Ramey井筒传热方程的改进与应用
摘要
Abstract
Ramey's theory of wellbore heat transmission is the basis of the prediction of flowing temperature in gas well. However, Ramey failed to take the heat generated by friction work along flowing inner-surface into consideration. Based on the first law of thermodynamics, wellbore heat transmission problem is studied again and a new theoretical model considering frictional item is derived in the paper. Flowing profile of Keshen-1 condensate well in Tarim Oilfield is predicted by integrating our modified equation of wellbore heat transmission, equation of pipe flowing pressure calculation and PR-EOS for phase behavior characterization. Simulation results show that heat generated by frictional can not be omitted when production rate is high enough.关键词
