摘要:
Methods for making emulsifiers, emulsified drilling fluids, and methods for using the same are provided. In one or more embodiments, the method for making an emulsifier can include mixing a tall oil and a triamide. The triamide can have the chemical formula: where: x, y, and z are integers independently selected from 1 to 10, R1 is a C8-C20 alkyl, a C8-C20 alkenyl, a C8-C20 dialkenyl, or a C8-C20 alkynyl, R2 is H or independently selected for each [(CH2)xNR2(CH2)y] unit, where R4 is a C1-C3 alkylene or a C1-C3 alkylene alcohol, and where at least one R2 is and R3 is a C8-C20 alkyl, a C8-C20 alkenyl, a C8-C20 dialkenyl, or a C8-C20 alkynyl.
