Due to damage caused by fracturing fluid invasion, tight oil reservoirs exhibit slow post-hydraulic production recovery and low productivity. This study investigates the impact of a nanoclay-based active agent system on oil–water two-phase flow during after emphasizing its potential for enhancing in reservoirs. Laboratory experiments using crude natural core samples analyze mechanism how nanofluids affect distribution characteristics invasion stages. Results show that rapidly disrupt...
Abstract Hydraulic fracturing has a significant effect on increasing production and injection of oil water wells in low-permeability tight reservoirs. Hydrogen sulfide (H2S) was generated after hydraulic Longxi Block Daqing Oilfield. The maximum hydrogen content casing gas reached 232 ppm, far exceeding the safety critical concentration value (20 ppm), which increased risk difficulty construction operation. In order to reveal influence mechanism H2S generation oilfield, experimental...
