Submersible drilling rig

Submersible drilling rig is easy to handle a common fault, drill pipe rupture: generally due to the drill hole wall friction at longer working time conditions, so that the drill pipe wall thickness, strength. Or drill pipe has bending load stress concentration is also easy to cause fracture. Treatment: when grafting drill should always be carefully checked and found that wear and drill pipe bending, discontinue use. Second, the impact is an exception: the impact of failure of the primary abnormality is not sound, because there are at four: 1, cutting sheet break; 2, drill head and tail broken, debris from entering the cylinder stuck hammer; 3, exhaust holes are blocked by rock powder; 4, when drilling down, the hole too much water, too much exhaust resistance, the impact is not easy to start. Treatment: found impactor does not ring, press the first four kinds of reasons for inspection, examination method is to enhance the impact is some distance, reduce exhaust resistance, blowing a portion of the water, and then slowly into the hole at the end, if this method When not, it is judged the first three reasons, need to be cleaned or replaced impactor remove parts. Submersible drilling rig three, sticking: Sticking Failure: 1, the new-for-drill head than the original large diameter drill bits; 2, drill bits broken wing; 3, drilling machine displacement or deflection in the drill hole; 4 , rock fall when opening or hole stone wall face big cracks or caves; 5, in case of mud with stone of the heart is not easy slag; 6, long time stop drilling, no blowing rock slag, nor Lift the drill, so that the impact is to be buried rock slag; 7 In complex formations can make drilling machine in normal sticking. Treatment: Once the drill head broken wing case, the available period similar to the diameter of the aperture seamless tube built with butter, asphalt and other things connected with the drill pipe into the hole at the end, the bottom of the hole to get out of the broken wing. Salvage before the first blow hole at the end of rock powder. Shock does not ring, this time only plus torque or aids to help improve that drill rotation, then to the side to the gas, while lifting the drill, until the fault is removed so far. Re-drill, first a little to pressure, then gradually increase the thrust until the normal operating pressure. Fourth, the drill head debris out column: Available strong hair blowing method, alloy column does not move when the big blow, also dampened handle drill head with broken wing approach.
