A hydraulic well jar accelerator used in a fishing string in conjunction with a well jar. The well jar accelerator includes inner and outer cylindrical assemblies movable longitudinally relative to each other and having an annular space between the cylindrical assemblies. An annular seal and an expansion sleeve disposed between the cylindrical assemblies are longitudinally spaced relative one another to form an annular liquid chamber in the annular space. The annular liquid chamber confines a hydraulic operating fluid. The volume of the annular liquid chamber can be adjusted by spring-loading the expansion sleeve without relative longitudinal movement of the inner and outer assemblies. The annular liquid chamber is operatively segregated into a main liquid chamber and an expansion liquid chamber. An annular seal body and an annular piston are disposed between the cylindrical assemblies in the annular liquid chamber.

A blow-out preventer for attachment with a tubular member of a well for containing well pressures within the well as needed, having a body adapted to receive a ram body mounted therein for movement between an open and closed position. The preventer further includes an actuator body member mounted with the body adjacent the ram bore and having urging means therewith for urging the ram body between such open and closed positions and alignment means with the actuator body member and the ram body for ensuring proper alignment and positioning of the ram body with respect to the ram bore and the axial bore of the tubular member. The actuator body member has fastening means that fits into connecting means in the preventer body. The two bodies are secured by securing means installed in said connection means and engaging said fastening means.

A casing scraper which provides substantially 360. degree. of contact between the interior diameter of casing. The cutter blades of the casing scraper are of a segmented tubular shape to provide a substantially 360. degree. contact area. The segmented cutter blades are biased radially outwardly by springs oriented in an alignment housing between the supporting mandrel and the cutter blades.

A hydraulic jar for applying a jarring blow to an object stuck in a well wherein two separate annular fluid chambers are provided in the jar, with one of the chambers confining a body of operating hydraulic fluid and means for restraining relative longitudinal movement of the jar for developing tension and stretch in the drill string so as to produce the jarring blow, and with the second annular fluid chamber confining a body of heavy lubricating fluid and splined portions and jarring surfaces to isolate foreign particles from the operating fluid chamber to prevent or inhibit internal jamming or sticking during actuation. Because the means disposed in the operating fluid chamber are subjected only to forces developed during the pulling stroke, the operating fluid chamber may have a greater area for the development of greater pull loads at lower hydraulic pressures than prior hydraulic jar.

A fail-safe mechanism for closing the rams in a conventional blowout preventer. The mechanism includes a ram shaft having an enlarged outer end that is exposed to well pressure which exerts a constant closing force. The closing force is opposed by a hydraulic fluid chamber which is evacuated in the event of fire, etc. A floating plug within the ram shaft helps prevent leaks of well fluid from the blowout preventer.

A new and improved seal for an overshot and method for doing same wherein the seal includes a seal ring body mounted with the overshot, the seal ring body having a first and second sealing lip formed therewith and extending inwardly into the bore of the overshot, with the first sealing lip for initially engaging the tubular member to reduce fluid flow therebetween and the second sealing lip, spaced above the first sealing lip, for establishing a fluid-tight relation between the second sealing lip and the tubular member for preventing fluid flow therebetween.

An improved hydromechanical drilling jar for applying upward and downward jarring blows to an object stuck in a well wherein the jar comprises a mechanically operated jar section which is connected with a hydraulically operated jar section by flexible tubular connector means for providing flexibility therebetween for relieving bending moments on the jar sections during use. The jar sections are separable for ease in storage and transportation and may be relatively positioned in a drill string as desired.
