摘要
为了解生产井段产出或吸入流体的性质和流量,对油井生产状况和油层生产性质作出评价,应用分布式光纤温度传感系统进行油气田开发动态监测。分布式光纤温度系统是一种用于实时测量空间温度场分布的传感系统,它通过沿整个完井长度连续性采集温度资料来监测油气田开发动态。介绍了分布式光纤温度传感系统测量原理和井下测量方式,研究了生产井内温度分布特性及热交换模型。根据井内流体温度和地层温度资料的对比分析,提出了相应的半定量解释处理方法。对现场实测资料进行了处理解释,结果与实际生产情况相符,表明所提出的解释方法可行。
In order to know the character and flowrate of yield or input fluid in production well,and to evaluate the production status and character of oil well,the optical fiber distributed temperature measurement system is used to do performance monitoring for oil-gas reservoir development.The optical fiber distributed temperature measurement system is developed for the real-time measurement of temperature field in space,which can monitor the reservoir development by continuously collecting well temperature data in the production well.Introduced are the system's principle and downhole measurement styles,and the temperature distribution and heat transfer model in the producing wells are studied.Based on the analysis of the dowenhole fluid temperature and the formation temperature data,corresponding log data processing method is put forward.The log application result indicates that the above model and the processing method are feasible with good effect.
