The operation of the well drilling rig should be carried out with care to avoid accidents in operation.Next xiaobian will tell you about the construction process should pay attention to.
The operation of the well drilling rig should be carried out with care to avoid accidents in operation.Next xiaobian will tell you about the construction process should pay attention to.
Rig operators need to master basic knowledge of rig operation and maintenance, as well as some experience in troubleshooting.Will not be able to communicate with more experienced teachers.Safety inspection shall be carried out on the drilling rig for loading water well. All parts of the drilling rig shall be complete and there shall be no leakage of electricity in the cables.When entering the construction site, the drill tower shall be fixed, the drill area shall be larger than the drill seat, and there shall be enough safety space around.
The well drill before drilling
1. Before drilling, the drilling rig shall be constructed in strict accordance with the hole position, azimuth, Angle and hole depth, etc., and the rig operator shall not make any unauthorized changes.Do not comply with the provisions of the implementation of the risk of unpredictable accidents, remember.When installing drill pipe, check the drill pipe to ensure that the drill pipe is not blocked, not bent, not cracked, not worn wire mouth, unqualified counterfeit drill pipe is strictly prohibited to use.
2. When drilling with clean water, water supply shall not be allowed before drilling, and drilling can only be conducted with pressure after water return, and sufficient flow shall be ensured. Xi 'an well drilling rig maintenance shall not be allowed to drill dry holes, while hebei well drilling rig maintenance shall be allowed.
Drilling in a well rig
1. To accurately measure the distance in the drilling process, it is necessary to measure the drill pipe every 10 meters of drilling or changing the drill tool, verify the hole depth and make relevant records.Look at the gearbox, shaft sleeve, vertical shaft gear and so on whether there is overtemperature phenomenon, whether there is abnormal sound, when the problem should be immediately shut down to find the cause of timely treatment, do not stay put the problem is not solved, so that the cumulative mechanical damage is very fast, and high maintenance costs.
2, when using clean water drilling, drilling must not supply water before the return of water to pressure drilling.And make sure there's enough traffic.Yin heng service engineers remind you that when there is too much rock powder in the hole, increase the amount of water to extend the pump time, etc.
3, in the drilling process to accurately measure the distance, changsha well drilling rig maintenance, generally every 10 meters or change the drill pipe must be measured once, in order to verify the hole depth.Gearbox, shaft sleeve, horizontal shaft gear and so on whether there is excess temperature phenomenon, whether there is abnormal sound, found the problem should immediately stop, find the cause, timely treatment.
