SUMMARY:

The objective of this work is to evaluate the influence of the joint action of axial stresses and pressures on the calculations for checking the integrity of casing tubes. This assessment is relevant because, in well projects, some scenarios submitted to combined loads are capable of penalizing the resistance to collapse, which can cause an unexpected failure in the casing. Due to the complexity of the problem, numerical simulations supported by the finite element method are used to reproduce the evaluated scenarios. To achieve the proposed objective, the development methodology of this work is based on four main steps: i) determination of study scenarios; ii) determination of loads; iii) determination of the type of modeling; and iv) numerical simulation and evaluation of results. To reach the proposed objective, the development methodology of this work is based on four main steps: i) study and determination of the scenarios that the casing tubes must be submitted to; ii) determination of loads, including studies of the effects and phenomena that act on the casing; iii) identification of the most adequate numerical modeling for the reproduction of scenarios considering the fully modeled casing tubes and the various possibilities of combined loading that act on these tubes; and iv) carrying out numerical analyzes considering the different scenarios considered and evaluating critical situations that may lead to a failure in the integrity of the coating. At the end of the work, it is expected to fully analyze the coating structure from the axial stress fields and resulting pressure stresses obtained in the numerical simulations, finding the most critical sections in relation to loading and strength and evaluating the integrity of the casing more effectively.
