Torque and Drag Friction Model: Implemented Friction Factor Dependency of Temperature
MetadataVis full innførsel
We investigated the friction factor dependency of temperature. “Friction factor” is a parameter in the calculations of torque and drag. Increased well reach is dependent on accurate torque and drag modeling. We proposed that the friction factor can be dependent on temperature other than linear approximations as studied by Kaarstad et al. . The results was implemented in the work of Aadnoy  torque and drag 3D model. The local friction factor in the wellbore was determined by a temperature model for local temperature in the wellbore and the result of the regression from the experimental work done with the tribology equipment in this thesis. We compared Aadnoy  model with the nuances done to the model presented. The findings may lead to thorough research in the area of temperature and friction, and torque and drag models that are used today. Wellbore friction is an important theme in modern drilling in its search for increased well reach.
