摘要

Summary "materials of oil field oil absorbents and additives in applications of drilling fluid base oil that is a method that uses a single additive to modify or enhance one or more properties of a drilling fluid to drill a hole of P. Ou00e7o in an underground formation.To avoid the loss of movement during drilling and / or increase the bond strength during the cementing of well bore. The additive comprises an absorbent material for oil comprising homopolymers or copolymers comprise styrene, butadiene, acrylic acid, phthalate, and salts of carb Onato.
