Abstract

Purpose

The purpose of this paper is to solve the tubing corrosion problem of B Block on the Right Bank of Amu Darya river sour gas field.

Design/methodology/approach

By using four-point-bending method, the tubing’s ability to resist sulfide-stress cracking was tested. Simulating the wellbore corrosive environment, the corrosion inhibitor which was suitable for gas filed had been screened. According to the characteristic of Amu Darya river gas field, the corrosion monitor system had been designed.

Findings

From the feedback of wellbore corrosion monitor result, the corrosion rate was lower than 0.076 mm/a.

Originality/value

This anti-corrosion technique provides security for the development of gas field.
