Rotary drilling opportunities to how to solve the problem
20 Mar,2018
Rotary drilling rig in the use of a lot of unexpected small problems, if as a novice certainly can not be handy to treat, it also needs long-term accumulation and practice. After all, there are many possible problems, such as falling objects, hole collapse, hole body deviation and other problems. Let's look at all possible problems and solutions of small rotary drilling rig manufacturers. When falling objects, they should be fished quickly with fishing forks, hooks, rope sleeves and other tools. If falling objects have been buried by sediment, mud and sand should be removed according to the above-mentioned items, make the fishing tool touch the falling body before fishing. In any case, it is strictly prohibited for construction personnel to enter the casing
How to do the sediment of rotary drilling rig
Rotary drilling rig may have some sediment at the bottom of the hole during the hole forming process. This is inevitable and can be said to be a defect of rotary drilling rig. Then why does it have sediment at the bottom of the hole? The main reason is that its construction technology is different. The rotary drilling rig method uses non-circulating mud drilling, so the drilling slag cannot be carried to the ground through the circulation of mud to settle down. Our small rotary drilling rig manufacturers can form a rotary drilling rig for continuous slag discharge. There are several main factors for sediment occurrence. Residue between the bucket teeth of the rotary excavator and the bottom cover of the drilling bucket; The bucket teeth of the small rotary drilling rig are sparsely placed, and the drilling slag flowing between the teeth is not
