TARGETING ENHANCED PRODUCTION THROUGH DEEP CARBONATE STIMULATION: STABILIZED ACID EMULSIONS CONTAINING INSOLUBLE SOLID MATERIALS WITH DESIRED WETTING PROPERTIES

摘要

A stabilized emulsified acid composition for deep carbonate formation stimulation is provided. The stabilized acid emulsion composition includes a petroleum operable to provide a barrier between an acid and a reservoir rock, the acid operable to react with the reservoir rock to dissolve the reservoir rock and produce a wormhole, a functional framework operable to stabilize the stabilized acid emulsion, an emulsifier operable to stabilize the stabilized acid emulsion, and a corrosion inhibitor operable to provide protection against corrosion for the metal components of a well. The petroleum can be diesel. The acid can be hydrochloric acid. The functional framework can be selected from the group comprising surface-modified clay-based material, zeolites, hybrid organic-inorganic materials, covalent-organic framework materials, and boron nitride nano tubes, and combinations thereof. The functional framework can be a surface-modified clay material selected from an organoclay. The corrosion inhibitor is a cationic ammonium-based corrosion inhibitor.
