IMPROVEMENT OF THE ANTI-CORROSIVE DOWNHOLE EQUIPMENT PROTECTION

 

Background

Electrochemical metal protection system is based on the dependence of corrosion rate on electrode potential. Electrochemical corrosion protection is widely used but remains as a highly relevant problem. As a result, it is recommended to use the anchored installations of Research and Production Company Paker, which corrects the electrochemical corrosion.

Aims and Objectives

To evaluate the efficiency of the recommended methods of electrochemical corrosion protection.

To show that transition for more powerful and highly-performance pumps causes the decrease of mean time between failures.

Methods

The solution of these issues are made by experimental studies by known methods and standards.

Results

Work deals with analysis of oil reservoir corrosion protection methods and their efficiency.

 

Key words: electrochemical corrosion protection, inhibitors, anchored installation, well, annular space, corrosion.
