Fracturing method capable of promoting balanced crack initiation and extension of each cluster of cracks and application

The invention discloses a fracturing method capable of promoting balanced crack initiation and extension of all clusters of cracks and application. The fracturing method comprises the following steps: (1) descending a pipe string comprising an ejector, a centralizer, a perforating gun and a bridge plug to a to-be-fractured section of a horizontal well, and sequentially carrying out bridge plug seat sealing, first cluster perforation, pre-fracturing of the first cluster perforation and bridge plug unsealing; the pipe string is lifted up to the position of a second cluster in the section to be fractured, and then bridge plug setting, second cluster perforation, pre-fracturing of the second cluster perforation and bridge plug deblocking are conducted; repeating the above procedures until the pre-fracturing of the multi-cluster perforations in the to-be-fractured section is completed; (2) taking out the pipe string, pumping the pipe string into a bridge plug again, setting and releasing, and fracturing multiple c
