    摘要: The problem of fibre or particle settling in well cement slurries is addressed by providing a fluid containing two fibre components of differing properties. Such a well treatment fluid, comprising a base fluid; a first fibre component that it substantially more dense than the base fluid; and a second fibre component that has a density close to that of the base fluid and is relatively flexible.

    摘要: Fiber laden fluids may be used to separate two wellbore-service fluids as they travel through a tubular body, preventing their commingling. Such fluids obviate the need for mechanical devices such as wiper plugs, or special adjustment of the wellbore-service fluids' rheological properties. The wellbore-service fluids may be drilling fluids, spacer fluids, chemical washes, cement slurries, acidizing fluids, fracturing fluids, formation-consolidation fluids or gravel-pack fluids.

    摘要: Fiber bundles are prepared by affixing at least two fibers with a binding agent. The binding agent is designed such that the fiber bundles remain intact as the fiber bundles are mixed with and suspended in a fluid. After the fiber bundles exit the mixing apparatus, the binding agent degrades and releases the individual fibers. This allows higher concentrations of fibers to be added to fluids without fouling the mixing apparatus.

    摘要: Methods for servicing subterranean wells are disclosed. Particularly, the use of a fiber-laden fluid to separate and prevent the commingling of two stationary process fluids after placement in the borehole of a subterranean well, or in a tubular body installed in a subterranean well. The fiber-laden fluids prevent the cement plug from descending through drilling fluid to the bottom of the well. It obviates the need for mechanical devices such as packers, or special adjustment of the process fluids' rheological properties.
