    • A method is for consolidating particulate matter in a well. The method comprises injecting a composition into a sand bearing formation. The composition comprises a curable non-aqueous, homogeneous liquid, an initiator for heat induced production of free radicals, a pot life extending inhibitor for stabilization of free radicals, and optionally an accelerator and optionally a filler. The non-aqueous, homogeneous liquid further comprises an at least partially unsaturated prepolymer including at least one of polyester and epoxy vinyl ester, and at least one vinyl or allyl containing monomer. The method further comprises subsequently injecting an aqueous, non-aqueous liquid or a gas for re-establishing permeability of the formation and letting the composition cure by free radical polymerization in the sand bearing formation at a temperature of 0-150° C. to form a cured sand consolidating material.
    • 一种方法是将颗粒物质固结在一个井中。 该方法包括将组合物注入含砂地层中。 该组合物包含可固化的非水均匀液体,用于热诱导产生自由基的引发剂,用于稳定自由基的适用期延长抑制剂,以及任选的促进剂和任选的填料。 非水均匀液体还包含至少部分不饱和的预聚物,其包括聚酯和环氧乙烯基酯以及至少一种含乙烯基或烯丙基的单体中的至少一种。 该方法还包括随后注入水性非水液体或气体以重新建立地层的渗透性,并使组合物在含砂地层中的自由基聚合在0-150℃的温度下固化,以形成 固化砂整理材料。
