casing aluminum anode
Type:Aluminum alloy CP
Features:Structure and working principle of casing anode: it is composed of metal body and alloy anode. An anode protector is used to provide an anode to the surface of the casing to be protected, so that the anode alloy is sacrificed, so that the casing (cathode) to be protected is reduced or mitigated from corrosion.
Release DATE:2021-06-29
Corrosion is in the process of oilfield development effect on production and wellbore oil and water Wells is very serious phenomenon, caused by oil and water Wells casing corrosion perforation of oil and water Wells is scrap, all kinds of pipeline corrosion perforation, equipment corrosion and frequent replacement and scrapping, underground pipe rod pump, shorten operation cycle and so on, causes because of corrosion damage were bring huge economic losses to the production of oilfield.Corrosion is the nature of the metal surface ionizes the atoms, the corrosion electric chemical is more apparent in the electrolyte, the ground of the oil field using underground pipe is in the ground or in well liquid electrolyte solution, due to the metal surface corrosion of metal caused by the galvanic effect between, is an obvious feature of oilfield corrosion.In particular, the electrochemical corrosion caused by different metal materials used in oil and water Wells is especially obvious.
Product type: casing aluminum anode
Scope of application: This product is applied to new drilling and lateral drilling,is characterized by casing through the salt paste layer and other media corrosion strong new drilling and lateral drilling casing corrosion protectionStructure and working principle of casing anode: it is composed of metal body and alloy anode. An anode protector is used to provide an anode to the surface of the casing to be protected,so that the anode alloy is sacrificed, so that the casing (cathode) to be protected is reduced or mitigated from corrosion.
Casing anode appearance size:
