Abstract Details

2002, MS, University of Cincinnati, Engineering : Engineering Mechanics.
Many projects have been carried out to reach the oil reservoirs with minimum time and cost. In the 1950s, an importanat improvement was achived when fluid was injected in the well bottom aera through nozzles placed in the drill bit body. This fluid helps to increase mixing and turbulence at the bottom of the well The flow of the drilling fluid is a main factor insuring efficiency in the drilling process. Security-DBS a division of Dresser Industries Inc. decided to study these aspects by testing new nozzles and by comparing the efficiency of these geometries with regard to a conventional one by measuring the well floor pressure, turbulence and vortex created. This project aims to design and construct a new testing facility at the Fluid Mechanics and Propulsion Laboratory of the Department of Aerospace Engineering and Engineering Mechanics at the University of Cincinnati. Owing to this facility, several measurements have been performed on a Security-DBS roller cone bit. The acquisition of the pressure map on the well floor and the visualization of the flow field around the bit are the main targets. The goal of the current project is to test these new nozzle designs in a more realistic drilling environment .The results will show the influences of different nozzle geometries on drill bit performance. The most important ones are the cleaning of the annulus and the bottom hole, the lubrication of the bit and the removal of the cuttings.
