    摘要： Methods of forming one or more plugs in a well bore are provided. The methods basically comprise the steps of dropping into the well bore a cementitious material which will delayedly react with water therein to form an impermeable solid and which has been formed into agglomerates of sufficient weight to sink through the water and other fluids and materials in the well bore. The agglomerates are dropped in a quantity sufficient to form a mass of the agglomerates in the well bore. Thereafter, the mass of agglomerates is allowed to react with the water in the well bore and set into an impermeable solid plug therein.

    摘要： Powder mixtures and a method of forming and shaping the mixtures. The method involves compounding the components of powder materials, binder, solvent for the binder, surfactant, and non-solvent with respect to at least the binder, the solvent, and the powder materials. The non-solvent is lower in viscosity than the binder combined with the solvent. The solvent is present in an amount that is less than the amount that would be present otherwise. The components are mixed and plasticized, and shaped to form a green body. The choice of components results in improved wet green strength in the green body. The method is especially useful for extrusion processing of aqueous binder systems such as water and cellulose ethers and hydrophobic non-solvents, to form structures such as honeycombs. In the body, the ratio, upon subsequent firing, of the isostatic strength to the A-axis strength is at least about 20% higher than in bodies made without the mixture composition of the invention. A honeycomb body having a ratio of the isostatic strength to the A-axis strength of at least about 0.33 upon firing.
