自激振荡旋转冲击钻进工艺可提高碎岩效率，提升机械钻速。在冀中地区北部试验井中进行了应用试验。试验井段钻孔直径215.9 mm，钻具组合为PDC钻头+ZJXC-178型自激振荡冲击工具，分试钻井段和后续井段两个井段进行了现场应用试验。通过对同井、邻井的扭矩、钻头使用情况、机械钻速及岩屑等分析对比，自激振荡旋转冲击钻进工艺显著提升了钻井速度，实现了高达73.4%的提速效果，并且单只钻头的进尺量也得到了48.2%的提升。验证了该工艺在提升钻井效率方面的有效性，在保证钻头破岩切削力的同时，有效减小了扭矩的突变，显著抑制了钻头粘滑振动现象，从而实现提速的同时保护钻头。
The self-excited vibration rotary percussion drilling technology can improve the rock breaking efficiency and the ROP.The application test in a test well located in the northern part of the Jizhong region were presented.The drilling diameter of the test well section is 215.9mm， and the BHA is PDC bit+ZJXC-178 self-excited vibration impact tool. The field application tests are carried out in two well sections， the test drilling section and the subsequent well section. Through a meticulous analysis and comparison of torque， bit usage， ROP and cuttings in the same well and adjacent well， the self-excited vibration rotary percussion drilling technology significantly improved the drilling speed， achieved the speed increase effect of up to 73.4%， and the footage of a single bit also increased by 48.2%.The effectiveness of this technology in improving drilling efficiency is verified. While ensuring the rock breaking cutting force of the bit， the sudden change of torque is effectively reduced， and the stick slip vibration of the bit is significantly inhibited， so as to achieve speed increase and protect the bit at the same time.
