Ammonium salt is a chelating agent, as well as their use in applications of gas fields and oil

摘要

The present invention relates to method of treating subterranean formations, in this way, fluid containing glutamic acid N, N N- methyl glycine diacetic acid or (GLDA), an ammonium salt N- two acetic acid (MGDA) is introduced into the formation . The present invention, the ammonium salt of MGDA GLDA and / or, as well as seawater, a mutual solvent, anti-sludge agents, surfactants (or emulsified water-wet), foaming agents, corrosion inhibitors, corrosion inhibitors reinforcing agents, elephants gums, wetting agents, antiepileptics, oxygen scavengers, carrier fluid, fluid loss control additives, friction reducing agents, stabilizers, rheology modifiers, gelling agents, scale inhibitors, disruption agents, salts, brine, pH control additive from the group of coagulants, biocides / bactericides, granules, cross-linking agents, salt substitutes (eg, tetramethylammonium chloride), relative permeability modifiers, sulfide scavengers, fibers, nanoparticles, It includes a fluid containing at least one component.
