| description | Due to some drawbacks of conventional drilling methods and drilling tools, the application of
hydraulic hammers with a fluidic amplifier have been extensively popularized since its emergence in recent
years. However, the performance life of a fluidic amplifier is still unsatisfactory in oil and gas wells drilling,
especially the heavy wear or erosion of the fluidic amplifier leads to the reduction of service life time of
hydraulic hammers, which is derived from the incision of drilling muds with high speed and pressure. In order
to investigate the influence of drilling muds, such as particle size, solid content and jet velocity, on the antierosion
property of a fluidic amplifier, several groups of drilling muds with different performance parameters
have been utilized to numerical simulation on basis of Computational Fluid Dynamics (CFD). Simulation results
have shown that the jet nozzle of fluidic amplifiers is primarily abraded, afterwards are the lateral plates and the
wedge of the fluidic amplifier, which shows extraordinary agreement with the actual cases of fluidic amplifier in
drilling process. It can be concluded that particle size, solid content and jet velocity have a great influence on
the anti-erosion property of a fluidic amplifier, and the erosion rate linearly varies with the particle size of
drilling muds, nevertheless exponentially varies with solid content and jet velocity of drilling muds. As to
improve the service life time of a fluidic amplifier, the mud purification system or low solid clay-free mud
system is suggested in the operation of directional well drilling |
