Abstract: An apparatus for use in a wellbore comprises a housing having a longitudinal axis and a mechanism having one or more impact elements adapted to move along the longitudinal axis in an oscillating manner to impart a back and forth force on the housing to vibrate the housing. In another arrangement, an apparatus for use in a wellbore comprises a housing and at least one impact element rotatably mounted in the housing. The at least one impact element is rotatable to oscillate back and forth to impart a vibration force to the housing.

Abstract: A jarring and bumping tool is provided, having a mandrel telescopically received within a barrel for relative longitudinal movement. Upper and lower seals form an oil-containing annular space therebetween. The mandrel carries a free-floating annular primary piston which sealably engages a reduced-diameter piston fitting section of the barrel when passing therethrough. The mandrel also carries a secondary cylinder assembly with a transverse top wall and a downwardly extending annular secondary cylinder beneath the primary piston, forming a piston chamber between the mandrel and secondary cylinder assembly. The mandrel also carries a spring which biases a free-floating annular secondary piston upwards into the piston chamber. A port through the top wall of the cylindrical member provides fluid communication between the annular space and the piston chamber. Thus, when the mandrel is pulled upwards the primary piston seals against the piston fitting section, oil in the annular space is compressed and forced through the port and into the piston chamber against the secondary piston to compress the spring, and the drill string is stretched. When the primary piston clears the piston fitting section, fluid moves rapidly around the primary piston, the mandrel extends, and impact faces connect to deliver a jarring stroke upwards.

Abstract: A single acting hydraulic fishing jar, for use in a tubular drilling string for applying upward jarring forces for dislodging a "fish" from a well, may be run into a well on a drill string to operate a fishing tool in the well bore. The jar has housing members in telescoping relation for longitudinal movement of one relative to the other with a hammer member on one and an anvil member on the other. The housing members enclose a chamber containing an incompressible hydraulic fluid for controlling application of jarring forces. A sliding seal closes one end of the chamber and supports the inner housing member, i.e. mandrel, for sliding movement in the outer housing member. A piston is spaced from the sliding seal so that movement of one relative to the other. Movement of one housing relative to the other in one direction moves the piston toward the sliding seal. The chamber between the piston and the sliding seal has an outlet controlled by a valve member slidably supported for movement on the mandrel. Predetermined relative movement of the housing members engages and moves the valve member to open position permitting flow of fluid from the fluid chamber to substantially eliminate the resistance to further movement of the housing members and thus permit movement of a hammer member on the mandrel to impact an anvil member carried on the outer housing.

Abstract: Disclosed is a bidirectional fluid operated jarring apparatus. The apparatus includes a tubular body having a lower end defining a downwardly facing body hammer. A tubular knocker sub is axially slidingly mounted to the body adjacent the body hammer and includes an upwardly facing anvil engageable with the body hammer and spaced apart oppositely facing internal hammers, the upper one of which defines an internal anvil. A tubular mandrel having a low passage therethrough is axially movably mounted in the body and knocker sub. The mandrel includes a hammer positioned within the knocker sub between the internal shoulders. A valve is provided for closing the mandrel flow passage so that fluid pressure urges the mandrel axially downwardly with respect to the body and opening the mandrel flow passage upon predetermined downward movement of the mandrel. When the knocker sub is in a retractive position, the apparatus produces a downward jarring force. When the knocker sub is in an extended position, the apparatus produces an upward jarring force.

Abstract: A double acting hydraulic drilling mechanism, i.e. drilling jar, is disclosed for use in a tubular drilling string for applying upward or downward jarring forces for dislodging a "fish" from a well. The jar is adapted to be run into a well on a drill string and connected to a fishing tool in the well bore. This jar comprises outer and inner housing members positioned in telescoping relation for longitudinal movement of one relative to the other and having a hammer member on one and an anvil member on the other. The housing members enclose a chamber adapted to contain a fluid for controlling application of jarring forces. A pair of pistons are positioned in spaced relation for movement of each relative to the other in the hydraulic fluid chamber. The pistons are arranged so that movement of one housing relative to the other in one direction will move the first piston toward the second and movement in the opposite direction will move the second piston toward the first. The chamber between the pistons has an outlet controlled by a suitable valve member. Valve actuating means are provided which are operated upon predetermined relative movement of the housing members in either direction to open the valve to permit flow of fluid from the fluid chamber to substantially eliminate the resistance to further movement of the housing members and thus permit movement of a hammer member into engagement with an anvil member with an impact force. An alternate embodiment utilizes one or both pistons in a dash-pot action in lieu of the valve member permitting fluid flow from the fluid chamber.

Abstract: There is disclosed a hydraulic jarring device in which an impediment mechanism for controlling the movement of a mandrel with respect to a barrel is exposed to a fluid pressure which is significantly reduced from that pressure generated by the tensional load applied to the jarring device by the hoisting apparatus used to recover an object lodged within a well bore. The impediment mechanism, in one embodiment, is actuated by one or more hydraulically operated plungers slidably mounted within the housing of the jarring device. The plungers cooperate with a control sleeve whose movement is in turn controlled by a metering valve operating at a pressure significantly less than that above the plungers, and having an effect on movement of the sleeve inverse to the tension generated by the hoisting apparatus. The metering valve, in one embodiment, comprises a movable helical plug having a needle nose which associates with a valve seat to control fluid flow. Upon the control sleeve reaching a predetermined position in its stroke, pressures are relieved and a hammer associated with the mandrel impacts against an anvil associated with the barrel.In another embodiment of the impediment mechanism, the hydraulically operated plungers are replaced by helical springs. Also disclosed is a metering valve wherein the helical plug is replaced by a generally linear hydraulic choke.
