Several Reflections Based on the Corrosive Inspection of Acidifying Fluid

After an introduction to the developing history and technological status of acidifying technology in Daqing Oilfields,an analysis focuses on the problems and phenomenon existing in the corrosive inspection of acidifying fluid in Daqing oilfields in the past few years.While explaining the irrational usage of inhibitor and the hazard of pitting corrosion,the paper also introduces the current commonly-used single type and mixed type of inhibitors,the acidifying fluid types that inhibitor adapts to and the well kinds that inhibitor adapts to.Then several suggestions are put forward about the dosage of inhibitors,the selection of acidifying fluid additives,the mixing of acidifying fluid and supervision.This study is of instructive significance in improving the quality of acidifying fluid products,reducing the second hazard caused by the stratum,increasing the service life of construction device and pipes,cutting down the construction accidents and raising the performance price ratio of acidifying products.
