Abstract: A fusible composition for use downhole comprises polymerisable thermoplastic resins selected from petroleum resins, copolymer alkylaromatic/cycloaliphatic resins, modified resins containing hydroxyl or carboxyl groups, such resins being selectable to be thermally cured yet remain flexible upon curing within selected temperature ranges, say 50-90 o C, 90-120 o C, 120-140 o C, and 140-160 o C or above, a polymerisation initiator, and an inorganic filler such as particulate forms of limestone, marble, granite, clay, shale, ground salt, calcium carbonate, calcium oxide, dolomite, or mixtures of the aforesaid fillers, the resin and filler being mixable and deliverable downhole in a fluid such that in use under the temperature and pressure conditions typically encountered downhole the resin cures in the composition, to form a fused flexible concretion.

Abstract translation: 用于井下的可熔组合物包括可从石油树脂，共聚烷基芳族化合物/脂环族树脂，含羟基或羧基的改性树脂中选择的可热固化的可聚合热塑性树脂，这些树脂可选择热固化，但在选定的温度范围内固化时保持柔韧性， 90℃，90-120℃，120-140℃，和140-160℃。 聚合引发剂和无机填料，例如石灰石，大理石，花岗岩，粘土，页岩，研磨盐，碳酸钙，氧化钙，白云石或上述填料的混合物的颗粒形式的无机填料，该树脂和填料是可混合的 并且在流体中可进入井下，使得在通常在井下遇到的温度和压力条件下树脂在组合物中固化，从而形成熔融的柔性凝结物。
