SRPRDES 3D
DESIGN, PREDICTION, OPTIMIZATION, EVALUATION and DATA MATCHING of ROD SYSTEMS in DIRECTIONAL WELLS
SRPUMP 3D is a user-friendly and at the same time powerful software for the automatic design, prediction, optimization and evaluation of the performance of the sucker rod in directional wells. Rigorous stress analysis procedures ensure the highest accuracy of calculations. The program uses inclination and azimuth angles to describe accurately the geometry of the well. Two wave longitudinal and transverse equations and exact pumping unit's kinematics used in the mathematical model make it possible to asses the dynamic stability of the examined system.
SRPUMP 3D is the only program performing calculations using two - wave equations for longitudinal and transverse vibrations. The rod in three - dimensional deviated or directional well vibrates not only along the tubing but also in the transverse direction, in the annulus. This vibration changes the axial stiffness of the rod and rod buckling performance. The program calculates the friction forces and normal forces between the rod and the tubing. SRPUMP 3D also includes the calculations of the buckling forces, loss of the axial stiffness from lateral and helical buckling. It defines the exact location and number of rod guides necessary to prevent the contact of the rod with the tubing.
SRPUMP 3D integrates two computer programs: SRPDES 3D (design, prediction, optimization) and SRPEV 3D (evaluation) which are also available separately. By combining design and evaluation with the implementation of data matching SRPUMP 3D allows to define the best design parameters to achieve the optimum performance of the designed system. Although SRPUMP 3D has been developed for directional wells, it can also be used for vertical systems.
