Abstract

Summary A high-frequency axial-torsional composite percussion drilling tool is designed to enhance the drilling efficiency by delivering high-frequency axial and torsional impact loads directly to the drill bit. The impact performance and influencing factors of the tool are analyzed via the large eddy simulation method, and a scaled-down experiment on the pulse nozzle structure is conducted. The analysis reveals that after design optimization, the tool achieves high-frequency axial and torsional impacts of 421 and 284 Hz, respectively, at an inlet flow rate of 30 kg/s. Additionally, the unilateral amplitudes of the axial and torsional impact loads reach 1511 N and 19.3 N·m, respectively, with a pressure drop of 2.998 MPa. Furthermore, the similarity degree between the parameters derived from the experiment and numerical analysis is close to or exceeds 70%, demonstrating the reliability and precision of the numerical analysis results. Overall, this study sets a baseline for high-frequency impact technology, paving the way for further advancements in drilling efficiency.

高频轴扭复合冲击钻井工具的研制与优化

为了提高钻井效率，设计了一种高频轴向和扭转复合冲击钻井工具，将高频轴向和扭转冲击载荷直接传递到钻头上。通过大涡模拟方法分析了刀具的冲击性能及其影响因素，并对脉冲喷管结构进行了缩小实验。分析表明，优化设计后，在进口流量为30 kg/s的情况下，该工具分别实现了421 Hz和284 Hz的高频轴向和扭转冲击。轴向和扭转冲击载荷的单侧幅值分别达到1511 N和19.3 N·m，压降为2.998 MPa。实验参数与数值分析参数的相似度接近或超过70%，表明了数值分析结果的可靠性和精度。总的来说，该研究为高频冲击技术奠定了基础，为进一步提高钻井效率铺平了道路。
