摘要： A device for connection to a wellhead for coupling a drive assembly for a downhole pump with an apparatus having a rotatable member for driving the apparatus. A rotatable first shaft, having a first end and a longitudinal axis, is associated with the drive assembly such that the first shaft is rotated thereby. A rotatable connector, having driven and drive ends, connects the first shaft with the rotatable member such that rotation of the first shaft rotates the connector. The driven end connects with the first end of the first shaft. The drive end connects with the rotatable member. A rotatable coupler, having driven and drive ends and a longitudinal axis, connects the first shaft with the connector. The driven end of the coupler connects with the first end of the first shaft. The drive end of the coupler connects with the driven end of the connector. The longitudinal axis of the first shaft is substantially coaxial with the longitudinal axis of the coupler such that the driven end of the connector rotates substantially coaxially with the first shaft.

摘要： A tubing head is provided for accommodating a rotator. The rotator includes a drive gear and a swivel tubing hanger which engages an internal surface of the tubing head and comprises a driven gear for engaging the drive gear. The tubing head defines a gear housing for the drive gear so that the drive gear may releasably engage the driven gear. The internal surface, gear housing and drive and driven gears are configured such that when the drive gear is in the gear housing, the tubing hanger engages the internal surface and the drive and driven gears are engaged, the tubing hanger may be removed from the tubing head by pulling it through the upper end without first disengaging the drive and driven gears. An apparatus is also provided comprising the tubing head, the swivel tubing hanger and the drive gear.

摘要： A tubing rotator and hanger that attaches to a wellhead for suspending and rotating a tubing string contained in a wellbore. The tubing hanger comprises a support flange which mounts on the wellhead flange. The tubing rotator comprises a tubular outer member which engages the support flange, a tubular inner mandrel which is connected to the tubing string which is rotationally supported within the outer member, apparatus for rotating the inner mandrel which engage the inner mandrel at its upper end, and a housing mounted around the upper end of the inner mandrel for supporting the portion of the wellhead located above the tubing rotator. The rotating apparatus may be disengaged from this inner mandrel and the housing is removable so that a blowout preventer may be placed on top of the support flange and over the outer member and the inner mandrel and mounted on the wellhead without first moving the tubing string, and so that the outer member, the inner mandrel and the tubing string may be pulled through the blowout preventer to service the well. An adaptor is provided so that the rotating apparatus may be driven automatically by a rotating polished rod. The adaptor comprises a sleeve that fixedly mounts on the rotating rod, a shaft which engages the sleeve in order to be rotated as the sleeve rotates, and an adaptor housing for supporting the first shaft mounted about the sleeve so that the sleeve may rotate within the adaptor housing. The first shaft is connected to the rotating apparatus by a flexible second shaft, and the rotating apparatus includes a gearbox which creates a mechanical advantage so that rotation of the rotating rod rotates the inner mandrel and the tubing string.

摘要： A method and an apparatus for connection with a tubing string for use in a wellbore for regulating the flow of a fluid within a wellbore annulus between the tubing string and the wellbore. The apparatus includes a tubing rotator and at least one packer valve for connection with the tubing string, wherein the packer valve is actuatable through rotation of the tubing string by the tubing rotator. Rotation of the tubing string actuates the packer valve between a closed flow position wherein the packer valve substantially seals the wellbore annulus and an open flow position wherein the flow of the fluid is permitted through the wellbore annulus. The method includes the steps of suspending the tubing string in the wellbore by the tubing rotator, connecting the packer valve with the tubing string and rotating the tubing string by the tubing rotator in the first direction to actuate the packer valve to the closed flow position.

摘要： A process and apparatus for treating a crude oil containing water. An inlet introduces a flow of the crude oil into the apparatus, wherein at least a portion of the water is a vapor. A first separator disrupts the crude oil flow in order to separate at least a portion of the vapor from the crude oil to produce a treated oil. A heater heats the treated oil to produce a heated treated oil. Means for recycling a first amount of the heated treated oil from the heater to the inlet are provided. The first amount is at least sufficient to heat the crude oil to a temperature such that at least a portion of the water forms the vapor. At least one oil outlet removes the treated oil and at least one vapor outlet removes the vapor. Finally, means are provided for producing the flow of the crude oil. The process is preferably conducted using the apparatus.

摘要： The invention relates to a method and a device for longitudinally adjusting the position of a rotating rod string, having an upper end and a lower end, in a production well of the type having a downhole rotary pump connected to the lower end of the rod string, means for driving the rotary pump by rotating the rod string, and a lower clamp operably connected to the driving means and releasably fixable near the upper end of the rod string such that operation of the driving means rotates the lower clamp which rotates the rod string. The device is comprised of a tubular inner sleeve having a threaded outer surface and a lower end for removably mounting on the lower clamp such that the rod string is contained therein and rotation of the lower clamp by the driving means rotates the inner sleeve. A tubular outer sleeve having an upper end and a threaded inner surface is mounted about and threadably engaged with the inner sleeve. An upper clamp is mounted on the upper end of the outer sleeve and is releasably fixable to the rod string so that while the lower clamp is released from the rod string and the upper clamp is fixed to the rod string, operation of the driving means rotates the lower clamp and the inner sleeve such that the outer sleeve telescopes relative to the inner sleeve until the rod string is longitudinally adjusted within the well by longitudinal movement of the upper clamp.
