Simulation and Optimization of Hydraulics Applied in Oil Well Drilling
Abstract: The main objective of hydraulics applied in oil well drilling is to ensure cleanliness at the bottom of the well, this consists of keeping in continuous movement the solids or cuttings of the formation, transporting the largest amount of them from the bottom and the annular space to the surface, thus minimizing the existence of unwanted events such as sticking, entrapment, among others. Each oil well has specific geological, geophysical and geomechanical characteristics that must be taken into account for its design, based on technical and scientific considerations that allow the establishment of its mechanical state and its exploitation engineering studies. The rheological behavior of a fluid in these wells cannot be generalized, even if they are separated by a few hundred meters. This paper describes the development of a graphical computational model for the fast and efficient calculation of the various hydraulic aspects associated with onshore oil well drilling. The model is arranged in three stages: First, the position of the drill pipes in the drillstring is evaluated and their pull margin is determined. Then, the hydraulic calculation procedures of national and international companies are developed. Finally, rheological models (Bingham plastic and exponential law) are used for fluid behavior. The model was developed with Microsoft Visual Basic.
