A PC Simulation of Heat Transfer and Temperature Distribution in a Circulating Wellbore.

Abstract

The ability to accurately predict temperatures in a circulating wellbore is probably more critical today than at any time in the history of drilling oil wells. Due to the increasing depths to which wells are being drilled, accurate methods and procedures are needed to predict fluid temperatures during circulation operations. These methods and procedures would be used to provide accurate data for designing drilling mud systems and cement jobs for these deep, hot wells. Though the problem of accurately predicting temperatures in a wellbore has existed since engineers first began searching for oil at greater depths, relatively little has been done to address this problem. In the past it has been convenient to ignore temperature gradients, largely because no practical means for estimating wellbore temperature profiles have been available. Determining accurate temperature distributions in a circulating wellbore is very important for many aspects of drilling, completion, production, and injection. Numerous large-scale temperature simulators have been developed by many researchers. However, these simulators are restricted in their applicability because of their complexity and limited portability. As an alternative, a model has been developed for the personal computer which is portable, flexible, and easy to use.
