摘要： A latching system permits a firing head to be lowered into a wellbore and reliably coupled to a perforating gun previously lowered into the wellbore. In a disclosed embodiment thereof, the latching system includes a tubular collar associated with the firing head, and a stinger associated with the perforating gun. As the firing head approaches the previously lowered perforating gun, shearable studs projecting into the interior of the collar are received in external side surface J-slots formed on the stinger. The latching of the collar studs in the stinger J-slots permits the firing head/perforating gun connection to be verified simply by pulling up on and creating increased tension in the structure, such as a slick line, used to lower the firing head to the perforating gun. After the firing head is used to detonate the perforating gun, the spent firing head may be retrieved by pulling it uphole with sufficient force to shear its collar studs. Cooperating auxiliary attachment structures are formed on the firing head and perforating gun to facilitate their interconnection and simultaneous lowering into the wellbore if desired.

摘要： A system for use in a subterranean well includes a tubing, a perforating gun, a detonator and circuitry. The detonator is adapted to fire the perforating gun. The circuitry is adapted to determine whether the perforating gun has fired and based on the determination, operate a valve of the tubing to transmit a stimulus to the surface of the well to indicate whether the perforating gun has fired.

摘要： A safety system controls the activation of one or more downhole tools by providing selective transmission of an activation signal or an energy stream. In a preferred embodiment, transmission of the activation signal or the energy stream is allowed after the tool has passed below a known pre-determined depth. A preferred safety system includes a first device in fixed relationship with the downhole tool and a second device fixed at the stationary location. The first device permits, after reaching the pre-determined depth, either (a) an initiation signal to reach an initiation device associated with a downhole tool upon or (b) the energy stream to reach a downhole tool. The second device positively engages the first device to provide an indication that the specified depth has been reached.

摘要： A tool containing a solid combustible material is used to provide a pipe-cutting flame and to direct a pipe-cutting flame against a casing or tubular. The nozzles can be configured in any desired array and intensity. In the preferred embodiment, a rectangular window is burned away completely if the nozzles are sufficiently intense or the window is formed in segments if other distributions are used. The device can be anchored by a packer or anchor and can be run in the wellbore on tubing, wireline or electric line. The window can be produced in a single trip. The tool can be removed and a kick-off diverter installed adjacent the window for drilling the lateral.

摘要： A bi-directional explosive transfer subassembly (56) for coupling two explosive tools (52, 54) comprises first (74, 78) and second (76, 80) explosive carrying members that respectively define first (82, 86) and second (84) explosive cavities. A ball end (102) of the first explosive carrying member (74, 78) is slidingly received in a socket (114) of the second explosive carrying member (76, 80) such that the first (74, 78) and second (76, 80) explosive carrying members are rotatable and angularly displaceable relative to one another. A first explosive device (130) is disposed in the first explosive cavity (82, 86) and a second explosive device (132) is disposed in the second explosive cavity (84). The first (130) and second (132) explosive devices are spaced apart such that when one of the explosive devices (130, 132) is initiated, the other of the explosive devices (130, 132) will in turn be initiated.

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.
