Description
[technical field]
The present invention relates to oil exploration equipment technical fields, and in particular to impulse generator in a kind of wireless drilling inclinometers
Energy conservation, safety give method for electrically.
[background technique]
In geological drilling, oil drilling, measurement-while-drilling system is continuous detection wellbore trace, well track is carried out and
When adjust essential measuring tool.Especially directional well, in horizontal well engineering, the application of measurement-while-drilling system is more wide
It is general.In measurement-while-drilling system, wireless drilling inclinometers are one of main components.
Wireless drilling inclinometers are mainly made of battery, inserting tube and impulse generator several major.Wherein battery is to pulse
The electromagnetic valve current of generator carries out spacing movement with trigger generator.In the impulse generator course of work, between battery
Every release current to solenoid valve, the magnitude of current that battery disposably discharges every time is larger, be easy to cause the damage of battery.
[summary of the invention]
To solve the above problems, can prevent battery from disposably discharging super-high-current the purpose of the present invention is to provide a kind of
It measures, the energy conservation of impulse generator, safety give method for electrically in the wireless drilling inclinometers to prevent battery damage.
To achieve the above object, the technical scheme adopted by the invention is as follows: the section of impulse generator in wireless drilling inclinometers
Energy, safety give method for electrically, capacitor are arranged between battery and the connection circuit of solenoid valve, according to the workplace of impulse generator
The capacity of the capacitor used needed for the time, setting, the capacity of capacitor is not less than needed for impulse generator in the unit time
Whole electricity summations the speed of battery release electricity, the electricity that battery discharges in the unit time are set according to the capacity of capacitor
Measure the capacity that summation is equal to capacitor.
Compared with prior art, the invention has the following beneficial effects: pulse generations in above-mentioned wireless drilling inclinometers
The energy conservation of device, safety give method for electrically to enable battery slowly to carry out the release of electric current by the way of capacitor is arranged,
By the electricity storage and boosting of capacitor, feeding gives impulse generator and works, to prevent battery damage.
[specific embodiment]
Below by specific embodiment to the energy conservation of impulse generator, safety in wireless drilling inclinometers of the present invention
It is described in further detail to method for electrically.
The energy conservation of impulse generator, safety give method for electrically in wireless drilling inclinometers, in the connection electricity of battery and solenoid valve
Capacitor is set between road, according to the operation range time of impulse generator, the capacity of the capacitor used needed for setting, capacitor
The capacity of device is not less than whole electricity summations needed for impulse generator in the unit time, according to the capacity of capacitor, setting electricity
Pond discharges the speed of electricity, and the electricity summation that battery discharges in the unit time is equal to the capacity of capacitor.
For example: if the operation range of impulse generator is 0.1 second, every work once needs the electricity of 0.5C, setting
Unit time be one minute, then in the unit time total electricity needed for impulse generator be 300C, then select capacity be not less than
The capacitor of 300C sets speed of the battery to capacitor release electricity, is 5C/ seconds, that is, exists then according to the capacity of capacitor
In one minute, battery can be full of capacitor, and with the continuous work of capacitor, battery also constantly discharges electricity to capacitor, from
And ensure that has electricity in capacitor.
The energy conservation of impulse generator, safety give method for electrically in above-mentioned wireless drilling inclinometers, use setting capacitor
Mode, enable battery slowly to carry out the release of electric current, stored by the electricity of capacitor and pulse hair is given in boosting, feeding
Raw device works, to prevent battery damage.
The principles and effects of the invention, and the implementation that part uses only is illustrated in the above embodiments
Example, and is not intended to limit the present invention；It should be pointed out that for those of ordinary skill in the art, not departing from wound of the present invention
Under the premise of making design, various modifications and improvements can be made, and these are all within the scope of protection of the present invention.
