Review on the Development of Drilling Fluid Additives from Vegetable Phenols

Vegetable phenol compounds are renewable natural phenolic materials. Lignin and Tannin of them have been used as drilling fluid additives. Their modified products have been developed such as aqueous alkali of vegetable phenols, sulfonated vegetable phenols, complexed vegetable phenols with metal, oxidated vegetable phenols, condensed vegetable phenols, grafting copolymers of vegetable phenol with polymer, and so on. These products are mainly as the additives for dispersing drilling fluids. Their preparation methods and acting mechanisms in the drilling fluids are summarized in the paper. But now, there is a tendency to use non dispersing polymer drilling fluids. The drilling fluid additives above from plant phenols will be eliminated because they can not be used for non dispersing polymer drilling fluids. It is imperative to develop new vegetablephenol additives for non dispersing polymer drilling fluids. For this purpose, Thinners and filtration control additives should be developed which can modify the inhibitory proporty of polymer drilling fluids.
