Abstract
A mud pulse generation system based on two-way communication includes a turbine stator having at least two stator openings (35) each with a preset opening angle; a turbine rotor, having a sidewall provided with at least one wide blade and at least one narrow blade spaced from each other through several openings; a power generation module driven by rotation of the turbine rotor for supplying power; and a master device configured to control relative time when the wide blade or the narrow blade passes through the stator openings by controlling a controllable load of the power generation module based on uplink information, generate an uplink pulse signal with variable time intervals at the stator openings, and monitor and decode three-phase AC voltage signal output by the power generation module to obtain downlink information. This system is able to generate high-frequency pressure fluctuation pulse without requiring external power supply.
