Research at home and abroad of fluids loss agents in oil based drilling fluids are summarized. Fluid loss agents mainly include asphalt,humic acid,quebracho class,lignin,polymers,and introduces the research progress of the last four types of fluid loss agents. Humic acid is a kind of natural compound ma-terial commonly used to prepare fluid loss agents of oil-based fluids,polymeric loss agents have been de-veloped rapidly,showing excellent comprehensive performance. At last,it prospects the development direc-tion of fluid loss agents in oil-based drilling fluids.
