      分布式光纖監測設備可實時監測沿井筒的聲波分布數據,并利用辰工光纖聲波數據(DAS)解釋軟件V1.0解釋出所需的油氣參數。一根光纖和一個反演軟件可反演出油氣井的注產剖面、套管竄流及泄漏等,直接取代十幾種常規測井儀器,正逐漸成為油氣田勘探開發的顛覆性技術。分布式光纖監測不僅關系到非常規油氣勘探開發的戰略部署,而且在地熱、采礦、煤田開發及油氣管道監測等方面也有重大應用,對深部資源開發具有重大戰略意義。

      基礎功能

      導入數據,文件解析,得到光纖分布分析圖像,繪制氣液活動區域

      頻譜分析,得到不同時間選定深度的頻譜分析圖。溫度分析:提供不同制度數據導入功能,進行曲線濾波和溫度、壓力光纖數據預處理操作

      特色功能

      突破海量聲波(DAS)數據的高效傳輸技術瓶頸:基于能量譜信號特征提取高效算法,實現TB級數據的高效壓縮與傳輸,數據壓縮達到10000倍

      軟件數學算法研究:TB級數據的可視化無延遲刷新算法研究

      光纖測試井下聲波數據是基于光纖對振動的敏感性,但是光纖測試的過程中是將光纖貫穿于連續油管當中,并注入一定濃度的鹽水。由于在測試過程中,無論是注入井和還是生產井,測試的數據均來源于套管與連續油管的聲波振動,可以反演出每一段的射孔段的注入貢獻率

      軟件形成了數據輸入、數據處理、核心計算及可視化等算法組件,如高倍壓縮、快速讀取等數據處理算法組件,以及其他類型的組件。采用組件技術,將辰工光纖聲波數據(DAS)解釋軟件V1.0的數據處理、繪制圖形等組件進行集成形成軟件

      The warning of drilling engineering accidents is a long and continuous process. The sight changes of key parameters are often the precursors of accidents, so it is necessary to capture the changes of real-time parameters efficiently, accurately, carefully and quickly, and to analyze the changing trend of various parameters and the dynamic probability of engineering accidents in real time. The software is suitable for automatic warning of single well and multi-well, and can realize the functions of real-time acquisition of field data, alarm information storage, automatic alarm and alarm viewing.

      Establish the judgment model of logging abnormal working condition: Investigating the research data from domestic and abroad with the experienced engineers of the logging companies, collecting the abnormal and accident cases of the drilling engineering, analyzing the engineering accidents by combining the engineering theory, sorting out and concluding the performance characteristics, and establishing engineering abnormality and accident analysis judgment model.

      Establish automatic warning inference rule: According to the established engineering anomaly judgment model, select the key monitoring parameters, set the upper and lower thresholds of the parameters, the drilling state, and establish the automatic alarm judgment rule through the flexible logic relation and the weight coefficient.
