| Abstract: | 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. |
