Research status and development suggestions for foam fracturing technology
Compared with conventional hydraulic fracturing technology,foam fracturing te-chnology can greatly reduce water consumption by using foam as fracturing fluid.Compared with water-based liquid in hydraulic fracturing technology,foam reduces the interaction with formation rocks to a certain extent and reduces the risk of formation plugging.And high vis-cosity foam can better carry proppant,improve the fracturing effect of reservoir,significantly improve the permeability of oil and gas,so as to improve the efficiency of oil recovery.This paper aims to review the research progress of foam fracturing technology and clarify the opti-mization and improvement of foam fracturing fluid in this process.The characteristics and advantages of foam fracturing technology in the development of low permeability oil and gas reservoirs and coalbed methane are analyzed,and its importance and application prospect in the field of petroleum engineering are discussed.Through the research and discussion of this paper,it is expected to provide useful reference and inspiration for the research and applica-tion of foam fracturing technology,so as to promote the sustainable development of petroleum engineering and achieve more efficient and environmentally friendly oil and gas resources development.
