摘要

基于提高水力能量的利用效率可有效提高钻速的认识，提出了自激振荡式旋转冲击钻井方法。采用大涡模拟的方法分析了自激振荡式旋转冲击钻井工具水力元件的工作机制。采用正交试验方案设计法，对水力元件的结构参数进行了数值模拟优化，并据优化结果研制了自激振荡式旋转冲击钻井工具。现场试验结果显示，优化后的自激振荡式旋转冲击钻井工具的提速效果明显优于优化前，表明所采用的分析和优化方法正确可行。研究结果为自激振荡式旋转冲击钻井技术的发展提供了依据。

Abstract

Self-oscillating rotary percussion drilling method which based on the knowledge of utilization efficiency of the hydraulic power can improve ROP is proposed, the core of the method is self-oscillating rotary impact drilling tool. Modulation mechanism of the self-oscillating hydraulic components was analyzed by large eddy simulation analysis. Using the orthogonal design, self-oscillation hydraulic components were optimized according to large eddy simulation analysis. Based on this, the self-excited oscillation rotary percussion drilling tool is developed. The field test results showed that the effect was better than the old tool, which indicated that the method of optimization self-excited oscillation hydraulic components is correct and feasible. This method provides a theoretical basis which can promote and accelerate the application of this tool, also provides a basis for the study of a related engineering field. The research has the theory and application value.
