Segmented fracturing of horizontal well is the core technology of shale gas reservoir development. The conventional method at home and abroad is segmented fracturing of compound bridge plug. In order to produce logging in the later stage, coiled tubing must be used to drill and grind all bridge plugs. The soluble fracturing ball needs to withstand the high temperature of nearly 150°C and the pressure difference of more than 70 MPa, and the stress area is very small when it is pressed. Therefore, the thermal stability against short circuit and the mechanical strength of the fracturing ball is required.
