摘要： A tool string, such as one used for performing fracturing operations or other types of operations, includes a valve, a valve operator, and a sealing assembly that in one arrangement includes packers to define a sealed zone. The tool string is carried on a tubing, through which fluid flow may be pumped to the sealed zone. The valve operator is actuated in response to fluid flow above a predetermined flow rate. When the flow rate at greater than the predetermined flow rate does not exist, the valve operator remains in a first position that corresponds to the valve being open. However, in response to a fluid flow rate at greater than the predetermined flow rate, the valve operator is actuated to a second position to close the valve.

摘要： A tubing conveyed multi-position well treating tool having a tubular housing and a tubular inner member which are relatively positionable at “Set”, “Treat”, “Dump” and “Release” positions actuated by a mechanical indexing mechanism. The indexing mechanism is loaded by a spring, such as a compressed gas spring or mechanical spring, which urges the tubular housing away from the tubing connection of the inner tubular member, thus requiring no set-down forces for tool actuation or indexing. The treating tool is anchored within the well casing by hydraulic pressure actuated buttons, thus eliminating the typical requirement for anchoring actuation by set-down forces. The treating tool is sealed within the casing by pressure energized packers which are activated by the hydraulic pressure of fluid supplied from the tubing. The tool provides a bypass passage to allow communication of the zones above and below the tool while isolating the straddled interval to be treated.

摘要： A drilling tool, adapted to drill a wellbore in an earth formation, comprises a weight on bit equalizer shock sub. The weight on bit equalizer shock sub includes a precharged nitrogen chamber and additional chambers, the nitrogen in the nitrogen chamber adapted to telescopically open the equalizer shock sub during the drilling of the wellbore thereby maintaining a constant weight or force on the drill bit during the drilling operation. A force resultant from the pressurized nitrogen exists in the nitrogen chamber and additional forces resultant from a pressurized wellbore fluid exist in the additional chambers. The shock sub is specially designed in a particular manner to cause the sum of the force of the nitrogen in the nitrogen chamber and the additional forces of the wellbore fluid in the additional chambers to be equal solely to the force of the nitrogen in the nitrogen chamber. As a result, the weight or force on the drill bit is constant when the sum of the force in the nitrogen chamber and the additional forces in the additional chambers is equal solely to the force of the nitrogen in the nitrogen chamber. In a preferred, second embodiment, when the additional chambers include an atmospheric chamber, the weight or force on the drill bit is constant when the cross sectional area of the atmospheric chamber is equal to the cross sectional area of the nitrogen chamber. As a result, the only force on the drill bit during drilling is the force of the precharged nitrogen in the nitrogen chamber and consequently a constant weight or force on the drill bit is maintained during the drilling operation.
摘要翻译： 适于在地层中钻井的钻孔工具包括钻头均衡器冲击副的重量。 位均衡器冲击副的重量包括预充氮室和附加室，氮室中的氮适于在钻井期间可伸缩地打开均衡器冲击次级，从而在钻孔期间在钻头上保持恒定的重量或力 操作。 在氮气室中存在由加压氮产生的力，并且在附加室中存在由加压井筒流体产生的附加力。 冲击副特别设计成使得氮气室中的氮气的总和和附加室中的井眼流体的附加力的总和仅等于氮气室中的氮气的力 。 因此，当氮气室中的力和附加室中的附加力的总和等于氮室中的氮的力时，钻头上的重量或力是恒定的。 在优选的第二实施例中，当附加室包括大气室时，当大气室的横截面面积等于氮室的横截面面积时，钻头上的重量或力是恒定的。 因此，在钻孔期间钻头上的唯一力是氮气室中预充氮的力，因此在钻井操作期间保持钻头上恒定的重量或力。

摘要： A packer and service tool assembly for oil or gas well preparation includes a disengageable coupling mechanism which permits the tool to be screwed into and out of the packer and which can be hydraulically disengaged so that the tool can be removed without applying torque to the tool or workstring. A releaseable ratchet mechanism is also provided in the packer for trapping the setting loads when the packer is set in the casing. The ratchet mechanism is releasable by pulling up a housing portion which cammingly engages collapsible ratchet fingers thereby disengaging the ratchet finger trapping teeth from a stationary ratchet ring.

摘要： In accordance with an illustrative embodiment of the present invention, a circulating valve for use in sand control and related well operations includes a mandrel that can be rotated in a housing after a weight-responsive clutch is released. As the mandrel is rotated to the right, a reverse lead groove system engaged by a pawl causes a valve sleeve element to shuttle down and up between positions closing and opening a flow path between the annulus above a packer and a zone in the well below the packer.

摘要： A control valve apparatus adapted to be positioned within a subsea blowout preventer stack for controlling the flow of fluid from an offshore well includes a ball valve element provided with the capability of cutting coil tubing typically employed in well workover and completion operations. The ball element has a cutting edge that coacts with the valve seat to shear the tubing, and a relief slot that receives the tubing during cutting to prevent the tubing from being placed in double shear. Hydraulically operable means is provided to assist in closure of the ball valve element and consequent cutting of tubing extending into the well, in case of emergency.
