Embodiment Construction
[0030] The present invention is introduced below by accompanying drawing.
[0031] figure 1 The structure of an auxiliary downhole drilling tool 100 according to the present invention is shown. Such as figure 1 As shown, the auxiliary downhole drilling tool 100 includes an impact energy generator 110 . The impact energy generator 110 is mainly used to convert the energy of the drilling fluid to generate axial impact energy. An impact energy distributor 120 is also provided at the lower end of the impact energy generator 110. The impact energy distributor 120 is mainly used to redistribute the axial impact energy generated by the impact energy generator 110, thereby forming a and the composite impact energy of the circumferential impact energy. Through the impact energy generator 110 and the impact energy distributor 120, the downhole auxiliary drilling tool 100 can provide the drill bit with high-frequency and variable impact force in multiple directions, effectively impro...
