METHODS FOR PRODUCING EMULSIFIERS FOR OIL-BASED DRILLING FLUIDS

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 (I) 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 (II) 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 (II), and R3 is a C8-C20 alkyl, a C8-C20 alkenyl, a C8-C20 dialkenyl, or a C8-C20 alkynyl.
