智能录井技术研究进展及发展展望

Research Progress and Development Prospect of Intelligent Surface Logging Technology

  • 摘要: 录井具有样品条件及制样工序复杂、采集项目多而离散、人工经验依赖性强且人均产值低等特点,亟需加强智能化转型,但相比于其他石油工程技术,智能录井技术进展缓慢,且局限于应用层面。为此,从智能钻井的进展与成效入手,分析了国内外智能钻井在硬件系统、控制系统、应用系统方面的进展与差距;然后,从地质录井、工程录井、智慧平台3个方面分析了智能录井的主要技术进展,包括“数据+”驱动和视觉驱动的岩性识别、流体识别、井下与地面风险识别及预警等。通过对比智能钻井与智能录井的现状,提出智能录井应强化井下智能录井、智能录井机器人等硬件系统及多场数字孪生、多元采集智能控制、多模态录井大模型、智能解释评价等软件系统的研发。同时强调,既要高度重视,又要理性看待智能录井的发展,要在回顾评价、横向对比的基础上,做好战略定位与研发流程优化,实现进度追赶与作用发挥。这些分析与观点,对推动智能录井实现良性、快速发展具有指导意义。

     

    Abstract: Surface logging has the characteristics of complex sample conditions and sample preparation process, numerous and discrete collection items, strong dependence on hands-on experience, and low per capita output. It is urgent to strengthen intelligentialization transformation. However, compared with other petroleum engineering technologies, intelligent surface logging is making slow advancement and facing application limits. Therefore, the progress and gap of hardware systems, control systems, and application systems of intelligent drilling in China and abroad were analyzed from the progress and achievement of intelligent drilling. Then, the main technical progress of intelligent surface logging was analyzed in terms of geological surface logging, engineering surface logging, and intelligent platform, covering “data +” driven and visually driven lithology identification, fluid identification, and downhole and surface risk identification and early alarming. Based on the comparison between intelligent drilling and intelligent surface logging, it was suggested that the research and development of hardware systems such as downhole intelligent surface logging, and intelligent surface logging robots, as well as software systems such as multi-field digital twins, multi-acquisition intelligent control, multimode large model of surface logging, and intelligent interpretation and evaluation should be strengthened. At the same time, it was emphasized that we should attach great importance to and rationally look at the development of intelligent surface logging and determine strategic positioning and process optimization on the basis of retrospective evaluation and horizontal comparison, so as to catch up with the progress and engagement. These analyses and viewpoints have guiding significance in promoting the benign and rapid development of intelligent surface logging.
