    Abstract：Oilfield crude oil storage and annual workover operation may generate a lot of oily sludge. Conducted is analysis on main components of oily sludge and put forward is the idea that oily sludge is used to make profile control system for water injection well profile control. Solids in oily sludge components are fully used to replace particle profile control system so as to reduce oily sludge volume needed to be treated. In indoor experiment, screened are low cost polymer and crosslinking system and their profile system strength is more than 15000 mPa • s with core plugging efficiency of 90%, 3.5% more than conventional profile control system. Simulated are three different modes at site, conducted is the plugging experiment and selected is the optimal injection mode from design methods to form the whole block profile control scheme. Optimized are design parameters, implemented is field test in 5 wells of Xinli Oilfield with cumulative treatment of oily sludge 2200 t, income reaches up to 105.4 x 104 Yuan (RMB), the ratio of input to output reaches up to 1:1.5 and economic benefit is very significant.
