岩屑远程识别技术研究与应用

Remote identification technology for cuttings

长城录井自主研发的远程录井平台应用无线宽带组网技术将岩屑图像快速传到基地,可登录网络并操控岩屑图像采集系统进行实时拍摄,实现基地专家决策和岩屑远程识别,充分发挥少数基地专家的技术优势,避免地质录井现场复杂岩性识别及关键层位卡取等重要作业环节发生错误。基地专家利用远程录井平台,通过观察现场岩屑图像和操控现场图像采集仪进行拍摄的方式,对岩屑图像进行分析、描述、定名,实现了岩屑远程识别和指导层位卡取。岩屑识别定名由现场向基地专家的转变,提高了岩屑识别的准确性和及时性,避免层位卡取和岩屑识别错误的发生,既有利于管理层决策,也提高了录井作业效率。

Remote mud logging platform,which was self-developed by Greatwall Mud Logging Company,uses wireless broadband networking technology to quickly transmit cutting images to the base,logs on to the network and controls cutting image acquisition system to take photos in real-time,thus making full use of the technical superiorities of the base experts and avoiding errors to occur at the important Geo-Logging operation parts of on-site complex lithology identification and key horizon determination.Experts at the base can use remote mud logging platform to analyze,describe and name cutting images through observation of on-site cutting images and control of on-site image acquisition instrument to shoot the scenes,realizing a remote cutting identification and guidance of horizon determination.The change of identifying and naming cutting from the wellsite to base experts improved the accuracy and timeliness of cutting identification,avoided the errors in horizon determination and cutting identification,was both in favor of management decision-making and improvement of the efficiency of mud logging operations.
