摘要： An apparatus and method for cementing a casing string in a wellbore. A self-filling tubular cementing collar connected to the lower end of a casing string is provided with one-way flow valving that allows well fluid to enter and self-fill the casing string as it is lowered into the wellbore and automatically prohibits reverse fluid flow from the collar when washing or cementing during forward circulation through the collar. The one-way valving is carried by an axially movable support that can be shifted by a cementing plug moved by pump pressure to permanently seal the entry flow passage after the casing sting is properly positioned in the wellbore.

摘要： A short stroke casing valve with positioning and jetting tools therefor. The casing valve has a sliding sleeve within a housing. The housing defines a housing communication port therethrough, and a seal is disposed on longitudinally opposite sides of the housing communication port. The sleeve has a selective latch profile therein adapted for engagement by the positioning tool. The positioning tool has outwardly biased positioner blocks which automatically engage the sliding sleeve. The positioner blocks have a selective latch profile thereon which is adapted for engagement with the latch profile in the sliding sleeve. This latch profile in the positioner tool prevents undesirable engagement of the positioner blocks with any other portion of the casing string except the latch profile in the casing valve. In one embodiment, a non-rotational jetting tool includes a plurality of circumferentially spaced jetting orifices therein. There is a sufficient number of orifices so that at least one of the orifices is substantially radially aligned with the housing communication port when longitudinally aligned therewith, so that jetting through the housing communication port may be accomplished without rotation of the tool string. A jetting tool having rotational jetting is also disclosed.

摘要： A seal for long-time exposures in oil and gas well tools. The seal is adapted for use in a sealed joint between two relatively movable members. In particular, the seal is designed for relatively slidable members. The seal has a body portion with a pair of annular arms extending from opposite sides thereof. A lip on each of the arms is adapted for engaging one of the relatively movable members. An elastomeric sealing element may be disposed in a groove in the body portion for dynamic sealing between the first and second members. Pusher rings may be disposed on opposite sides of the seal so that the seal may be clamped against one of the relatively movable members without the lips or arms longitudinally engaging either of the relatively movable members or a lock ring used to clamp the seal in place.

摘要： A casing cementer with torque-limiting rotating positioning tool. The casing cementer comprises a housing with a rotating valve sleeve therein. A positioning tool is used to rotated the valve sleeve between open and closed positions thereof. No reciprication of the positioning tool is required. The valve sleeve has a sealing ring molded thereto for sealing between the housing and the valve sleeve. The valve sleeve preferably has an inside diameter at least as large as an inside diameter of the casing. A stop is provided to limit movement of the valve sleeve when it reaches either the open or closed position. A clutch in the positioning tool provides for torque-limitation and a ratcheting indication to the operator at the surface when the valve sleeve has been opened or closed.

摘要： A cement head and casing assembly includes a cement head body having a cement passage defined therethrough. The body is mounted on the well casing and has a lower portion extending down into the casing, with an upper portion extending a relatively short distance above an upper end of the casing. A cement plug is closely received within a bore of the casing below the upper end thereof. The cement plug is releasably connected to the lower portion of the cement head body so that the plug is suspended from the lower portion of the cement head body within the casing. The cement plug has a plug passage defined therethrough which is communicated with a cement passage in the cement head body so that cement can be pumped down through the cement head body and the cement plug into the casing. The passage through the cement plug can be closed and the cement plug can be released from the cement plug body after the cement has been pumped into the casing.

摘要： A method of gravel packing multiple zones with a single trip of the operating string into a well without inducing fluid movement across zones, and without disturbing the zone being packed in reverse circulation. Apparatus is disclosed to perform the method, comprising a screen liner assembly surrounding a concentric operating string. Mechanical force on the operating string is used to change all tool modes of the apparatus. The operating string is accurately positioned with respect to the screen liner assembly at every zone level and zones may be easily relocated if necessary. Zones may be packed in any order, and a zone may be repacked, if necessary, during the same trip into the well.
