在油田勘探开发过程中,油层温度和井内流体温度的变化是非常重要的参数和信息。温度测井是用电缆将温度仪下入井内,测量和记录某一深度的井温或沿井剖面的温度变化。温度测井资料可用于确定油层温度,了解井内流体流动状态,划分注入剖面,确定产气、产液口位置,检查管柱泄漏、串槽,等多个方面。本文就从以上几方面讨论了温度测井在油气田开发中的应用。 In the process of oilfield exploration and development, the change of reservoir temperature and well fluid temperature are very important parameters and information. Temperature logging is the use of a cable to lower the thermometer into the well, measuring and recording temperature changes at a well depth or along a well profile at a certain depth. Temperature logging data can be used to determine reservoir temperature, understand fluid flow in the well, divide the injection profile, determine gas production, liquid production port location, check the string leakage, string slot, and so on. This article discusses the application of temperature logging in the development of oil and gas fields from the above aspects.
