Integrity Analysis of Gas Field Water Reinjection Well Wellbore

Finding the right abandoned well (or new drilling ) leakage layer reinjection into the ground is the most effective, the most mature, the most commonly used method in the gas filed water treatment. By simplifying assumptions and the establishment of mathematical model and FEM, simulation and calculation of stress status of the tubing and casing, Analysis of wellbore integrity, for the analysis of the wellbore risk of gas field water reinjection wells and reinjection wells safety operation provide important theoretical support.
