Beschreibung
Zusammenfassung:	The invention discloses a pulse generator that is installed in an inner pore for hanging a pup joint. The pulse generator includes: a pulse generating part used for generating negative pulse; a pressure balancing part that is arranged above the pulse generating part and balances the pressure of hydraulic oil in the pulse generator and the pressure of annular mud; and a pressure measuring part that is arranged below the pulse generating part and used for respectively detecting the pressure of mud in a drill column and the pressure of the hydraulic oil. The pulse generator detects the pressure of the annular mud and the mud in the drill column through the pressure balancing part and the pressure measuring part, thus improving the safety of a bored well.
