The pressure resistance performance of borehole pressure pillows with different thicknesses under working conditions was studied by using the method of combining experiment and simulation. The designed pressure pillow can bear the internal pressure of about 28 MPa and the external pressure of about 17 MPa under the condition of applying the inclusion body. Rupture areas concentrated in the weld area. Based on the theory of elastic-plastic simulation, finite element analysis software ABAQUS was used to simulate the borehole pressure pillow under the condition of the working stress distribution, analyze the inclusion spacing of 45.6 mm and 70 mm case of stress distribution. The purpose of this paper is to determine the type of the operation condition of the working conditions of borehole pressure pillow to ensure the pressure pillow sensitivity.
