Mechanism Research for Injection Well Clogging in Shang 3 Region
摘要
Abstract
Shang 3 region in Shanghe oil field has the problem of formation plugging when water injection . This paper addresses the study on theoretical and experimental research of Shang 3 region plugging mechanism and plugging removal techniques .The result show that the injected water quality substandard and injected water is not compatible with the reservoir causes blockage formation .Reservoir rock samples plugging experiment recommends using hydrochloric acid+multi-hydrogen acid+ mud acid system to improve lower members of Es2 .Shrink swelling agent evaluation experiment show that shrink swelling agent can restore formation permeability .Field tests show that hydrochloric acid+low concentration mud acid+multi-hydrogen acid + shrink swelling agent composite plugging process can significantly improve reservoir ,achieve the goal of increasing production and augmented injection .关键词
