“…It is a long way and there is secondary pollution. In recent years, many oilfields have carried out research on the technology of sludge profile control, through chemical treatment of sludge to prepare profile control agent used in water injection wells, can achieve the treatment of oil-bearing sludge and improve the effect of water injection development, it is an economical and effective sludge treatment method [1][2][3][4][5][6][7][8][9][10][11][12] . However, due to the uneven particle size of oily sludge, poor suspension, low plugging strength and other factors lead to poor field application effect [13][14][15] .…”

In order to solve the problems of difficult injection and easy secondary recovery of oil-bearing sludge for profile control, the micro-morphology and composition characteristics of oily sludge in Jidong Oil Field were determined and analyzed by SEM. The influence of different dispersants on the dispersion characteristics of oil sludge was analyzed. The optimum dosage of dispersing agent Na 2 CO 3 is 0.8%-1.0%. The effects of 4 kinds of suspension agents on the suspension performance of oily sludge were analyzed by rheological experiments. The suitable suspending agent and its dosage were determined, and on this basis, the oil sludge gel particles profile control system was made by adding gel-forming and initiator. The salinity resistance and viscoelastic properties of oil sludge gel profile control agent was measured, and the effect of profile control was evaluated by physical simulation experiment.The results showed that the oily sludge gel particle profile control system has good resistance to different salinity,better viscoelastic and good plugging properties. The field test shows that the total oil increment of sludge profile control is 2568t.
