摘    要:通过室内试验,研究了临南油田注水井伤害机理。结果表明.造成该油田注水井堵塞的原因有:固相颗粒堵塞、注入水与地面水不配伍形成无机垢堵塞、细菌堵塞。针对注水井储层伤害.采用油层保护技术,进行水质改造,实施合理的解堵工艺,来延长解堵增注措施有效期,经现场应用后效果显著。

关 键 词:注水井  注入水  地层损害  解堵  增注  临南油田

Abstract:Damage mechanisms of injection wells in Linnan Oilfield is studied through laboratory experiments. The result shows that the causes of the injection well damage in the oilfield include solid particle blocking, inorganic scaling blocking induced by incompatibility of injected water with surface water and bacterial blocking. In consideration of formation damage in injection wells, reservoir protection technique is used to improve water quality, implement reasonable broken down technique to prolong the validity of broken down stimulation, the results is obvious in field application.
Keywords:water injection well  injection well  formation damage  broken down  stimulation  Linnan Oilfield
