Mechanically Robust and Underwater‐Stable Hydrogels via Synergistic Molecular Locking and Topological Entanglement

ABSTRACT Highly entangled hydrogels typically suffer from swelling‐induced dilution of chain entanglements in aqueous environments, leading to compromised energy dissipation and mechanical integrity. Herein, we report an underwater‐stable and highly entangled poly(acrylamide–acry...

Mechanisms and Parameter Optimization of Pre-Fracturing Energy Enhancement in Ultra-Low-Permeability Tight Oil Reservoirs

Ultra-low-permeability tight oil reservoirs, including the Chang 6 and Chang 8 formations in the Changqing Oilfield and the Fuyu reservoir in the peripheral Daqing Oilfield, are characterized by poor reservoir properties and limited waterflooding efficiency. Conventional areal wa...
