摘　　要：温度监测与其他井下实时监测方法相比较有很多优势,在近年来的智能井技术中起到很大作用,尤其对超高压井的意义更为重要。井下温度场分布的研究是井温测井的理论基础。充分考虑超高压条件对流体物性的影响,根据能量守恒方程建立了一维温度场数学模型,模拟超高压油井定流量生产时油藏产出流体温度情况。数值模拟结果表明,入井流体温度由于焦耳-汤普森效应和热传递作用而发生温度变化,并且生产压差越大、流量越大时,入井流体温度越高。Temperature surveillance which has a profound effect on intelligent well systems has many advantages compared with other reservoir surveillance technologies. The research of downhole temperature distribution is the theoretical basis of temperature surveillance. Considered are the effects on fluid physical propertied by ultrahigh pressure, then developed is the 1-D temperature field mathematical model. Simulated are the case of downhole temperature distribution in ultrahigh pressure wells with constant rate. Mathematical simulation results show that the downhole temperature is changed because of Joule-Thomson Effect and heat transfer effect. The greater production pressure and the greater the flow rate, the greater the fluid into the well temperature is higher.
