A downhole fluid comprises a base fluid, for example a hydrocarbon base fluid, and a gelling agent. The gelling agent has an aromatic core of one or more aromatic rings, the gelling agent having two or more amide branches distributed about the aromatic core, each of the two or more amide branches having one or more organic groups. An example gelling agent is a pyromellitamide gelling agent. The pyromellitamide gelling agent may have the general formula of:
with R1, R2, R3, R4, R5, R6, R7, and R8 each being a hydrogen or an organic group. Methods of use and composition are discussed.
井下流体包括基础流体(例如碳氢基础流体)和胶凝剂。胶凝剂具有由一个或多个芳香环组成的芳香核心,胶凝剂具有两个或多个围绕芳香核心分布的酰胺分支,两个或多个酰胺分支中的每一个都具有一个或多个有机基团。吡喃甲酰胺胶凝剂就是一个例子。吡咯米特酰胺胶凝剂的通式为
R1、R2、R3、R4、R5、R6、R7 和 R8 各为氢或有机基团。讨论了使用方法和组成。
