儲(chǔ)層損害
During oil production, sand production in loose sandstone reservoir because of fluid washout often causes formation damage and production drop, sometimes as worse as casing damage and well abandonment.
石油開(kāi)採(cǎi)過(guò)程中,由於水動(dòng)力的沖刷等作用引起的疏松砂巖儲(chǔ)層出砂,會(huì)導(dǎo)致儲(chǔ)層損害和産能降低,甚至造成套琯損壞、油井報(bào)廢。
