    • The corrosion and fouling of metal surfaces in contact with corrosive acid fluids or acid salts in the presence of an aqueous medium is reduced by contacting the surfaces with a composition which comprises (a) an anti-fouling amount of a hydroxyl amine compound of the formulaR.sub.1 R.sub.2 N--OHwherein R.sub.1 and R.sub.2 are independently hydrogen or a hydrocarbyl or inertly substituted hydrocarbyl or both R.sub.1 and R.sub.2 are collectively a divalent hydrocarbyl combined with said nitrogen to form a heterocyclic ring, and (b) a corrosion-inhibiting amount of a reaction product of or a mixture for the purpose of a reaction product of a polyalkylene polyamine and an alkynediol. The polyalkylene polyamine is one that contains from 2-10 amine groups, each separated from another by an alkylene group having from 2-6 carbon atoms. The alkynediol has from 2 to 6 carbon atoms.
    • 在水性介质存在下,与腐蚀性酸性流体或酸式盐接触的金属表面的腐蚀和结垢通过使表面与包含(a)抗结垢量的式 R1R2N-OH其中R1和R2独立地是氢或烃基或惰性取代的烃基,或者R1和R2两者一起是与所述氮组合形成杂环的二价烃基,和(b)腐蚀抑制量的反应产物 的聚亚烷基多胺和炔二醇的反应产物的混合物。 聚亚烷基多胺是含有2-10个胺基的聚亚烷基多胺,各自由具有2-6个碳原子的亚烷基彼此分开。 炔二醇具有2至6个碳原子。

    • A water-based drilling fluid and method of using same are presented in this disclosure, which fluid is used in drilling wells through a formation containing a shale that swells in the presence of water. The drilling fluid comprises an aqueous based continuous phase; a weighting material; and a shale hydration inhibition agent (SHIA) selected from the group consisting of propylamine derivatives, hydrogenated poly(propyleneimine) dendrimers (HPPID), and polyamine twin dendrimers (PTD). In some embodiments, the SHIA of this disclosure is not hydrolyzed at a temperature in the range of from about 100° F. to about 500° F. The drilling fluid may further comprise a fluid loss control agent, an encapsulating agent, other additives, and combinations thereof. A method of reducing shale swelling during wellbore drilling is also described. The method comprises circulating in the subterranean well a water-based drilling fluid comprising an aqueous based continuous phase, a weighting material, and a SHIA.
