Improved water washing treating-agent and method for realizing standard oily sludge treatment in oil field by employing same

The invention discloses an improved water washing treating-agent and a method for realizing standard oily sludge treatment in an oil field by employing the same. The improved water washing treating-agent comprises the following materials by weight: 2 to 8 parts of sodium hydroxide, 5 to 10 parts of sodium dodecyl benzene sulfonate, 1 to 5 parts of sodium carbonate, 1 part of polysorbate, and 82 to 85 parts of water. Due to the use of the improved water washing treating-agent and water, oily sludge can be decomposed into an oil phase, a mud phase and an aqueous phase, and the materials are low in cost. The method is simple and feasible in application, and can be used for further reducing the energy consumption and the cost of decomposing of oily sludge into the oil phase, the mud phase and the aqueous phase, and further obviously improving the timeliness of oily sludge treatment.
