Adaptability Study and Effect Evaluation of Work Damage Unplugging Technology

In the process of oilfield development, reservoir can be polluted by well cleaning, pump inspection and other operations. And that will lead to a long recovery period oil production after operation, even is difficult recover. recent years, unplugging transformation technologies have been researched applied, certain results achieved. However, there lack systematic evaluation analysis on applicability, advantages disadvantages various technologies. For this reason, application effect existing technology systematically analyzed evaluated in terms formula agent, process, damage mechanism, oil-water relationship, layer aspects means combination geology engineering. The adaptability obtained, it used as principle selection for subsequent technical further improve measures.
