    摘要: An acid treatment composition is provided including a corrosion inhibitor and an optional corrosion inhibitor intensifier in an acidic solution. More specifically, the composition includes a propargylalcohol alkoxylated compound. Methods for treating wells with these acid treatment compositions are also provided that help control corrosion of the steel used in the wells during the acid treatment.

    摘要: A formulation containing a copolymer derived from a cationic monomer effectively inhibits and controls the formation of inorganic scales. The formulation has particular application in the removal of zinc sulfide and iron sulfide scales formed when zinc bromide brines are used as completion fluids. The copolymer exhibit high solubility in high-density brines, such as zinc bromide brines. The polymers may be introduced into an oil or gas well as a portion of a carrier fluid or with brine. The preferred copolymer for use in the invention contains an acrylamide unit and a diallyldimethylammonium salt and, optionally, an acrylic acid or a salt thereof. The weight average molecular weight of such inhibitor copolymers is generally between from about 500,000 to about 5,000,000.
