摘要

为了实现渤海油田蒸汽吞吐作业全周期井下温度实时监测,运用高温光纤光栅测温和分布式测温相互校正理论,采用顶封以上油管外部捆绑、顶封以下油管内部插入的工艺方法进行实时温度监测。试验表明,此监测技术空间分辨率0.5m、测温精度±1℃,且在满足耐温等级及监测精度的前提下,能够有效保证光缆下井过程中的安全性。该技术主要用于渤海油田热采井全井筒温度、油套环空、水平段温度长期实时监测。以L井为例分析了该技术的应用范围,并对应用效果及监测数据进行分析。测取注汽期间井底最高温度368.2℃,首次实现渤海油田热采井环空及水平段全井筒温度实时监测。
        In order to realize the real-time monitoring of the downhole temperature in the whole cycle of steam huff and puff in BoHai Oilfield, FBG and DTS Mutual correction theory are applied, and the method of externally bundling and sealing the inner tubing of the above oil pipe is adopted to realize temperature monitoring of all wellbore. The test shows that the monitoring technology, the monitoring technology has a spatial resolution of 0.5 m and a temperature measurement accuracy of 1 ℃. Under the premise of satisfying the temperature resistance level and monitoring accuracy, the safety of the cable can be effectively guaranteed.This technology is mainly used for long-term real-time monitoring of the whole wellbore temperature, oil jacket annulus and horizontal section temperature of thermal recovery wells in Bohai Oilfield. Taking L well as an example, the application range of the technology is analyzed, and the application effect and monitoring data are analyzed. The maximum temperature of the bottom hole during the steam injection was measured at 368.2 ℃. It is the first time to realize real-time monitoring of all wellbore temperature in the annulus and horizontal section of thermal production Wells in BoHai Oilfield.
