Liquid carbon dioxide phase changing and directional blasting fracturing device

The invention discloses a liquid carbon dioxide phase changing and directional blasting fracturing device. The device comprises a liquid storage pipe and a release pipe fixedly connected to the front end of the liquid storage pipe, the back end of the liquid storage pipe is fixedly connected with an orientation pipe, a power supply and an electronic compass are fixed in the orientation pipe and electrically connected, and the electronic compass is further electrically connected with a displayer located outside the orientation pipe. According to the device, the back end of the liquid storage pipe is fixedly connected with the orientation pipe, the electronic compass is arranged in the orientation pipe and connected with the external displayer, therefore, parameters such as the track, the inclination angle and the rotating angle of the release pipe in a drill hole are monitored in real time, the position of the release pipe and the direction of a release hole/gap are conveniently regulated, then directional fracturing is conducted, and improvement of the liquid carbon dioxide phase changing and directional blasting fracturing efficiency is promoted.
