Abstract

The invention discloses a novel turbodrill capable of achieving accurate positioning of a stator and a rotor. The novel turbodrill is applied to the fields of petroleum drilling, mining, geological drilling and the like and solves the problem that the hydraulic performance of turbine sections is low when the turbodrill works. According to the technical scheme, the turbine stator is fixedly installed on a turbine shaft through a screw and a fastening nut, and the inner wall of a shell and the outer wall of each stage of a stator sleeve are provided with two symmetric key grooves to position the turbine stator in a flat key mode; the turbine shaft and a rotor sleeve are both machined to be regular octagon structures which are mutually matched; a thrust bearing set is installed on the middle-back section of the turbine shaft; a planetary gear reducer is arranged in a lower shell. According to the novel turbodrill, by means of the two methods that the turbine rotor and the turbine stator are fixed in the circumferential direction, it is guaranteed that the stator and the rotor cannot relatively rotate separately and precise circumferential positioning of the stator and the rotor can be achieved, therefore, the hydraulic performance of the turbodrill is improved, and meanwhile the cost is lowered.

Description

technical field [0001] The invention relates to a novel turbine drilling tool which can realize the precise positioning of the stator and rotor, which is used in the fields of petroleum drilling, mining, geological drilling and the like. Background technique [0002] With the development of deep wells and ultra-deep wells in my country's deep earth exploration and oil and gas exploration, turbodrilling tools now have very good development prospects. The rotation of the turbodrill is caused by the conversion of kinetic energy formed by the velocity of the fluid into mechanical energy. During the flow of the medium channel of the entire turbodrill, the most important link is the turbine section, and the turbine section is also a key part that affects the hydraulic performance of the turbodrill. The turbine section is the key link that directly affects the conversion of the kinetic energy of the liquid into mechanical energy in the entire medium channel, because it is the only...
