N-hydroxyalkylated polyamines, methods of making N-hydroxyalkylated polyamines, and drilling fluids containing N-hydroxyalkylated polyamines are provided, in which the N-hydroxyalkylated polyamine includes Formula (I):
where R1 and R2 are independently a —C or —CH group; R3 is an aliphatic hydrocarbyl; R4 and R5 are independently acyclic hydrocarbyls, or R1, R2, R4, and R5 are covalently connected to form a cyclic hydrocarbyl; and R6, R7, R8, and R9 are independently acyclic hydrocarbyls or acyclic heterohydrocarbyls.
提供了 N-羟基烷基化多胺、制造 N-羟基烷基化多胺的方法以及含有 N-羟基烷基化多胺的钻井液,其中 N-羟基烷基化多胺包括式 (I):
其中 R1 和 R2 独立为-C 或-CH 基团;R3 为脂肪族烃基;R4 和 R5 独立为非环烃基,或 R1、R2、R4 和 R5 共价连接形成环烃基;以及 R6、R7、R8 和 R9 独立为非环烃基或非环杂烃基。
