摘要： A method of tertiary oil recovery from petroleum-containing formations at elevated temperature comprises injecting a substantiallyoxygen-free aqueous saline solution of water-soluble polysaccharide bipolymer treated at pH of at least 5 by the addition of an alkali metal salt of a reducing sulfur oxo acid selected from sulfurous acid and thiosulfuric acid as sole viscosity stabilizer.

摘要： The invention relates to a method of producing small spherical polymer particles from systems containing two liquid phases, the one phase of which contains one or more dissolved substances and is dispersed in the form of small droplets in the other phase to form an emulsion, whereafter the droplets are converted to a solid form. According to the invention the liquid phases used are two mutually immiscible aqueous phases.

摘要： An aqueous gel contains an organotitanate chelate as cross-linking agent, and a retarding agent which delays the crosslinking of the gel, the retarding agent comprising a polyhydroxyl-containing compound. The gel is useful for fracturing and placing propping agents within a subterranean formation. The gel developes a high viscosity (due to delayed crosslinking) when in the formation and has pumping characteristics in turbulent flow similar to those of water.

摘要： A gellable composition comprises (1) gellan, (2) xanthan gum, and (3) a galactomannan and/or glucomannan gum capable of producing a gel in combination with xanthan gum, especially carob, tara, cassia or konjac gum. Preferably the ratio of gellan: xanthan; gellan: galactomannan or glucomannan; and xanthan: galactomannan or glucomannan each lie within the range of from 5:1 to 1:5. In an aqeuous system the gum mixture is preferably present in a total amount of from 0.1 to 5% by weight based on the weight of the aqueous phase.

摘要： Blends of low-acetyl gellan gum with xanthan gum and a galactomannan gum, preferably locust bean gum, contain low-acetyl gellan: (xanthan/galactomannan) in the ratios by weight 95:5 to 5:95 in which the ratio xanthan: galactomannan ranges from 4:1 to 1:4. The combination of xanthan gum and locust bean gum modifies the brittleness of the gellan gum gel and provides a useful range and diversity of gel textures which find particular utility in gelled food formulations. In place of locust bean gum, konjak, tara, or Cassia gums may be used.

摘要： A gelling agent consisting essentially of a mixture of 30 - 90 wt. parts of xanthan gum and 10 - 70 wt. parts of konjakmannan is disclosed. The gelling agent is used in an aqueous solution having pH of 3.0 - 12.0. A quantity of the gelling agent is usually in a range of 0.2~4.2wt.% of the final product to be prepared. Any additive may be incorporated if necessary. Gel produced by utilizing the gelling agent has excellent hardness, elasticity, thermoreversibility and water-holding property.
