摘要： Methods for delivering treatment chemicals into a subterranean formation using treatment fluids that include nanoemulsions are provided. In some embodiments, the methods include providing a treatment fluid including an aqueous base fluid and a nanoemulsion including a water-soluble internal phase, a water-soluble external phase, and a surfactant, the nanoemulsion being formed by mechanically-induced shear rupturing; and introducing the treatment fluid into at least a portion of a subterranean formation at or above a pressure sufficient to create or enhance at least one fracture in the subterranean formation.

摘要： A treatment fluid for treating iron sulfide and hydrogen sulfide can include a first additive of acrolein that provides a dual function to dissolve iron compounds and scavenge hydrogen sulfide. After dissolution of the iron compounds, free iron is formed, which can react to form iron oxide. The iron oxide can reprecipitate out of the solution. The treatment fluid can also include a second additive that is a chelating agent to chelate the free iron formed. The chelating agent can be a sugar acid. The two additives are compatible with each other and provide a synergistic effect with improved performance compared to the use of either additive alone.
