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

摘要： Mixtures of fibers and solid particles are effective for curing fluid losses and lost circulation in a subterranean well. Stiff fibers are more effective than flexible ones; however, mixtures of stiff and flexible fibers have a synergistic effect. The quantity and particle-size distribution of the solids are optimized according to the stiffness, dimensions and concentrations of fibers.

摘要： The present invention relates to a method of accelerating the compressive strength development and setting time of a cement slurry during a cementing operation for a wellbore. The method generally comprises the steps of preparing a cement slurry comprising a hydraulic cement and water at the surface; placing the cement slurry in the wellbore; adding an activator to the cement slurry in the wellbore; and allowing the cement composition to set, wherein the activator acts as a set accelerating agent and a compressive strength enhancing additive.

摘要： A cement slurry composition for cementing a well comprising: a hydraulic cement, water and a combination made of a hydroxyethyl cellulose and an acrylamido-methyl-propane sulfonate-acrylamide copolymer. Provided is also a method for cementing a well involving such cement slurry composition. The composition provides a solution to decouple the fluid-loss control and the slurry rheologyfor cement for slurry and particularly for extended cement slurry.
