Summary:A pressure pulse generator for a downhole drilling tool is provided. The pressure pulse generator includes a stator with an orifice through which a stream of fluid passes, and a rotor intended to rotate opposite the stator to allow the flow of more or less liquid exiting the orifice of the stator. The rotor is equipped with an orifice, and the two orifices present a communicating area for the passage of the stream of fluid. The rotor is capable of passing fluid therethrough. A turbine with blades rotatable in response to fluid flow through the rotor may also be provided. The turbine is operatively connected to the rotor via a drive shaft. The fluid flow through the rotor may be used to rotate the turbine and provide power usable in the downhole tool. Se proporciona un generador de impulsos de presion para una herramienta generador de impulsos orificio a traves del rotor pretendido para de perforacion de fondo del pozo. El de presion incluye un estator con un cual pasa una corriente de fluido, y un girar opuesto al estator para permitir el flujo de mas o menos liquido que sale del orificio del estator. El rotor esta equipado con un orificio, y los dos orificios presentan una area de comunicacion para el pasaje de la corriente de fluido. El rotor es capaz de pasar fluido a traves del mismo. Una turbina con paletas giratorias en respuesta al flujo de fluido a traves del rotor tambien se puede proporcionar. La turbina esta conectada operativamente al rotor a traves de una flecha de impulsion. El flujo de fluido a traves del rotor se puede utilizar para: hacer girar la turbina y proporcionar energia utilizable en la herramienta en el fondo del pozo.
