The Development And Application Of The Solid Corrosion And Scale Inhibition Bar

At present, most of the oil has entered the oil development in the latter part of a larger water content produced fluid, along with increased water content, well casing corrosion and scaling problems await. Among the corrosion inhibition process, the oil, gas in liquid scale and corrosion inhibitor dosing is commonly used and most cost-effective corrosion inhibition as a measure of protection but there are short, protection of small, labor intensity Dosing Higher shortcomings. To overcome the above-mentioned liquid-based corrosion inhibitor shortcomings, there is need to develop sustained-release type of solid corrosion and scale inhibitors.Through a large number of laboratory tests and field tests, developed oil field scale and corrosion inhibitor with solid rods, corrosion rate can reach more than95%inhibition rate to80%or more. Liquid corrosion inhibitor for application in the field deficiencies and shortcomings in the proposed development of solid corrosion and scale bar adding to the bottom of the corrosion scale prevention ideas. Indoors through the screening and comprehensive evaluation, selection, and compounding the high solid corrosion and scale inhibitor. Pharmacy in the forming process of solid domestic and abroad, based on suppression method is proposed for mixed processing, processing to produce finished products of solid corrosion and scale bar. After the success of product development, oil production plant in the Changqing oil field was the second field test, get a good corrosion inhibition, scale inhibition test results.Solid stick corrosion and scale well to overcome the shortcomings of liquid agents can not only inhibit the occurrence of corrosion and scaling, and can save a lot of financial and material resources, help to improve the utilization of oil resources, and promote the great development of oil fields.
