摘要
提高钻井速度不仅是提高我国油气效益开发及深地勘探等方面的重要技术手段,同时对保障国家能源安全意义重大.冲击破岩钻井技术在国内外油田现场应用并获得了良好的提速效果,持续开展此类技术攻关有望攻克当下我国深地高温高压硬岩地层进尺低、提速难的技术痛点.介绍和分析了轴向冲击、扭力冲击和轴-扭耦合冲击辅助钻头破岩钻进技术方面的实践及发展动态.结合冲击破岩钻井技术现状,阐明了冲击辅助钻头破岩力学原理是冲击破岩钻井提速技术的关键问题,综述了国内外研究学者在冲击辅助钻头破岩物理实验、理论模型和数值模拟等研究方法上取得的科学进展.针对冲击破岩钻井提速技术的发展提出了相关建议,即加强在材料结构优化设计、智能化控制、多元技术融合和井场应用优化等方面的研究力度,为我国能源高效开发做出贡献.
Abstract
Enhancing the rate of penetration(ROP)is crucial for optimizing the efficiency of oil and gas development and deep explo-ration in China and ensuring national energy security.The percussion rock-breaking drilling technology has been applied in oil fields at home and abroad,resulting in significant improvements in ROP.Further research efforts are expected to address the technical chal-lenges of low drilling footage and limited ROP enhancements encountered during deep exploration of hard rock formations with high temperature and pressure.This paper presents and analyzes the practice and development trends of the drill bit percussion rock-break-ing drilling technology assisted by axial percussion,torsional percussion,and axial-torsional coupled percussion.It illustrates that the percussion-assisted drill bit rock-breaking mechanism is the core of percussion rock-breaking ROP improvement technology.This paper also reviews the scientific advancements made by domestic and overseas research scholars in physical experiments,theoretical modeling,and numerical simulation of percussion-assisted drill bit rock-breaking.In addition,it offers relevant proposals for the de-velopment of percussion rock-breaking ROP improvement technology,i.e.advancing research on material structure optimization de-sign,intelligent control,integration of multiple technologies,and optimization of well applications.This is expected to provide valuable insights for enhancing the drilling efficiency in energy development of our country.
