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...
