a guide for effectively taking viscosity break measures in this area in future.

Key words: Tarim basin, heavy oil, group component, colloid, bituminous matter
