METHOD FOR PREDICTING THE TECHNICAL CONDITION OF GAS WELL TUBING WITH CORRECTION BASED ON IN-LINE DIAGNOSTICS INFORMATION
(pp. 28-34)

Abstract. The article presents a methodology for monitoring and predicting the technical condition of the suspension of pump-compressor pipes (tubing) of gas wells exposed to carbon dioxide corrosion. The tubing suspension as an object of control and diagnostics is considered, the main loads acting on the object in question are determined, as well as the expression for the equivalent value of the loads. An expression has been obtained for determining the permissible reduction in the tubing wall thickness, provided that the facility remains operational, as well as an expression for determining the total and residual life of the tubing hanger.A comparative analysis of the main methods for determining the corrosion rate of a diagnostic object was carried out, and the optimal method was selected. A method for correcting the results of calculating the corrosion rate using tubing wall thickness values obtained during in-line diagnostics is described.

Keywords: wall thickness measurement, corrosion rate, tubing, service life, mechanical loads, in-pipe diagnostics.
