【Abstract】 Base on analysis of the problems of polymer injection wells and the inelasticity of fracture in Daqing Oilfield , a new fracture and plug removal technology was put forward. After field application, a better effect was gained, such as the period of validity being prolong, the contradiction between layer being relax. A economic benefit was obtained. This may have a guidance function to plug removal in polymer injection wells.更多还原
