Paper Title:
Influence of Casing Inner Wall Corrosion on Internal Pressure Strength
  Abstract

Considering the differences of pressure and temperature along well depth, the distribution law of casing inner wall corrosion rate was calculated with the Norsok model. According to the measured pressure values, the law of well pressure changing with the time can be obtained with the empirical method or the derivative curve method. Then the changing laws of the corrosion rate and the thickness reduction of casing inner wall are derived during the casing service life. Finally, the time-varying characteristic of casing internal pressure strength influenced by corrosion is researched.
