Recently, many friends mentioned the collocation of drill pipe and drilling rig. Some friends think that as long as the drill pipe and drilling rig can be connected, some friends think that there is a certain rule between the two. So in the end between the drill pipe and the rig how to match the use of it? Xiao Bian first talk about personal point of view. On the issue of selecting drill pipes, the editor has to say that the drill pipe products produced by Qianjiang Machinery are mainly used in drilling, mining, and anchoring in coal mines, mines, construction and water conservancy projects, railways, highways, tunnels and bridges. In coal mines, it is mainly used for coal mine water exploration, gas exploration, coal direction exploration, coal thickness and coal seam water injection. and each
Recently, many friends mentioned the collocation of drill pipe and drilling rig. Some friends think that as long as the drill pipe and drilling rig can be connected, some friends think that there is a certain rule between the two. So in the end between the drill pipe and the rig how to match the use of it? Xiao Bian first talk about personal point of view.
On the issue of selecting drill pipes, the editor has to say that the drill pipe products produced by Qianjiang Machinery are mainly used in drilling, mining, and anchoring in coal mines, mines, construction and water conservancy projects, railways, highways, tunnels and bridges. In coal mines, it is mainly used for coal mine water exploration, gas exploration, coal direction exploration, coal thickness and coal seam water injection. Moreover, the diameter and application fields of various drill pipes are different. Therefore, Xiao Bian suggested that all friends should "check their seats" when choosing drill pipes ". Then the question arises, how to "take the right seat?
Let's take geological drill pipe, geological spiral drill pipe, high-efficiency spiral drill pipe and triangular drill pipe as examples,
How to choose the drill pipe and drilling rig is the best match?
Geological drill pipe is mainly used for water exploration, gas exploration and coal exploration;
The geological spiral drill pipe is mainly suitable for deep hole drilling construction with medium-hard geological conditions and has the function of slag discharge;
The high-efficiency spiral drill pipe is suitable for the drilling construction of water exploration and gas exploration under the geological conditions of coal seam and near coal seam, and has the characteristics of light weight, rapid connection and fast slag discharge speed;
Triangular drill pipe is the first choice for deep hole drilling in soft geological and soft coal seams. In the scope of use of various products, it can also be seen that all kinds of drill pipes have their own unique advantages. Only when we clearly understand the characteristics and application scope of each product can we do it in the process of selecting products.
Of course, in the process of selecting products, product characteristics are considered on the one hand, and on the other hand, it is also the most critical aspect, that is, the torque of the drill pipe and the drilling rig must be matched, otherwise it will break. Then the question arises again, how to choose the match?
We know that the torque of the drilling rig is fixed, so how does the torque value of the drill pipe come from those factors?
Xiao Bian also learned after consulting senior technology that the factors affecting the torque value of drill pipe are composed of the following aspects. Now learn to sell it now:
Drill pipe torque value mainly by the drill pipe body specifications, material and drill pipe joint form and production process changes produce different performance conclusions. Among them, the change value is due to different materials and processes. The drilling depth of the drill pipe is related to the torque of the drill pipe, but it is not absolutely determined by the torque of the drill pipe. The drilling depth should be determined according to different geological conditions and the selected drill pipe and bit type.
In this way, the torque of the drill pipe and the drilling rig is selected well, and then the corresponding drill pipe is selected according to the geological conditions of the operation, and the matching drill bit can be selected for construction. Of course, these are all theoretical data, and specific problems can be analyzed in the construction process.
