Acid diversion treatments in injection wells using permeability modifiers |
摘要 |
Some embodiments herein comprise providing a treatment fluid comprising an aqueous base fluid, an acid, a permeability modifier, and a permeability modifier deactivator; providing an injection well having a first treatment zone comprising a first aqueous formation permeability, wherein the first treatment zone comprises formation damage; introducing the treatment fluid into the injection well, so as to contact the acid, the permeability modifier, and the permeability modifier deactivator with the first treatment zone; reacting the acid with the first treatment zone so as to repair a portion of the formation damage; reacting the permeability modifier with the first treatment zone so as to cause the first aqueous formation permeability to adopt a second, lesser aqueous formation permeability; and contacting the permeability modifier deactivator with the permeability modifier so as to deactivate the permeability modifier and restore the first treatment zone to about the first aqueous formation permeability. |
