| 摘 要： | 海洋钻井诸多问题的解决都依赖于井筒内温度的准确确定。根据能量守恒原理,推导出了海洋深水钻井温度场的控制方程,包括环空内、钻杆内以及地层内的温度场方程,并给出了方程求解的定解条件。计算结果表明：环空内的温度会受到钻井液密度和循环流量的影响,密度越大、流量越低,环空温度越接近于外部环境温度。

| Abstract: | The wellbore temperature must be calculated accurately in order to solve many problems in offshore drilling. According to principle of conversation of energy, the temperature control equations are established including annulus, drill pipe and formation temperature equations and definite conditions of these equations were given. The results showed that wellbore temperature could be affected by drilling fluid density and circulation volume, and wellbore temperature was getting close to ambient temperature when drilling fluid density became heavier or circulation volume became lower. |

| Keywords: | marine drilling borehole temperature drilling fluid density circulation volume |
