A New Composite Viscosity Reducer for Abnormal Low Temperature Extra-Heavy Oil Reservoir with High Acid Value

M7 block of Santanghu oilfield is an abnormal low temperature tight oil reservoir. The effective development is very difficult. In this paper, we develop a new composite viscosity reducer called CSY-1. The synergistic effect of these agents provides the reducer with both dispersion and emulsificatio...
