The invention relates to a guide device for pushing a fracturing pipe into a drilled hole during coal bed gas phase fracturing. The guide device is mainly composed of a guider composed of a cone and a bottom end cylinder, and the cone and the bottom end cylinder are connected in an arc transition mode and integrated. Before the first fracturing pipe enters the drilled hole, the guider is screwed down at the headmost end of the fracturing pipe, and the bottom face circle of the cone and the front end of the fracturing pipe are made to coincide and then pushed into the fracturing drilled hole together. The scrapping function on the wall of the drilled hole by the gas phase fracturing pipe can be eliminated, resistance exerted on the fracturing pipe in the advancing process is reduced to a certain degree, the construction difficulty in engineering practice is effectively lowered, and the construction progress is accelerated.
