Fracturing water injection to enhance oil recovery technology
Solves the conventional water flooding problem in low permeability and unconventional reservoirs; innovates the water flooding measures; improves the water flooding effect; effectively controls the reservoirs natural decline and continuously consolidates the stable production.
Service capability
Optimize the water flooding plan according to the reservoir characteristics and the development situation. Increases the water injection pressure, water injection displacement and driving energy through the large-displacement electric-drive fracturing pump to realize the near-formation breakdown pressure water injection, increase the water driven pressure difference, improve the oil displacement effect of micro-pore throat. By doing this, the water swept area is increased, the water-drive efficiency is improved, and the issue of fast production decline and low recovery of tight oil reservoirs is improved The oil production increase is obvious.
