摘要： A downhole device and method for performing a function in a well. The device has a series of dedicated hydro-mechanical locks that prevent occurrence of an associated function. The hydro-mechanical locks are capable of being released directly by a respective elevated hydraulic activating pressure condition, and are constructed and arranged for sequential operation, such that a successive lock in the series cannot be released until after the hydraulic pressure condition required to release the preceding lock in the series has occurred. In a preferred embodiment, an actuator sequentially releases each lock in a series of locks, subsequently moving an operator to perform a function. A preferred implementation employs a series of resilient rings movable, sequentially, from a locking to an unlocking position, and a common actuator that effects these movements. Multiple devices of this construction are advantageously arranged in a string of tools to perform functions in any preprogrammed order by pre-selecting the number of locks in each device. In one embodiment, movement of the operator arms an associated ballistic tool downhole. Methods of performing sequences of downhole well functions are also disclosed.

摘要： A shock absorber, adapted to be disposed above a perforating gun in a tool string and adapted to be disposed in a wellbore, includes a crushable element disposed between an inner and outer housing, a frangible breakup element, and a detonating cord disposed within the frangible breakup element and connected to the perforating gun. In operation, a detonation wave propagates within the detonating cord on its way toward the perforating gun. However, before the detonation wave reaches the perforating gun, the detonation wave propagates through the frangible breakup element. In response to the passage of the detonation wave through the frangible breakup element, the frangible element shatters into a multitude of pieces. Before the frangible element shatters, the frangible element absolutely prevents any shock from being absorbed by the shock absorber of the present invention. As a result, preloading effects are avoided. However, after the frangible element shatters, the shock absorber of the present invention is ready to absorb the shock resultant from the detonation of the perforating gun. After the frangible element shatters, in response to the detonation wave passing therethrough, the inner and outer housings move in opposite directions relative to one another in response to a received shock and the crushable element begins to permanently deform. An upward or a downward shock may be absorbed by the shock absorber, but only after the frangible breakup element shatters in response to the detonation wave in a detonating cord passing therethrough.

摘要： A production valve includes an outer housing having a production port, a piston disposed within the outer housing and adapted to move from one position to another position, a frangible breakup element supporting the piston in the one position, and a detonating cord adapted for propagating a detonation wave passing through the center of the piston and the breakup element. The detonation wave shatters the frangible breakup element when the detonation wave, propagating within the detonating cord, passes through the breakup element. When the breakup element shatters, the support provided to the piston by the breakup element is removed. When the support provided to the piston by the breakup element is removed, the piston moves from the one position to the other position in response to either tubing pressure or rathole pressure or both, and the production port of the production valve opens when the piston moves to the other position.

摘要： A circulation valve is disclosed for use in a tubing-conveyed tool string. The valve is adapted to be open as the tool string is run into the well, enabling circulation flow from the tubing into the well bore. To close the valve, the circulation flow rate is increased. The valve has a housing with an inner bore and defining both a passage in hydraulic communication with the tubing and a side port for hydraulic communication between the passage and the well. A piston disposed within the inner bore of the housing is adapted to be moved along the inner bore of the housing by elevated tubing pressure to block the side port of the housing. A set of shear pins retain the piston in its initial position until broken by the elevated tubing pressure. The piston defines a side port for hydraulic communication between the passage and the side port of the housing with the piston in its initial position, the size of the side port being selected to cause a sufficient pressure buildup within the tubing at a predetermined flow rate to shear the pins and move the piston. Some embodiments have an air chamber between the piston and housing. Methods of use are also disclosed.

摘要： A shut-off valve is disclosed for use in a downhole string of tools in a well. The valve has a housing adapted to be connected between adjacent tools of the string, defining a bore and a passage for hydraulic communication between the adjacent tools. The passage is arranged to intersect the bore, and a piston is slidably disposed within the bore and arranged to block hydraulic communication between the passage and the piston bore. The piston is further arranged to, in a first position, permit hydraulic communication along the passage, and to, in a second position, block hydraulic communication along the passage. The piston also has a bore for ballistic communication between the adjacent tools, such that it can be employed between a firing head and a gun, for instance. Some embodiments also permit circulation flow from the tubing to the well bore after the valve has closed. Methods of use and tool strings containing such valves are also disclosed.

摘要： A completions insertion and retrieval under pressure (CIRP) apparatus utilizes a snaplock connector to assemble uphole a tool string of any desired length prior to lowering the tool string into a wellbore for performing wellbore operations in the wellbore. The tool string could comprise a perforating gun string including a plurality of perforating guns interleaved with a corresponding plurality of snaplock connectors. The CIRP apparatus includes a winch housing connected to a lubricator, the lubricator being connected to a valve, the valve being connected to a connection apparatus, such as a deployment BOP or a snaplock operator, the connection apparatus being connected to a work string which extends into the wellbore. When the valve is opened and the lubricator is pressurized, a second wellbore tool, which includes a third section of a snaplock connector, is disposed in the lubricator and a first wellbore tool, which includes a first and second section of a snaplock connector, is being held by the connection apparatus. The second wellbore tool is lowered by the winch through the lubricator into contact with the first wellbore tool, and the third section is connected to the second section of the snaplock connector. The connection apparatus releases its hold on the first wellbore apparatus, the winch lowers the second wellbore apparatus into the connection apparatus, and the connection apparatus holds the second wellbore apparatus until a third wellbore apparatus is connected to the second wellbore apparatus thereby creating a tool string. As a result, the tool string of any desired length can be build uphole before lowering the the tool string downhole for performing wellbore operations during one trip into the wellbore.

摘要： A hydraulic safety pin is interconnected between a device, such as a pressure controlled firing head associated with a perforating gun, and a small diameter tubing in a wellbore. When, the small diameter tubing is filled with fluid under pressure, the hydraulic safety pin allows the fluid to fill the small diameter tubing but prevents the pressure of the fluid in the small diameter tubing from accidentally detonating the firing head when the pin is disposed in a first position; however, when the tubing is already filled with fluid under pressure, the hydraulic safety pin allows the pressure of the fluid in the small diameter tubing to detonate the firing head when the pin is disposed in a second position. The hydraulic safety pin may be installed in a special coupling, and multiple special couplings may be used in a tool string disposed in a wellbore.

摘要： A perforating gun having no firing head and no primary explosives is attached to a tubing string and the tubing string is run into a borehole. A new pump apparatus, having a firing head, is run into the tubing string until the pump firing head is adjacent the perforating gun. The firing head in the pump apparatus detonates, firing the perforating gun. If the firing head fails to detonate, one need only remove the pump apparatus from the tubing string in order to gain access to the firing head, for repair and replacement thereof. One need not remove the tubing string to gain access to the firing head.
