Through an overview of the water injection system and its importance in unblocking,the mechanism of oil reservoir plugging in water injection wells is analyzed,including factors such as clay swelling,iron precipitation,and bacterial plugging.New water injection technologies such as blowout prevention,pressurization,plugging technology and water flooding development models are introduced,and advanced water injection strategies are proposed,such as the combination of vertical well water injection and horizontal well production.Through practical points,the optimization measures for oilfield water injection development are summarized,including adjusting well patterns,implementing layered water injection,improving water injection quality,and accurately controlling water injection pressure.
