Abstract: Alternative water shutoff agents comprising TDG-IR and TF-3 as main components are presented.Also presented are the studied relevant factors affecting the performance of water shutoff agents.Both sirnulations of reservoirs physicochemical conditions and tests in-site of oilfields prove that this type of water shutoff agents has the alternative of water and oil and the high compressive strength and low viscosity of base liquid during the water shutoff job.They were also proved to be capable of carrying all kinds of solid filling materials and adapting themselves to a broad range of temperatures,to have the possibility of readjusting gelification time and the simplicity of application process and the relatively long effective period.They represent today a new type of domestic water shutoff agents with better performance.
