智能化钻井背景下,传统的司钻调控钻进参数的钻井模式已经无法满足钻进参数自适应调控的需求,而数字孪生技术具有实时同步、真实映射和高保真度的特性,因而构建钻进参数自适应调控数字孪生系统,与智能钻井设备、智能终端相结合,可实现钻机自主送钻和自主定向。为此,在介绍钻进参数自适应调控技术架构及其工艺流程的基础上,设计了基于数字孪生技术的钻进参数自适应调控系统架构,包括物理钻井平台、虚拟钻井平台、钻井孪生数据、服务应用层和通信连接层5个要素;并从数字孪生系统的构建、演化及更新等3个方面阐述了钻进参数自适应调控数字孪生系统的运行机制,分析了关键理论技术需求。研究表明,钻进参数自适应调控数字孪生系统能够实现钻进参数自适应调控技术和智能钻机、智能设备的深度融合,推动数字孪生技术在钻井工程中的应用,对于实现智能化钻井有重要作用。

Under the background of intelligent drilling,the traditional drilling mode in which the drilling parameters are controlled by the driller fails to meet the needs of adaptive control of drilling parameters.Because the digital twin technology has the characteristics of real-time synchronization,faithful mapping,and high fidelity,a digital twin-based adaptive control system for drilling parameters was constructed,which combined with intelligent drilling equipment and intelligent terminal,so as to realize autonomous bit feed and autonomous orientation of the drilling rig.Therefore,the technical architecture of adaptive control of drilling parameters and its process flow was introduced,and the architecture of a digital twin-based adaptive control system for drilling parameters was designed,including five components:physical drilling platform,virtual drilling platform,drilling twin data,service application layer,and communication connection layer.The operational mechanism of the digital twin-based adaptive control system for drilling parameters was discussed from three aspects:the construction,evolution,and updates of the digital twin system.Furthermore,the key theoretical and technical requirements were analyzed.The research shows that the digital twin-based adaptive control system for drilling parameters integrates adaptive control technology for drilling parameters with intelligent drilling rigs and equipment,promoting the application of digital twin technology in drilling engineering and significantly contributing to the realization of intelligent drilling.
