Abstract:

According to non-radial flow characteristic of fluid in formation after acid fracturing treatment, this paper has developed a steady flow mathematical model expressed in dimensionless pressure, and proposed a difference method for calculating stimulatiou ratio. The method all-sidedly considers influences of well-bore damage from well boring and well completion, fracture-wall damage from acid fracturing treatment, and finite fracture conductivity. It can be used to calculate the stimulation ratio of an acid fracturing well accurately.

Key words: Formation damage, Fracture conductivity, Acid fracturing, Production prediction, Mathematical model, Calculating method
