摘要： Substituted scleroglucans are produced and are used in the producing drilling fluid compositions. Each of the substituted scleroglucans and combination thereof have substituent A, substituent B and substituent C, and optionally each or in combination have substituent D and substituent E. Substituent A contains in its structure a unit —C(═O)—O—, substituent B contains a unit —C(═O)—NH—, substituent C contains a unit

substituent D contains an aryl group, and substituent E contains a siloxane group. The substituted scleroglucan shows tackifying performance under high temperature conditions and a reduced filtration loss.

摘要： An aryl-substituted saccharide or glycoside or a mixture of a plurality of aryl-substituted saccharides or glycosides have at least good resistance to high temperatures and salt, and lower filtration loss. These aryl-substituted saccharide or glycoside are used in making a drilling fluid composition. The aryl-substituted saccharide or glycoside or the mixture of a plurality of aryl-substituted saccharides or glycosides each or in combination bears a substituent A and a substituent B, wherein the substituent A contains a unit —O—R6— in its structure and the substituent B contains a unit in its structure, and the substituents and the numbers are defined in the description.
