| Abstract: | Structure analysis of the inner bit in gravel drilling tool is made in the paper in order to make sure that it meets the requirement of high boring speed of seismic exploration in unconsolidated formation and gravel strata. The force that stressing the inner bit is stressed is complex and analysis of intensity of the inner bit is made by ANSYS project analysis software base on the finite element theory, and the method of improving the punishing stress on the face of the inner bit pedestal is proposed. |
