摘要

The filtration and damage characteristics of modified dry CO₂ fracturing fluid in the shale is studied in this paper. The results show that the modified dry CO₂ fracturing fluid has good leak-off characteristics. Compared with liquid CO₂, supercritical CO₂ has a better permeation and diffusion capacity in the porous medium. The damage rate of the modified dry CO₂ fracturing fluid to shale core is only between 0.63%∼3.84% with obvious little damage. Under liquid conditions, the increase of temperature makes the fracturing fluid more harmful to shale formation.
