Abstract

Affected by the difference in permeability of the water injection layer, the injection effect of each injection well layer also has a large difference, the formation permeability gradually decreases, the water injection volume also decreases, the low permeability reservoir has poor reservoir property, the oil well production is low, and the injection well water injection pressure is high and the water injection is difficult. The injection volume of the low permeability layer must be increased by the water injection well fracturing technology. The main function of the water injection well fracturing technology is to improve the water flooding volume, water absorption capacity and oil production capacity of the water injection well, and improve the oil layer utilization condition by supplementing the reservoir energy to achieve the goal of increasing single well production and even the overall block production. This paper mainly discusses the application of fracturing technology in water injection wells in low permeability reservoirs.
