Wireline suspendable apparatus for sealing a subterranean well

摘要: An apparatus and method for preparing a casing of subterranean well injecting sealing mixture therein. The comprises an elongate body extending between top bottom ends connectable to wireline at the having plurality nozzles therethrough proximate bottom. A scrapers within each have first retracted position second radially extended engageable with casing. cavity is operable contain piston movable therein so eject through nozzles. positioning in location be sealed, engage casing, displacing scrape against retracting scrapers. displaced
