| 摘 要： | 为了解决油气钻井水平井硬地层可钻性差、钻速慢的问题，同时减小水平井段滑动钻进中出现托压的现象，提高钻井效率，通过对工具原理进行分析，对结构及参数进行改进，研制出了适于水平井段的射流式冲击器，并在台架试验的基础上，进一步优化了性能参数、钻具组合及旋冲钻井参数，并开展了水平井段现场试验应用。现场试验结果表明，在水平井段采用射流式冲击器提速效果显著，具有深入研究的价值。但冲击器在水平井段失效问题影响了其提速效果，本文对其存在的问题进行了理论及试验分析并提出了改进方案。

| Abstract: | In order to solve the problems of poor drillability and slow ROP, reduce the friction drag in slide drilling of the horizontal section, and improve drilling efficiency in drilling horizontal wells in hard formation for oil and gas, a fluid powered efflux hammer was developed for horizontal drilling through the analysis of the tool working principle and the improvement of the structure and parameters. On the basis of bench tests, the performance parameters , drilling tool assembly and rotary percussive drilling parameters were further optimized, and the field tests for horizontal drilling were carried out. The results of field tests showed that the fluid powered efflux hammer has a remarkable effect in increasing the ROP over the horizontal well section, so it is worth further research. However , the failure of the tool in the horizontal section affects its effect in improving the ROP. In this paper, the problems of the tool are analyzed theoretically and experimentally, with the improvement plan put forward. |
