Organophilic polyphenolic acid adducts |
摘要 |
Organophilic polyphenolic materials which are effective fluid loss control additives for oil base well-working fluids are prepared from a polyphenolic material and one or more phosphatides. Preferred phosphatides are phosphoglycerides obtained from vegetable oils, most preferably commercial lecithin. Preferred polyphenolic materials comprise one or more of: humic acid; lignosulfonic acid; lignins; phenolic condensates; tannins; the oxidized, sulfonated, or sulfomethylated derivatives of these polyphenolic materials; and the water soluble or colloidally dispersible salts of these polyphenolic materials or these derivatives thereof.
