    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 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: The present invention relates to a subsea pipeline and method utilizing the pipeline wherein the loss of pipeline contents resulting from a break in the pipeline is reduced. The loss of pipeline contents is reduced by providing a plurality of traps in the pipeline. The traps each comprise at least two elevation changes in alternating directions. Any water entering the pipeline through a breach will only displace pipeline contents from the breach to the adjacent lower trap.

    摘要: A device having a large fluid drag tendency is lowered into a well at a rate which gives no net drag against the fluid. The condition of no net drag is indicated by the tension in a line used to lower the tool into the well. When the spool-off rate is such that this tension force is equal to or slightly exceeds the weight of the tool plus the weight of the line in the borehole the tool is moving at a speed equal to the average flow velocity in the well. This velocity may be determined by measurement of the spool-off rate.

    摘要: A method and apparatus for determining the vapor flow only, or the vapor and liquid flows into various formations surrounding a thermal injection well. The apparatus utilizes a downhole tool having bristles on its outer surface for impeding the flow of fluid past the tool and an instrument at the surface for measuring the drag force produced on the tool as it is moved downward and upward through the well. The fluid flows at various depths in the well are calculated from the measured drag forces.

    摘要: A method and apparatus for venting purge fluid from an enclosed housing to maintain a positive known reference pressure differential between the housing and the variable pressure atmosphere surrounding the housing. The apparatus utilizes a specially designed fluidized bed to vent the purge fluid while maintaining a positive known reference back pressure. The fluidized bed automatically compensates for changes in the temperature or pressure of the atmosphere surrounding the housing.
