Well drilling tool capable of producing axial impact vibration

The utility model relates to the technical field of matching devices for petroleum and natural gas well drilling and provides a well drilling tool capable of producing axial impact vibration. The well drilling tool capable of producing the axial impact vibration comprises an upper sleeve, wherein a blocking disc is fixedly arranged on the inner side of the lower end of the upper sleeve, an anvil shaft is arranged in the upper sleeve in a sliding mode and provided with a hollow central flowing channel extending along the axial direction, a lower connecting section of the anvil shaft penetrates the blocking disc and is in threaded connection with a lower connector, and an impact device capable of producing axial impact on the anvil shaft is sleeved on an upper shaft section of the anvil shaft in a sliding mode. For avoiding 'dragging-pressing' and 'stick slip' phenomena existing in the drilling process of a high-frictional-resistance well section, a characteristic that the vibration can influence friction coeff
