    • A retrievable bridge plug used in oil and gas wells comprises a setting and anchoring mechanism, a locking and releasing mechanism and a sealing and anti-adhering mechanism. The bridge plug in which a self-locking mechanism is placed can be lowered through an oil tubing or wireline and provide reliable bi-directional sealing , and can be taken out by a special tool after setting in order to be used repeatedly after simple maintenance . By replacing its mandrel, the bridge plug can be refitted into a squeezing bridge plug , a conventional bridge plug (mandrel sealing) or a hook-wall bridge plug (mandrel through) to be used in a temporary/permanent and selective blocking operation. Also, the bridge plug can be associated with other downhole tools to perform well test, layer protection and well killing.
