Latest Patents

The provided information lists 1 patent for Rui Qian: “Shale Gas Formation Oxidation Induced Rock Burst Stimulation Method.” The method first applies hydraulic fracturing to a shale gas well. During fracturing, it injects slick water A, oxidation fluid, slick water containing glue liquid, catalytic decomposition fluid, and slick water B in sequence using a slug mode.

The method combines shale physical characteristics with chemical thermodynamic properties to calculate fracturing-fluid usage and the radius of the oxidation-induced rock burst. It is designed to mix methane released from the shale after slick-water injection with oxygen generated by hydrogen peroxide decomposition in the oxidation fluid. The resulting formation burst is intended to increase production across multiple fracture scales while maintaining safe, efficient, and damage-free stimulation.
