Abstract: The use of gelatin-based copolymers containing at least one grafted side chain formed from ethylenically unsaturated compounds as an anti-accretion additive is proposed for water-based drilling fluids in the development, exploitation and completion of underground mineral oil and natural gas deposits and in deep wells. These copolymers are water-soluble and have good biodegradability.

Abstract: El uso de copolímeros a base de gelatina que contienen por lo menos una cadena lateral injertada formada de compuestos etilénicamente insaturados como un aditivo anti-acreción se propone para fluidos de perforación a base de agua en el desarrollo, explotación y completación de depósitos de aceite mineral y gas natural subterráneos y en pozos profundos. Estos copolímeros son solubles en agua y tienen buena biodegradabilidad.
