So in this thesis, we have established a model to calculate the temperature and pressure in the wellbore. We make some amelioration on the basis of others’research, including: density and rheological behavior of drilling fluid are deemed as a function of temperature and pressure; the effect of cuttings, frictional heat and pressure-drop heat are taken into consideration; what’s more, the temperature and pressure in the wellbore are coupled calculated.
本文根据此需要,建立了深水钻井井筒内温度和压力计算模型,与其他模型不同的是,此模型把钻井液的密度、粘度等考虑成温度和压力的函数,引入了岩屑的影响,摩擦生热和压降生热的影响,并把温度和压力进行了耦合计算,使模型更加贴近实际,计算结果更加精确。
