Research and Application of Active Nanometer Power Blowdown and Stimulation in Es_3~(middle) 6~10 Reservoir of Pucheng Oilfield

In allusion to the problems of formation damage and injected water pressure increase induced by poor water quality in Esmiddle3 6~10 reservoir of Pucheng Oilfield, the causes of problems were analyzed, a blowdown and stimulation technique using active nanometer was proposed, laboratory experiments were conducted on it. Study shows that the nonometer technique is feasible. The nonometer acidizing technique is used in 10 wells, the result indicates that it is effective and can be used in oilfield production.
