Abstract
Temporary plugging technology is one of the valid methods of reservoir protection during the workover job. From the Lab valuation of the optimization of oil dissolve resin temporary plugging agent (ODRTPA), this paper studies the main factors which effect the restoring rate of formation permeability, such as the rate of oil dissolve, the particle diameter of temporary plugging agent, formation temperature and permeability, temporary plugging pressure and time, retemporary plugging and so on. At the same time, this paper also researched the valid temporary plugging time, deepth and strength. A suit of lab evaluation method of ODRTPA was set up, which can provide technology guide to field practice.
