Research Progress and Applications of Preformed Particle Gel

Laboratory studies and field applications of preformed particle gels(PPG) were reviewed with 48 references.This paper focused on improvements in preparation methods of PPGs(including progress in heat-resistant, salt resistant, and swelling rate controlled ability).Profile control treatments of PPGs in high-salinity, high-temperature reservoirs, thick low-temperature, low-salinity sand formations, polymer flooding reservoirs, and fractured reservoirs were presented in details.The future development was prospected as well.
