摘要:
Methods are provided for increasing the temperature of a section of conduit used for the production or transmission of hydrocarbon. According to one aspect, the method includes the steps of: (a) forming a treatment fluid comprising: (i) a carrier fluid; and (ii) a first reactant and a second reactant; and (b) introducing the treatment fluid into a section of conduit used for the production or transmission of hydrocarbon. The first reactant and second reactant are selected for being capable of reacting together in an exothermic chemical reaction; and the first and second reactant are in at least sufficient concentrations in the carrier fluid to generate a theoretical heat of reaction of at least 1,000 kJ/liter of the treatment fluid. At least some of at least one of the first reactant and the second reactant is suspended in the carrier fluid in a solid form that is adapted to help control the release of the reactant into the carrier fluid.
