According to the director of technical department «Orenburgnefti» Yuri Makarova, one of directions of defence of pipeline park is inhibition (application of chemical technology, which creation of protective tape is the basis of into the cavity of pipe). It allows to prevent the contact of aggressive environment with a metal which a pipe is made from. At the end of 2005 on the assets of NGDU «Buzulukneft’» new approach, which consists in that khimreagent is given directly in an extractive mining hole, was tested.
The same under defence both a pogruzhnoe equipment and surface pipelines is put. A pilot project, as Yuri Makarov told, was realized on Gerasimovskom deposit, where soon and more than promising results were got: accident rate
on this deposit mionectic on 90%. For subsequent two years a similar method was used more than on 20 deposits. «In addition, from the last year we began to use another method of corrosion protection, directed on the maintainance of pipelines with naruzhnoy
parties. It is electrochemical defence. In oil industry this method is used already many years, for example, for defence of main pipelines of such large company, as AK «Transneft’», – Yuri Makarov talks. – We adapted this method to the terms of obustroystva
our deposits and suppose annually a poryadka 400 km to put under such defence. In particular, this year in the business plan of extractive production units editing is foreseen poryadka 40 stations of cathode defence». It is needed to mark that, in spite of difficult economic
situation, the orenburgskie enterprises of TNK-VR continue to realize all measures on the maintainance of reliability of the pipeline systems. In particular, only on inhibition it is this year planned to send a 203 million rub, while this number made last year
182 million rub On other method of defence – electrochemical – a 96 million rub will be selected this year, that on 40% more than last year.
