摘要： Solid proppants are coated with a coating that exhibits the handling characteristics of a precured coating while also exhibiting the ability to form particle-to-particle bonds at the elevated temperatures and pressures within a wellbore. The coating includes a substantially homogeneous mixture of (i) at least one isocyanate component having at least 2 isocyanate groups, and (ii) a curing agent. The coating process can be performed with short cycle times, e.g., less than about 4 minutes, and still produce a dry, free-flowing, coated proppant that exhibits low dust characteristics during pneumatic handling but also proppant consolidation downhole for reduced washout and good conductivity.
摘要翻译：固体支撑剂涂覆有表现出预固化涂层的处理特性的涂层，同时还显示出在井筒内的升高的温度和压力下形成颗粒 - 颗粒粘合的能力。涂层包括（i）至少一种具有至少2个异氰酸酯基的异氰酸酯组分和（ii）固化剂的基本上均匀的混合物。涂覆过程可以以较短的循环时间（例如小于约4分钟）进行，并且仍然产生干燥，自由流动的涂覆的支撑剂，其在气动处理期间表现出低灰尘特性，而且还支撑剂固结在井下以减少冲洗和良好的导电性。

摘要： Solid proppants are coated with a phenol-urethane coating in one or more layers by a method comprising coating a proppant solid and then curing the coated proppant under conditions sufficient to substantially cure said proppant, wherein said coating comprises a substantially homogeneous mixture of (i) an isocyanate component having at least 2 isocyanate groups, (ii) an amine reactant, and optionally (iii) an amine that is a latent curing agent for said isocyanate.
摘要翻译：固体支撑剂通过包括涂覆支撑剂固体然后在足以基本上固化所述支撑剂的条件下固化所述涂覆的支撑剂的方法在一层或多层中涂覆苯酚 - 氨基甲酸酯涂层，其中所述涂层包含（i）具有至少2个异氰酸酯基团的异氰酸酯组分，（ii）胺反应物，和任选地（iii）作为所述异氰酸酯的潜在性固化剂的胺。
