摘要
冲击器对旋冲钻井技术的实施起着至关重要的作用。随着计算流体动力学(CFD)技术的发展,CFD也逐渐应用到冲击器的设计和模拟当中。优选了适合液动射流式冲击器性能模拟的CFD软件,建立了计算模型并进行了计算分析,同时利用先进的粒子图像测速(PIV)技术对射流元件的内部流场进行了观测,对CFD模型进行了验证。最后指出,随着计算机技术的不断发展以及CAD/CAE、CFD和PIV技术的有机融合,冲击器虚拟样机设计和模拟技术将会得到进一步的发展和提高,这也是冲击器设计和模拟技术的一个重要发展方向。
The hydro-efflux hammer plays a very important role on rotary percussion drilling technology. With the development of CFD, it is used in the design and simulation of hydro-efflux hammer. This paper selected the suitable CFD software for hydro-efflux hammer performance simulation and built the model for calculation analysis. At the same time, the PIV technology was used to observe the element flow field to validate the calculated results using proposed model. At last, this paper pointed out that the design of hydro-efflux hammer dummy model machine will be developed and improved with development and combination of the CAD/CAE, CFD, PIV, etc. It is also an important development direction for the design and simulation of hydro-efflux hammer technology.
