METHOD FOR DETERMINING THE THERMAL PROFILE OF A DRILLING FLUID IN A WELL

摘要

Method for determining in real time a thermal profile of the drilling fluid in a well from three measurement points available on site, that is to say the injection, outlet and downhole temperatures. The shape of the profile between these three points is defined by a standard curve representative of the thermal profiles in a well being drilled, estimated from physical considerations on the heat transfers in the well.
