| Abstract: | The mechanisms of formation blockage were analyzed. The principles of newly developed high pressure water jet technology combined with acidization for treating perforations and formations near wellbore are introduced. The applied results of thirty oil wells and water-injection wells in Shengli Oilfield and Huabei Oilfield indicated that this technology is characterized by simple procedure, high success ratio, wide feasibility and remarkable effectiveness. It has a good prospect in the application of production increment and augmented injection as well as enhanced oil recovery. |
