Abstract

The threshold pressure gradient of CO₂ miscible flooding is very complex in the low permeability reservoir. And the short low permeability core experiments are adopted to study it in this paper. Studies show that the curve of pressure gradient and flow rate presents a concave distribution and the threshold pressure gradient is found. Under the same conditions, the threshold pressure gradients are ranked as an order. The threshold pressure gradient and core permeability / fluid mobility bases on a power function. And the fluid viscosity is one of the main factors affecting the threshold pressure gradient.
