Combination well clean-out tool and jar
Patent
·
OSTI ID:6218085
A well cleanout tool for retrieving junk or debris from the bottom of a borehole is described. The tool may be run into an oil well on the end of a wire line. Included within the tool are various chambers for retrieving or holding junk which flows in when a valve is actuated. A combination valve actuator and jar mechanism is manipulated by the wire line and facilitates removal of the tool from the borehole when it becomes stuck. A relief valve in the form of a resilient one- way check valve progressively reduces the internal pressure of the tool after it has been actuated and is traveling uphole. A second jar mechanism is optionally provided at the lower extremity of the tool. (9 claims)
