Tiltedly instrument etc., wherein wireless drilling inclinometers is because it is easy to use, efficiency is high and is gradually widely used.Wireless drilling inclinometers
Signal transmission form mainly have mud transmission, electromagnetic transmission, a sonic transmissions, and be transmitted as main with mud.Thus mud arteries and veins
Rush one of device just most critical component becoming wireless drilling inclinometers, directly contact mud due to it, accept the high-speed punching of mud
Brush and erosion effect, be consumable accessory and expendable part in wireless drilling inclinometers.Currently used more general mud pulse generator just
Mostly structure is complicated, slurry channel winding complex, and fault rate is high, O&M inconvenience, particularly can not Solve on site, usually
Overhaul for some minor issues producer to be transported back or base, add logistics and time cost, raised drilling cost.
Mud pulse generator is generally sent instruction by inserting tube, power supply be that electric magnet is powered, by electro-magnet switch servo
Valve, switchs main valve by the amplification of mud, thus produces pressure pulse, the pressure transducer on the drill string of ground in drill string
The signal of telecommunication that upper generation is corresponding with pressure pulse.What in wireless drilling inclinometers works, consumption electricity was most is exactly electric magnet,
And it is limited for driving the capacity of power supply, and price is high.Currently used more general mud pulse generator just, is profit mostly
Closing servo valve with energy-accumulating elements such as springs, the pretension that the energy-accumulating elements such as servo valve spring to be overcome are bigger is opened in electric magnet energising
Power and consume limited electric energy in a large number, add the consumption of power supply and the number of times of round trip, significantly raised drilling cost,
Reduce production efficiency, add the potential safety hazard of drillng operation.
