After a long time of depletion production and bottom water coning, the YT1 Fault Block in Tahe Oilfield has generally entered the high water cut stage. Conventional measures such as gas lifting, drainage and gas production have failed in some case, and water plugging has become the main replacement in the later stage. Based on the water plugging experience of Tahe Oilfield, the relative permeability adjusting agent is took as the main research and development direction, and forms the emulsified oil plugging agent is formed based on the medium dilute oil and the “anion+non-ion” compound emulsified system of Tahe Oilfield. Under the formation condition, the viscosity reaches 50~60 mPa·s, causing low damage to the reservoir. Through the single and double sand filling tube displacement experiments, it is found that the water-phase plugging rate of the emulsified oil system is 83.4 %, and that for oil-phase is only 11.9 %. Therefore, it has better erosion resistance, oil-water phase selectivity and formation permeability adjustment ability. The slug of water plugging process by emulsified oil is designed as "dilute oil acted as isolation fluid+emulsified oil system+dilute oil acted as isolation fluid+clear water displacement fluid", without moving the string, and with 1~2 days’ soaking, to implement 1~2 rounds. The field application has a good water plugging effect, providing an important guiding for the similar condensate oil and gas reservoirs in water plugging
