摘要

为了充分发挥PDC钻头高效破岩的技术优势,进一步提高其在低渗透地层的机械钻速,研究并设计了双级双速钻井工具。采用数值模拟方法建立了双级双速钻井时的井底岩石物理模型,分析了井底岩石应力分布状态及双级双速钻井的破岩和提速机理;介绍了双级双速钻井工具的常见结构,指出了其技术优势;基于已有研究成果,并结合现场实际需要,从排量、输出扭矩与转速、钻进工具长度等方面进行优化设计,设计出了适用于φ215.9,φ241.3和φ311.1 mm井眼的双级双速钻井工具。设计的双级双速钻井工具在胜利油田3口井进行了现场试验,试验结果表明,双级双速钻井工具使用时钻压、泵压及工具性能稳定,机械钻速比邻井平均提高80.37%,总体效果显著。研究认为,设计的双级双速钻井工具综合性能好,在低渗透地层钻进时能够提高机械钻速,具有推广应用价值。
        In order to fully exploit the technical advantages of PDC bit in rock breaking, and to further improve its ROP in low permeability formation drilling, a two-stage and two-speed drilling tool was studied and designed. A numerical simulation method was used to establish the bottom hole petrophysical model during the two-stage and twospeed drilling, stress field distribution and rock breaking/speed-up mechanisms of two-stage and two-speed drilling were analyzed. The common structure of two-stage and two-speed drilling tool and its technical advantages were presented. Based on the research results and field site requirements, the two-stage two-speed drilling tools for φ215.9,φ241.3 and φ311.1 mm diameter borehole were optimally designed considering flow rate, output torque and rotary speed, drilling tool length, etc.. The tool was tested in 3 wells of Shengli Oilfield and it showed that the WOB, pumping pressure and tool performance are stable, and the ROP is 80.37% higher than that of the offset wells with normal tools.The designed two-stage and two-speed drilling tool presents a good comprehensive performance and can be used to improve ROP in low permeability formation drilling with good application prospective.
