摘要： A corrosion measuring tool for controlling corrosion in an oil well comprising a tubing, wherein the tool comprises a hollow cylindrical barrel comprising a cylindrical wall, an upper end and a lower end; a hollow element located at the upper end of the hollow cylindrical barrel, wherein said hollow element comprises a conical upper portion and a cylindrical lower portion, the cylindrical lower portion being capable of sliding within the upper end of the barrel, wherein the cylindrical lower portion has linkage and retention sliding means to link and retain the hollow cylindrical barrel; expandable means located at the upper end of the hollow cylindrical barrel, below the conical upper portion, comprising fastening means to the tubing, wherein the movement of the hollow element relative to the barrel in a downwardly direction causes the conical upper portion to penetrate into the expandable means, forcing the expandable means to expand outwardly, putting in contact said fastening means with the tubing, while the movement of the hollow element in an upwardly direction releases the expandable means to retract inwardly and separates de fastening means from the tubing; at least one coupon for corrosion measurement; and an elongated member longitudinally and eccentrically fixed at the lower end of the barrel comprising mounting means for each of the at least one coupon, wherein the mounting means are aligned along the elongated member.

摘要： A corrosion measuring tool for controlling corrosion in an oil well with a tubing has a hollow cylindrical barrel, a hollow element, an expandable sleeve, at least one coupon for corrosion measurement and an elongated member. The hollow element is located at the upper end of the hollow cylindrical barrel and has a conical upper portion and a cylindrical lower portion. The cylindrical lower portion is slidable within the barrel. The cylindrical lower portion has linkage and sliding retention. An expandable sleeve is located at the upper end of the hollow cylindrical barrel, below the conical upper portion. The sleeve has a fastener. Movement of the hollow element relative to the barrel in a downward direction causes the conical upper portion to expand the expandable sleeve. Movement of the hollow element in an upwardly direction releases the expandable sleeve to separate the fastener from the tubing.
