news 21 September 2016 Corrosion protection in the reservoir pressure maintenance system in the service of environmental safety OAO TATNEFT, within the framework of a large-scale work to ensure environmental safety in oil production, is implementing a number of promising projects, including anti-corrosion protection of oil field equipment of the reservoir pressure maintenance system in order to minimize its accident rate. Thus, a program is being implemented to introduce anticorrosive tubing into injection wells, which makes it possible to increase their service life in wells by 2-2.5 times. Based on the results of work for 2004-2009. the protection of the existing stock of injection wells injecting waste water from tubing in anticorrosive design exceeded 77%. At the same time, the implementation of highly reliable M1-X packers in injection wells is being implemented, which, together with anti-corrosion tubing, allows to reliably protect the production string of wells from high pressure and corrosion. In total, more than 2 thousand injection wells are equipped with such packers. Implementation of these programs will lead to a reduction in well workover costs, a decrease in pollution of the bottomhole formation zone with corrosion products, and a reduction in well survey costs. The total cumulative estimated economic effect from the implementation of these programs for the period 2004-2009. will exceed 900 million rubles Back to news list © 2010 Tatintek Group of Companies
