摘要： A petroleum well (20) for producing petroleum products that incorporates a system adapted to controllably route communications and/or electrical power having a time-varying current through a piping structure (30 and/or 40) in the well (20), and methods of producing petroleum products use such a well, are provided by the present invention. The system comprises a first induction choke (70 or 100), a second induction choke (70 or 100), and a controllable switch (90). The first induction choke (70 or 100) is located about a portion of a first branch (26) of the piping structure (30 and/or 40). The second induction choke (70 or 100) is located about a portion of a second branch (29) of the piping structure (30 and/or 40). The controllable switch (90) comprises two switch terminals. A first of the switch terminals is electrically connected to the piping structure (30 and/or 40) on a junction side (81) of the induction chokes (70 or 100). The first and second branches (26 and 29) of the piping structure (30 and/or 40) intersect on the junction side (81) of the induction chokes (70 or 100). A second of the switch terminals is electrically connected to the piping structure (30 and/or 40) on another side (82) of at least one of the induction chokes (70 or 100).

摘要： A current impedance device in the form of a ferromagnetic choke in a petroleum well where a voltage potential is developed across the choke to power and communicate with devices and sensors in the well. The petroleum well includes a cased wellbore having a tubing string positioned within and longitudinally extending within the casing. A controllable gas lift valve, sensor, or other device is coupled to the tubing. The valve sensor, or other device is powered and controlled from the surface. Communication signals and power are sent from the surface using the tubing, casing, or liner as the conductor with an earth ground. For example, AC current is directed down a casing to a lateral where the current encounters a choke. The casing is generally electrically isolated from earth by the cement, while the lateral terminates at an earthen ground.

摘要： A pack-off system for packing off an area of interest in a wellbore, the pack-off system comprising a body, two spaced-apart selectively settable packing elements on the body for sealing off the area of interest, selectively actuatable setting apparatus connected to the body for selectively setting the two spaced-apart selectively settable packing elements, the selectively actuatable setting apparatus actuatable by fluid under pressure introduced into the pack-off system. The system includes a release apparatus actuatable by pressure reduction. A method for packing off an area of interest in a wellbore, the method including installing a pack-off system as described herein in the wellbore to pack-off the area of interest. Such a method may also include flowing treatment fluid from the pack-off system to an area of interest in an earth formation and/or adjacent a wellbore in the earth.

摘要： A safety valve for use in a wellbore formed in an earth formation, comprising a valve body (6) having a fluid passage for passage of a stream of hydrocarbon fluid flowing from the earth formation via the wellbore to the earth surface, a closure member (18) movable relative to the valve body between an open position in which the fluid passage (12) is open and a closed position in which the closure member closes the fluid passage, and an activating device (30) for selectively subjecting the closure member (18) to a drag force of selected magnitude, the drag force being exerted by the stream of fluid and inducing the closure member to move from the open position to the closed position thereof. The safety valve further comprises control means (46) for controlling the activating device to subject the closure member to said drag force.

摘要： When drilling deep boreholes with a down-the-hole drill (15), the pressure and the flow of the motive fluid are controlled so that the impact velocity of the piston hammer of the drill is kept within narrow limits independently of the counter pressure in the borehole. For this purpose the quotient of pressure and flow can be held substantially constant.
