Dynamic analysis software of whole well drill string in an oilfield
The whole well drill string dynamics analysis software includes pre-processing, calculation and analysis module and post-processing display part. The pre-processing part includes the input of drilling parameters and drill string parameters, the establishment of geometric model, the application of boundary conditions, mesh generation and data output and storage; The calculation and analysis module includes static analysis and frequency domain analysis; The post-processing part of dynamic characteristic calculation is mainly to further solve the strain and stress at each position of the drill string according to the data obtained from the core part of the calculation, form dynamic stress diagram and curve diagram, and make animation to observe the motion of the drill string conveniently and intuitively.
