Abstract
(EN)
Provided are a substituted sugar or glycoside and the use thereof in a drilling fluid composition. The substituted sugar or glycoside carries a substituent A, a substituent B and a substituent C, wherein the substituent A comprises a group (I) in the structure thereof, the substituent B comprises a group (II) in the structure thereof, and the substituent C comprises a unit -NH-R7- in the structure thereof. The drilling fluid composition can show a better temperature resistance, fluid loss performance, contamination resistance, inhibition performance, lubricating performance or reservoir protection performance, and has no biological toxicity.
(FR)
La présente invention concerne un sucre ou un glycoside substitué et son utilisation dans une composition de liquide de forage. Le sucre ou le glycoside substitué porte un substituant A, un substituant B et un substituant C, le substituant A comprenant un groupe (I) dans sa structure, le substituant B comprend un groupe (II) dans sa structure, et le substituant C comprend un motif -NH-R7- dans sa structure. La composition de liquide de forage peut présenter une meilleure résistance à la température, une performance de perte de liquide, une résistance à la contamination, une performance à l’inhibition, une performance de lubrification ou une performance de protection de réservoir, et ne présente pas de toxicité biologique.
