Study on the Effect of Humic Acid Acetamide on the Rheological Properties of Diesel Oil-Based Drilling Fluids

Abstract:

A new kind of humic acid acetamide compoud was synthesized by chemical modification of humic acid with octadecylamine, and the effect of humic acid acetamide on the rheological properties of oil-based drilling fluids was investigated. The results indicated that the humic acid acetamide had excellent dispersing property, and good capacity of depressing fluid loss. Moreover, the humic acid acetamide had better property of depressing fluid loss than oxidated asphalt. As a result, this humic acid acetamide is an excellent fluid loss agent for diesel oil-based drilling fluids, and is an good alternative to oxidated asphalt.
