As one of main waste materials in petro-plant, oily solid waste presents a serious disposal problem which puzzle petro-plant. With the sanity of decrees and statutes enhanced and protective circumstance consciousness strengthened, the oily sludge treatment has more and more been becoming an important issue, and people think more of it for overcoming the problem. Nowadays the method of harmless treatment of the oil in sludge in oilfield has been an important scientific research task.With analyzing the composition and particle size of oil-bearing solid waste, a new profile control agent was developed by using the oil-bearing solid waste as main material and adding chemical agents and solid particles. Entirely performance evaluating experiments show that: surfactant sludge controlling agent has good thermal stability, anti-shearing, anti-pollution. Results of plugging experiments show that: when adding quantity is nearby 8%, the plugging ratio can get 94%.On the base of experiments in laboratory and study of numerical simulation, we take the forerunning test of technical study of oily sludge depth injection profile adjustment in xing93 fault block in 2006, accumulative totally increase gas production by2864t, totally devotion to outputting ration get 1:3. We take whole deep profile controlling in xing203,206 fault block and xing228 rejection well group, and get good results. Up to April,2009, these have accumulative totally increase oil production by 12948t, get directly economic benefit to $1051.16×10~4 yuan. At same time, downrightly put away 3850m3 oiliness mud stockpiled in xing1 and xing2 combined transfer station then showing out apparent economic and social benefit.The technique not only effectively resolves the environment pollution problem made by letting out of oiliness mud, but also offer a new kind of technique for integrate father in oilfield and decreasing production cost, it has far-ranging practicality applying value.
