Technical field
The present invention relates to a kind of low-power consumption continuous-wave generator, it is adaptable to measurement while drilling, the downhole data of well logging during are wirelessly transferred
System, it is possible to effectively reduce motor side load torque and power supply power consumption, improve continuous-wave generator drive system dynamic
Energy.
Background technology
Along with to land oil gas, deep-sea oil gas, shale gas, underground heat, the continuous increase of combustible ice equal energy source demand, survey as it
Visiting most important or the only resource of exploitation, drilling technology is also evolving, and since the eighties in 20th century, has entered with information
Change, intelligence turn to the automated drilling stage of feature, need to obtain the most in real time down-hole information as much as possible the most urgently,
Down-hole information transmission technology is made to become the key technology realizing automated drilling.
Down-hole information transmission means mainly has drilling fluid pulse method, sonic method, Electromagnetic Wave Method etc..Wherein drilling fluid pulse method application
At most, robustness more preferable, it includes positive pulse method, negative pulse method and continuous wave method.Positive and negative impulse method is widely used at present,
But its transfer rate is relatively low, typically smaller than 3bps, it is increasingly difficult to meet quickly, obtain in real time the automated drilling of down-hole information
Demand.Continuous wave method has that robustness is good, transfer rate advantages of higher is it is considered to be a kind of well with broad prospect of application
Lower information data transmission technology, at present, foreign study is more, but only Schlumberger has commercially produced product, as
PowerPulse, Slimpulse, its continuous wave signal speed produced is up to 16bps；Domestic relevant research is still in theory
Exploratory stage.
1964, Mobil Oil Corporation proposed continuous wave signal transmission method first, and the method is pacified in the drill collar be positioned at down-hole
Dress choke valve also allows part or all of mud to flow through, and by continuously adjusting choke valve openings of sizes, periodically blocks in pit shaft
Flowing, forms the pressure wave of Phase Continuation in the mud in drilling rod, be called for short continuous wave.Drilling fluid flowing is blocked by changing
Frequency or phase place carry down-hole information to be transmitted, obtain the pressure wave signal of frequency modulation(PFM) or phase-modulation.Detection should on the ground
Pressure wave signal, then demodulates this signal and obtains down-hole information.
In continuous wave data are transmitted, continuous-wave generator is nucleus equipment.At high pressure, high flow capacity, the down-hole ring such as work continuously
Under border, being affected by high speed drilling fluid, the load torque of continuous-wave generator rotation system is relatively big, and fluctuation is very big, because merit
Consume proportional with torque, rotating speed, therefore need driving motor and the power supply of relatively high power, such as the continuous wave of 16bps to be produced
Driving motor and the down-hole power of more than hundreds of watts may be needed.Additionally, continuous wave signal transfer rate to be improved, need to increase
The rotating speed of rotation system, can cause bigger power consumption demand.The load torque of continuous-wave generator rotation system is big so that continuously
Wave producer, when down-hole services, can only use the turbogenerator of high-output power to power, and high-power turbo electromotor cost,
Research and development difficulty is big, and the biggest torque ripple brings the biggest difficulty to the control of continuous-wave generator.Continuous-wave generator to be reduced
Power demands, need reduce motor side load torque.The load torque of continuous-wave generator is cyclic fluctuation, mainly
The friction torque caused by waterpower torque, high pressure sealing and bearing suffered by rotation system forms, and can be decomposed into DC component and friendship
Variation is measured.The existing research about continuous-wave generator load torque, concentrates on and inquires into the change of waterpower torque suffered by rotation system
Rule, there is no the method report effectively reducing motor side load torque, it is impossible to motor side load torque is big, power supply power consumption is big in solution
Etc. problem.
