Description
Technical field
It the utility model is related to a kind of mud-pulse generating means；Belong to wellbore measurement while drilling and control device field.
Background technology
The exploration and development of petroleum gas carries out in extremely rugged environment, and as well depth is continuously increased,
Geology and the situation of bottom are more complicated, and the working environment of downhole well tool is further severe, and difficulty of construction also further increases,
Therefore measurement while drilling is carried out to the situation of underground, and the requirement for being in time transmitted measurement data is also stringenter.Surveyed with boring
The technical method of well and measurement while drilling is during drilling well, while measuring oil/gas well physical parameter and other parameters, is incited somebody to action
Underground signal is quickly and accurately transmitted on ground, not only ensure that the quality of well bore, but also improves drilling efficiency.
But as China exploits complex hydrocarbon field, the data that needs transmit in operation are more and more, to passing
The requirement of transmission quality also higher, the defects of causing positive pulse signal transmission and undersuing transmission, are prominent all the more, and research and development are continuous
Wave generator is extremely urgent.In order to break the external technical monopoly to continuous wave signnal generator, China's oil row is lifted
The status of industry in the world, it is independent develop stablize, efficiently, reliable continuous pulse signal generator has become must
Right trend.
The content of the invention
The purpose of this utility model is that：The mud-pulse hair that a kind of reliability is high, rational in infrastructure, transmission rate is high is provided
Generating apparatus.
The technical solution of the utility model is：
A kind of mud-pulse generating means, including drill collar, protective casing, motor, fair water cone and fixes sleeve；Its feature exists
In：Motor is provided with by protective casing in drill collar；The termination of protective casing is provided with stator by blocking ring, below stator
Fixes sleeve is provided with drill collar, stator is in close contact with fixes sleeve and connects；Transmission shaft one end of motor extends to stator
In centre bore, rotor is provided with fixes sleeve, rotor is threadedly coupled with transmission shaft, is provided with and is led on the rotor in fixes sleeve
Flow cap, fair water cone and rotor key connection.
The rotor is in ⊥ shaped cylindrical bodies, and rotor block is arranged at intervals with the lower circumference of rotor.
The stator is taper cylindrical body, and shape corresponding with rotor block is provided with stator gear on the lower circumference of stator
Block.
Rotor block is slided with stator block and is fitted and connected.
Sealing ring is provided between the stator and transmission shaft.
The beneficial effects of the utility model are：
When the mud-pulse generating means works, by the rotation of rotor relative stator, make the overcurrent between rotor and stator
Continuous cycles change occurs for area, and mud pressure diminishes with becoming larger for circulation area in tubing string, with diminishing for circulation area
And become larger；Continuously rotating makes mud stream circulation area also continuously change, so that being produced in tubing string continuous
Mud-pressure pulses, the pulse generating unit is rational in infrastructure, reliability is high, transmission rate is high, especially suitable for well logging and
Measurement while drilling pulse generation uses.
