    摘要: According to an embodiment, a method for thermally insulating a portion of a tubular located inside an enclosed conduit comprises the steps of: (A) introducing a grouting composition into an annulus between the tubular and the enclosed conduit, the grouting composition comprising: (i) a water-swellable binding material comprising water-swellable clay; (ii) an aqueous liquid, wherein the aqueous liquid is the continuous phase of the grouting composition; and (iii) an insulating material; and (B) allowing the grouting composition to set after the step of introducing, wherein after setting the grouting composition has a thermal conductivity of less than 0.3 BTU/hr . ft . °F (0.5 w/m °C). According to another embodiment, a grouting composition for use in insulating a portion of a tubular located inside an enclosed conduit comprises: (A) a water-swellable binding material comprising water-swellable clay; (B) an aqueous liquid, wherein the aqueous liquid is the continuous phase of the grouting composition; and (C) an insulating material, wherein after the grouting composition has set, the grouting composition has a thermal conductivity of less than 0.3 BTU/hr . ft . °F (0.5 w/m °C).
