摘　　要：孤岛油田油层胶结疏松,油层污染伤害较重,主要表现为粉细砂、微粒、粘土分散运移污染近井地带充填砂层和防砂管。文中论述了油层伤害的内外因素,提出不同解堵工艺的选井条件,并在生产中运用物理及化学解堵方法取得了很好的效果,获得良好的经济效益。对疏松砂岩类油藏的解堵增注工艺有一定的指导意义。Formation of GuDao Oilfield belong to bullheaded sand consocidation. Pollution of pay zone is serious. This article described the factors of formation damage inside and outside two aspects and put forward well selection conditions for different plug removal tech- nology. We have obtained a good effect in production through applying physical and chemical plug removal method and good economic benefit. It had a guiding meaning for conventional acidization technology in loose sandstone reservior.
