Efficient-fracturing carbon dioxide fracturing device

The invention discloses an efficient-fracturing carbon dioxide fracturing device which comprises an energy release head. A shear plate is fixedly connected in the energy release head, the bottom end of the energy release head is fixedly connected with a main pipe, and seal gaskets are arranged between the energy release head and the main pipe and fixedly connected to the top and the bottom of theshear plate respectively. An inflation valve is fixedly connected to the bottom end of the main pipe, a heating tube is fixedly connected in the main pipe, a gas pipe internally penetrates the main pipe, and two sides of the gas pipe are communicated with energy release through pipes respectively. The efficient-fracturing carbon dioxide fracturing device has the advantages that the problem that anexisting carbon dioxide fracturing device normally adopts single-structure retaining plates for retaining in fracturing is solved, the problem of low fracturing effects of a traditional method is avoided, the utilization rate
