The utility model provides an it is wireless along with boring instrument turbogenerator water conservancy diversion structure in oil drilling, including stator, stator stay tube, drive urceolus and rotor, the stator cover is established on the stator stay tube and both fixed connection, the stator stay tube is connected with the drive urceolus, the mounting of rotors is on the drive urceolus, drive urceolus and stator stay tube are connected one end and are equipped with upper bearing sleeve, and the other end is equipped with lower bearing sleeve, the stator surface is equipped with a plurality of blades along the even setting of circumference, is the blade 0 with the axis contained angle 40, form the guiding gutter between two adjacent blades. Through increase the blade on the stator,by the stator and the rotor mating reaction of different angles for the velocity of flow that mud erodees on the rotor changes, thereby it changes to drive the rotor speed, can reduce the rotational speed and at the excessive speed to the wearing and tearing of turbogenerator, can guarantee to send sufficient power again and supply power for the MWD instrument.
