Oil well drilling fluids, oil well drilling fluid anti-settling and method of providing anti-setting properties to oil well drilling fluids |
摘要 |
An improved drilling fluid with enhanced anti-settling properties useful for all types of drilling systems is described. The invention includes a process for providing anti-settling properties to both oil and invert oil (i.e., water in oil emulsion) based fluids as well as the additive itself. The drilling fluid drilling mud invention contains at least one reaction product of which the reactants comprise an alkoxylated aliphatic amino compound and an organic polycarboxylic anhydride or acid and a rheologically active clay-based material.
