Advances in vibration impactors for drilling acceleration

As the vibration impactor was identified as the one of direct and effective means of reducing the cost and increasing efficiency, it was widely recognized and valued in oil-gas drilling area. In this article, through the latest research progress about the several kinds of vibration impactor such as the axial impactor, the torsional impactor and the compound impactor were introduced in detailed, it can be seen 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, by the means of reasonable use and conversion of mud hydraulic energy. According to the field application, the rate of penetration can be improved and the drilling cycle can be shortened in different degree through using the vibration impactor.
