Advances in vibration impactors for drilling acceleration

Abstract:

As one of the direct and effective means of increasing ROP and efficiency， the vibration impactor is widely recognized and valued in the oil-gas drilling area. This article describes in detail the latest research progress on several kinds of vibration impactors such as the axial impactor， the torsional impactor and the compound impactor， and illustrates that the vibration impactor can effectively enhance the energy of breaking rock， improve the bit condition of breaking rock， and reduce the resistance of breaking rock through reasonable use and conversion of mud hydraulic energy. Field application has shown that the vibration impactor can improve the rate of penetration， and shorten the drilling period.
