Research and Application of Hydraulic Pumping Bridge Plug Fracturing Technology in Oil Wells

摘要

Horizontal well volume fracturing is the main technology for developing low permeability reservoirs,but the conventional multistage fracking technology has not fully meet the needs of volume fracturing process.Hydraulic pumping bridge plug and perforating staged fracturing technology uses pressure associated with bridge plugs for conduct bridge into a predetermined position horizontal section through the pump plug fracturing perforating,fracturing increases the volume efficiency.Experiments of 86 wells were carried out in Longdong area of Changqing in 2018.Tests showed:hydraulic fracturing technology has pumped bridge plug packer reliable,unlimited series of staged fracturing,fracturing short cycle characteristics.Hydraulic fracturing pumping bridge plug successful implementation,initially explored the block for an effective reservoir stimulation techniques,Longdong area for the next large-scale,high-volume fracturing has accumulated valuable experience in the field.
