Pulse generator for well logging

The invention discloses a pulse generator for well logging, and relates to the technical field of well logging while drilling. The pulse generator comprises a drill collar, as well as a first diverter, an electronic frame, a second diverter, a mud pulse generator and a third diverter which are arranged in the drill collar; a first annulus through which mud flows is formed between the electronic frame and the drill collar; a second annulus through which the mud flows is formed between the mud pulse generator and the drill collar; the first diverter is provided with a first channel through whichthe mud flows; the first channel communicates with the first annulus; the second diverter is provided with a second channel through which the mud flows; the second channel communicates with the firstannulus and the second annulus; the third diverter is provided with a third channel through which the mud flows; and the third channel communicates with the second annulus. The pulse generator does not change a flow path of t
