The utilization of alkali lignin, a by product of pulping industry, is the need for the environmental protection. Lignin based oilfield chemicals have the benefit of cheapness and can be used for different purposes. In this paper the complicity in chemical structure, the properties (dispersive, binding, surface activity), and the principal methods of modification of alkalin lignin are introduced. The lignin based chemicals used and recommended as treating agents for drilling fluids, cement additives, water plugging profile controlling agents, EOR surfactants (sacrificial agents and flooding chemicals) and the direct use of black liquor as flooding fluid are reviewed. At present time in China the alkali lignin from non wood black liquor is the main raw material to prepare oilfield chemicals.
