Treatment Method For Buried Drilling Of Wheeled Rotary Drilling Rig

Sometimes during the operation of a wheeled rotary drilling rig, the phenomenon of burying the drill may occur, and many operators do not know what to do. In fact, as long as they know the cause, it will be much easier to deal with it.
Physical picture of wheeled rotary drilling rig
Burial drilling is caused by hole collapse or sediment burying the drilling bucket. Therefore, the mud quality should be increased to enhance the buoyancy of the mud. The sediment at the bottom of the hole should be flushed by a water pump, and the sediment should be cleaned by circulating the mud. A straight cylinder drill body can be used, which has no difference in performance from a conical one and can effectively reduce the possibility of burying the rotary drilling rig. The sediment should be blown up by an air pump, and the self-priming pump should suck the sediment outside the hole. After processing the sediment, the wheeled rotary drilling rig should not rush to lift the drilling bucket. Instead, it should rotate left and right and transmit pressure slightly downwards. If the sediment at the bottom of the rotary drilling rig cannot be lifted and rotated after treatment, a crane with an empty space should be used to lift a long heavy object and impact the vibrating drilling bucket at the bottom of the hole. If the drilling bucket cannot be lifted after handling the sediment, directional blasting can be used to place explosives inside the bucket for blasting. If there are mud quality issues or the drilling time is too long, Resulting in excessive sediment at the bottom of the hole, light load during hole cleaning, and easy drilling depth, leading to excessive drilling depth per bucket and burying of the drill. Mud was modulated according to geological and groundwater conditions, and the mud viscosity was used to protect the wall, while the specific gravity pressure supported the hole wall. The mud sand content exceeded the standard, and the wheeled rotary drilling rig malfunctioned without fuel, causing the drilling bucket to stay in the hole for too long, and sediment buried the drilling bucket.
Finally, the editor suggests that everyone should not panic when encountering problems while driving and operating a wheeled rotary drilling rig. It is important to identify the problem before resolving it.
