    • Wellbore tools include a body and a superhydrophobic surface disposed over at least a portion of the body. The superhydrophobic surface includes a patterned surface of a hydrophobic material exhibiting a higher hydrophobicity than an unpatterned surface of the hydrophobic material. A wellbore tool may include a seal, at least one sensor, and at least one flow line, each having at least one superhydrophobic surface. Methods of forming wellbore tools include forming a body, forming a hydrophobic surface over at least a portion of the body, and forming a pattern in a surface of the body, such that the patterned surface exhibits a higher hydrophobicity than an unpatterned surface of the same material.
    • 井筒工具包括设置在身体的至少一部分上的主体和超疏水表面。 超疏水表面包括疏水材料的图案化表面,其表现出比疏水材料的未图案化表面更高的疏水性。 井眼工具可以包括密封件,至少一个传感器和至少一个流动管线,每个流动管线具有至少一个超疏水表面。 形成井筒工具的方法包括形成一个主体,在该主体的至少一部分上形成疏水表面,并且在该主体的表面上形成图案,使得该图案化表面的疏水性比该相同的未图案化表面显示出更高的疏水性 材料。
