What should be paid attention to when the grooved drill pipe is applied
The grooved drill pipe adopts the product structure design of double helical structure or multi-head helical type with large pitch and small compound lead, which improves the drilling and slag removal characteristics of the drill pipe. It is widely used in many engineering projects, and it is also the choice of many professional technicians. Today, the editor will tell you what to pay attention to when applying grooved drill pipe?
Grooved drill pipe
1. Its application needs to be within the rated drilling distance of the drilling rig equipment, and the matching drill pipe should be selected according to the performance parameters, model specifications and specifications of the drilling distance.
2. It is made of a special geological environment exploration tube for mining geology and its matching terminal friction welding, so it has very good follow-up and high tensile strength, and can be used in common exploration and gas release. use. When constructing in hard rock layer, coal rock or other unique natural environment, it is necessary to clarify the drilling thickness according to the physical properties and basic parameters of the specific material of the drill pipe.
3. When it is used with the drill bit supporting facilities, the drill bit should generally exceed the inner diameter of the drill pipe. During the whole process of drilling, special attention should be paid to the conditions of the drilling rig equipment and drill pipe. If there are frequent occurrences of stuck drilling, sudden death, etc., the drilling should be stopped immediately or drilled back slowly to ensure that the drill pipe is not bent and deformed into a flat shape.
4. When the grooved drill pipe is drilled, it should be manually and slowly tightened to ensure a close fit (external thread type). It is not possible to use the drilling rig equipment to drill directly to avoid damage to the drill pipe.
The above is the whole content of "What should be paid attention to in the application of grooved drill pipe?", I hope you can understand.
