井下温度计算
摘要：
本发明公开了一种计算表示烃类井中的井下温度的值的方法。该井包括在外管路(4)内侧的生产管路（3），在生产管路与外管路之间设有环形空间，该环形空间接纳液压控制线（2），液压控制线用来供应液压流体以控制井下装置(1)。该方法包括：感测井口处控制线中的液压流体的压力并且使用该压力的测量值来计算表示井下温度的值。
摘要（英）：

A method is disclosed calculating a value representative of a downhole temperature in a hydrocarbon well. The well comprises production tubing (3) inside outer tubing (4), there being an annulus between the production tubing and the outer tubing, which annulus receives a hydraulic control line (2) supplying hydraulic fluid for the control of a downhole device (1). The method comprises sensing the pressure of hydraulic fluid in the control line at the wellhead and using a measurement of that pressure to calculate a value representative of a downhole temperature.
