1. No matter what the situation well drilling rig operated under insurance regulations, when someone is working on the mast section, under the mast other staff are not allowed to stay. 2. In the event vile weather (rain, snow, ice, or more than five years of night wind) Xinjiang rig manufacturer, not allowed to work on the mast, hydraulic filters. At the same time, do not permit the use of artificial lighting in the mast. 3. Do not use wire rope split shares. 4. landing drill, severely curb touch the rope. 5. In addition to elevating drilling rig, drill pipe endures, open wellhead prohibited. 6. In order to avoid drilling or pumping tube wells outside swinging from the well when pulled, the hook must be applied by 15 ~ 20mm diameter steel bars made of hook. 7. cleaned Henan rig when pumping tube manufacturers, should be applied firmly robust rope looped, set in the lower end of the pump cylinder, which is spilled, CSM. 8. Use the pulley casing promotion or landing when and machinery at the salvage work, all workers should be separated from the drilling. 9. When the casing is pulled out with a crane, in order to prevent the sleeve off, the necessary fixed to each other in the way. 10. In the case of the next stop light (night time), well drilling rig work should be stopped. This time when the well is still drilling, the drill should be vigilant taken out from the well. Submersible drilling rig causing sticking reason submersible drilling rig usually pay attention to maintenance and lubrication of the machine can reduce the incidence of failure, but will focus on maintenance, although a corresponding decrease after a mechanical failure, but still there will be some failures, DTH Sometimes sticking rig failures occur, then the general cause of the failure, what does one, drill bits broken wing;? 2, new for large diameter drill bits than the original; 3, displacement or drill in drilling machine hole deflection; 4, when the rock wall or orifice falling rocks or encounter a major fissures, caverns; 5, in case of mud with stone dust terrain difficult to discharge; 6, negligent operation, stop drilling a long time No blowing rock powder, also did not mention the drill, so that the impact is to be buried rock powder; approach: on the strength of the current drill head, the broken wing has basically put an end, once the special cases rig manufacturers, the diameter of the aperture can be used for some almost the same seamless pipe built with butter, asphalt and other things Hebei rig manufacturers, and pipe connections into the bottom of the hole, the hole at the end of the broken wing to take out fishing before the first hole bottom blowing rock powder. Drill mention more serious situation is not up, fit to go, the impact does not ring, this time only plus torque or aids to help enhance that drill rotation, then you want the edge to the gas, while lifting the drill, until the fault lifted up. Re-drilling, to be a little pressure, then gradually increase the propulsive force, until the normal working pressure.
