The Qinhuangdao 32-6 oilfield, Bozhong 25-1 block of Shahe Street group of deep buried reservoir, diagenesis degree is high, and the Minghuazhen reservoir with low porosity, permeabilitycompared, less serious, plugging of oil wells. This paper adopts a new environment-friendly oilcleaning technology, relying on the "efficient organic solvent", to the near wellbore wells squeezeefficient organic solvent use piston pump, dissolve, disperse asphaltene to clean the near wellbore zone, oil well recovery yield, through the Qinhuangdao 32-6 oil well operation results show that, the single well production increase rate of more than 200%, remarkable economic benefit.
