| 摘 要： | 完善了由微差井温测试资料确定原始油藏导热系数的理论，分析了钻井、完井或洗井造成井筒及近井带地层冷却对后期温度恢复过程的影响，提出了由井筒内流体介质温度测试资料反推对应地层温度曲线的方法．分析了热平衡状态下井筒本身的存在造成井筒内测试温度与实际地温的偏差及对地层导热系数计算结果的影响．

| Abstract: | The theory for in-situ determination of geothermal conductivity by using accurate well temperature logs is presented. The influence of wellbore cooling by operations of drilling and other cold fluid circulating on wellbore temperature recovering is analyzed. The method of calculating original geothermal temperature from temperature recordings in the wellbore fluid is given. The difference between the temperature recordings in wellbore fluid and actual geothermal temperature as well as its influence on geothermal conductivity calculation is also provided.. |
