摘要： An exploding foil bubble activated detonator, adapted for use in a perforating gun, includes an exploding foil, the exploding foil including as neck section which vaporizes when a current of sufficient magnitude and duration flows therethrough, a layer of polyimide material deposited over said foil, and a spacer layer deposited over said layer of polyimide material, the spacer layer including a guiding hole disposed directly over the neck section of the foil. When the current flows through the neck section of the foil, a turbulence is caused to occur directly above the neck section. This turbulence causes a portion of the polyimide material to expand to form a bubble. The bubble is shaped and sized by the guiding hole in the spacer layer which is disposed directly over the neck section of the foil. The shaped and sized bubble in the polyimide material impacts an explosive thereby detonating the explosive. A selective gun firing system may include the bubble activated detonator and functions to allow an operator to selectively fire, in a predetermined sequence, a plurality of perforators in the perforating gun, such as from bottom gun to top gun. A hall effect sensor disposed in a well truck is connected to a wireline to which the perforating gun is connected and senses a current in the wireline. A novel safety barrier is inserted into a hole in a barrel of a prior art exploding foil initiator (EFI) detonator for blocking a flying plate flying in the hole and thereby preventing accidental detonations of the EFI detonator.

摘要： A firing head adapted to connected between a coiled tubing and a perforating gun, is sized and shaped to enable it to move freely within a tubing string in the wellbore, may be actuated by fluid pressure within the coiled tubing, and includes a circulation and recirculation feature wherein wellbore fluid may be circulated through the firing head between the coiled tubing and an annulus around the tubing string, the circulation taking place either before or after detonation of the perforating gun. Three firing heads are discussed. One such firing head is a Circulation Direction Firing (CDF) Head. The CDF firing head circulates fluid from the wellbore to the coiled tubing and depresses a piston. Then, fluid pressure from the coiled tubing lifts the piston uncovering locking balls and propelling a firing pin to a booster of a detonating cord detonating the CDF firing head. Fluid circulation from the coiled tubing to the wellbore annulus begins after the CDF firing head detonates. Another such firing head is a Circulation Ball Firing (CBF) Head. The CBF firing head circulates fluid from the wellbore to the coiled tubing, receives a ball, and uses fluid pressure in the coiled tubing to lift a piston, uncover the locking balls and detonate the CBF firing head. Another such firing head is a Ball Actuated Circulation Firing (BCF) Head. The BCF firing head circulates fluid from the wellbore to the coiled tubing, receives a ball from the wellbore surface, and uses fluid pressure in the coiled tubing to push a piston downwardly which uncovers the locking balls and detonates the BCF firing head. Recirculation is permitted after the firing head detonates.

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 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 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.
