    摘要: Vibrations are created in a flow conduit by constraining a bluff object having a plurality of positions between which flow of fluid forces the bluff object. In a preferred embodiment, the vibration technique is utilized in a gravel packing tool. Gravel pack sand is placed while the gravel pack tool is vibrated by balls constrained within a wash pipe. A considerably improved gravel pack density is achieved.

    摘要: A clamp is disclosed which is capable of latching on to a buckle arrestor on a subsea pipeline which has been severed in the vicinity of the buckle arrestor. By severing the pipe in this location and utilizing the buckle arrestor to latch the clamp on to the pipe, a simple and reliable clamp is used. A method to recover such a subsea pipeline by severing the pipeline in the vicinity of the buckle arrestor and utilizing such a clamp is also disclosed.

    摘要: A method and apparatus are provided for reducing the force required to move a pipe through a J-tube attached to an offshore platform. The J-tube is provided with at least two spaced-apart sections and at least the pipe and/or one section is oscillated as the pipe is moved through the J-tube, thereby reducing the force required to move the pipe.

    摘要: A wash down placement of a screen into sand within a well borehole is improved by vibration of a wash pipe as the wash pipe is removed from the screen. A compacted sand gravel pack around the screen is achieved. The vibrations are created by constraining a bluff object having a plurality of positions between which flow of fluid forces the bluff object.

    摘要: A reusable template is disclosed herein for use in cutting pipe and other related applications in conjunction as a guide for an oxygen cutting torch. The template, as described in a preferred embodiment as a pipe template, has one or more contour ends so configured that after the branch pipe is cut it will fit flush against the external surface of a header pipe at the desired angle determined by the configuration of the contour end. The template is made of oxidation resistant material, with an alloy content sufficient to produce refractory oxides when heated by a flame, thus preventing the template from being cut by the oxygen cutting torch. The template is held in place over or on the workpiece or pipe by means well known in the art. The contour end or shape of the template is used as a guide for the nozzle of a standard oxygen cutting torch. Since the template is made of oxidation resistant material, the torch will cut the workpiece or pipe in the configuration of the contour of the template without destroying the template.
