In view of the high solid phase content of oil-containing sludge and the lack of treatment conditions in the Zhundong oilfield，combined with the need of cracked oil storage wells，three different strength oily sludge profile agents were prepared by adding thickening agents，cross-linking agents and curing agents，and its suspension performance，blocking performance and curing strength were evaluated. The results showed that solid-phase particles of oil-containing sludge in the Zhundong oilfield， which was smaller than 425 μm，could be carried into the formation，and the utilization rate of sludge was more than 90%. The suspension time of a sludge suspension system，composed of 30% oily sludge + 0.3% thickener was greater than 60 min. The sludge gelling system，composed of 30% oily sludge + 0.3% thickener + 0.2% crosslinker，had good temperature，salt resistance performance and shear resistance. The gel strength changed little at the temperature of 40—90℃ and beyond the mineralization degree of 50 g/L，the gel strength was 26.8 Pa·s at the formation temperature of 55 ℃. Core flow experiments showed that the gelling system had over 85% plugging rate，and over 6.8 MPa breakthrough pressure. The pressure strength of the sludge curing system，composed of 30% oily sludge + 0.3% thickener + 0.2% crosslinker + 0.6%—0.7% curing agent，was 4.6 MPa. The strength of the three sludge systems was different，and the combined use could achieve effective sealing of fractured reservoir. The oily sludge profile system was applied On-site scale for 36 wells，cumulative treatment amount of oily sludge was 31186 m³，saving sludge treatment costs of 15 million yuan，well group cumulative oil increase was 7956 tons. As a result，the oily sludge profile system not only improved the effect of oil field development，but also realized resource utilization of oily sludge.
