摘要: Compositions containing a first reactant; an emulsion comprising a surfactant and silicon dioxide (SiO2) nanoparticles; and a carrier fluid containing a second reactant and methods of making. When the first and second reactants react, they generate heat. At a first time, the emulsion surrounds the first reactant, and the carrier fluid with the second reactant surrounds the emulsion. At a second time, the emulsion surrounds a first portion of the first reactant; and a second portion of the first reactant surrounds the emulsion.

摘要: A ternary water control and gas recovery method suitable for an unconsolidated siltstone gas reservoir is provided. It includes the following steps: first, running a silt control screen pipe manufactured by an interface hydrophobic modification into a wellbore to realize wellbore water control and silt control; second, filling a surface hydrophobic modified gravel in an annular space between the silt control screen pipe and the wellbore to form a hydrophobic gravel packing layer for water control and silt control; third, injecting a wetting agent aqueous solution into a stratum, and performing a hydrophobic modification on a gas reservoir seepage channel surface to realize in-situ water blocking and silt migration of the unconsolidated siltstone gas reservoir, and then closing a well for a preset time before exploitation.

摘要: A temporary high-temperature-resistant dispersing agent, and a preparation and a use method thereof. The temporary high-temperature-resistant dispersing agent is a block high-molecular polymer prepared by a one-step reaction from polysiloxane containing an amino group. The prepared block high-molecular polymer may be directly used as a dispersant; the block high-molecular polymer may also be used as a basic formula and used as the dispersant after other auxiliary compositions are added; and the block high-molecular polymer may also be used in combination with one or more other dispersion auxiliaries and/or surfactants to meet dispersion requirements in various special occasions.

摘要: A process for coating a product by ion exchange including: a) providing a product that contains a surface segregating species (SSS) having a low surface energy component and an ionic component wherein the SSS has segregated to an outer surface of the product to form an activated surface; and b) treating the activated surface of the product with a liquid containing a surface modifying agent comprising one or more polyionic species, wherein the polyionic species is attracted to and deposits on the activated surface through a process of ion exchange.

摘要: Methods and compositions for enhancing wellbores and propped fractures for use in geothermal operations are provided. In some embodiments, the methods comprise: drilling with a drilling composition at least a portion of a first wellbore, wherein the drilling composition comprises a base fluid, a resin, and a thermally conductive filler; introducing a fracturing fluid into the first wellbore at a first pressure sufficient to create at least a first set of fractures extending from and in fluid communication with the first wellbore; and introducing a first plurality of proppant particulates into at least the first set of fractures, wherein a second wellbore penetrates at least a second portion of the subterranean formation, and wherein a second set of fractures extends from and is in fluid communication with the second wellbore into the subterranean formation, and the first set of fractures is in fluid communication with the second set of fractures.
