【Abstract】 For solving serious, problems of the regular profile control and acid treatment in improving profile of the water injection well, TD acid-proof plugging agent was synthesized. The relative indexes was evaluated in the laboratory. According to the comprehensive application in water injection well with CES combination acid, the goal of controlling the high permeable formation, reinforcinglow permeable formation, effectually improving the water absorption profile and getting the satisfied result of increasing oil were achieved. Furthermore, This technology offered a new method for the oil-field developing of the serious anisotropism reservoir.更多还原
