分布式光纤监测设备可实时监测沿井筒的声波分布数据，并利用辰工光纤声波数据(DAS)解释软件V1.0解释出所需的油气参数。一根光纤和一个反演软件可反演出油气井的注产剖面、套管窜流及泄漏等，直接取代十几种常规测井仪器，正逐渐成为油气田勘探开发的颠覆性技术。分布式光纤监测不仅关系到非常规油气勘探开发的战略部署，而且在地热、采矿、煤田开发及油气管道监测等方面也有重大应用，对深部资源开发具有重大战略意义。

基础功能

导入数据，文件解析，得到光纤分布分析图像，绘制气液活动区域

频谱分析，得到不同时间选定深度的频谱分析图。温度分析:提供不同制度数据导入功能，进行曲线滤波和温度、压力光纤数据预处理操作

特色功能

突破海量声波(DAS)数据的高效传输技术瓶颈：基于能量谱信号特征提取高效算法，实现TB级数据的高效压缩与传输，数据压缩达到10000倍

软件数学算法研究：TB级数据的可视化无延迟刷新算法研究

光纤测试井下声波数据是基于光纤对振动的敏感性，但是光纤测试的过程中是将光纤贯穿于连续油管当中，并注入一定浓度的盐水。由于在测试过程中，无论是注入井和还是生产井，测试的数据均来源于套管与连续油管的声波振动，可以反演出每一段的射孔段的注入贡献率

软件形成了数据输入、数据处理、核心计算及可视化等算法组件，如高倍压缩、快速读取等数据处理算法组件，以及其他类型的组件。采用组件技术，将辰工光纤声波数据(DAS)解释软件V1.0的数据处理、绘制图形等组件进行集成形成软件

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.
