摘要： A downhole valve for use within a string of tools in a well for controlling a hydraulic activation circuit. The valve has a housing with an inlet and an outlet, defining a portion of the circuit extending between the inlet and the outlet. A moveable piston within the housing in a first position provides communication between uphole and downhole parts of the circuit, and in a second position isolates the uphole and downhole parts of the circuit. A frangible member is constructed to support, in an intact condition, the piston in one of these two positions against a biasing force, and in a shattered condition enables the piston to move in response to the biasing force to the other position. A detonating member extending through the frangible member propagates a detonation wave to shatter the frangible member when desired, closing the valve. The valve is capable of closing very rapidly, and is particularly useful for isolating an uphole part of a hydraulic activation circuit when used with detonatable tools that can damage hydraulic control lines upon detonation, such as perforating guns. In other embodiments the valve is used to enable hydraulic activation of a tool when opened by a detonation. Methods of altering a hydraulic activation circuit within a string of tools in a well are also disclosed.

摘要： A tool for performing a downhole function in a horizontal or highly deviated well has a downhole structure with a longitudinal axis and constructed to turn about the axis in response to a moment applied about the axis. The structure includes at least one ballast chamber containing a flowable inert ballast material, such that the gravitational center of the material-containing chamber is effectively offset from the longitudinal axis of the structure to enable the chamber to contribute to gravitational orientation of the tool within the well to a desired position. In another configuration, the structure is rotatable within a housing and supported by bearings. The chamber is preferably filled with tungsten or depleted uranium powder for maximum density. A swivel for use with the tool, capable of passing both hydraulic pressure and detonation waves, decreases the overall length of the rotating part of the tool string. The method of using an offset ballast to desirably orient a tool in a horizontal or highly deviated well is also disclosed.

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. Methods of performing sequences of downhole well functions are also disclosed.

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.

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 tool for initiating a downhole function in a subsurface well, such as a cased well. The tool has memory adapted to store a well-specific reference pattern of one or more downhole well characteristics as a function of position along the well, one or more sensors responsive to the downhole well characteristics, and a clocked processor. The processor is adapted to receive well characteristic signals from the sensors, determine, from the signals and the reference pattern in memory, the position of the tool along the well, and automatically initiate a downhole function at a preprogrammed position along the well while the tool is moved at a substantially constant rate along the well. The tool may be configured in a string of tools for performing multiple downhole functions. In some embodiments the reference pattern is the known spacing of discrete downhole features, such as casing collars. In some other embodiments the reference pattern is a log of a geophysical parameter, such as a natural gamma log. Methods of use are also disclosed.

摘要： A downhole valve is disclosed for use in a tubing-conveyed string of tools in a well bore, constructed to be actuated to open under pressure forces by dropping a drop bar from the well surface through the tubing. The valve, deployed in the well in a closed condition, has a frangible member arranged to be broken by the drop bar to enable the valve to open. The valve opens under well pressure forces when well pressure exceeds tubing pressure, and opens under tubing pressure forces when tubing pressure exceeds or substantially equals well pressure. The valve is particularly useful when opened in conjunction with the detonation of a perforating gun for overbalanced or underbalanced well perforation. Methods of operating a string of tools including the valve are also disclosed.

摘要： A shock absorber is adapted to be disposed within a perforating gun string or within the tubing string above the perforating gun and includes an energy absorbing element adapted to absorb and store mechanical energy during detonation of the perforating gun and to permanently deform in response to the storage of the mechanical energy, the stored energy being released in the form of heat, and not in the form of kinetic energy. Therefore, following absorption of the mechanical energy by the shock absorber, no further expansion of the shock absorber is experienced. The shock absorber includes an inner housing, an outer hosuing, a connection for interconnecting the inner and outer housing, and a break up charge for breaking the connection and releasing the inner housing from the outer housing when the perforating gun is detonated whereby the shock absorber is as strong as the tubing string before the connection is broken and is flexible after the connection is broken. The energy absorbing element may be a damping coil or it may be a honeycomb. The damping coil and honeycomb energy absorbing elements permanently deform when mechanical energy is absorbed; therefore, the stored mechanical energy is subsequently released in the form of heat and not in the form of kinetic energy.
