Technical Problems To Be Considered In The Selection Of DTH Drilling Rigs
Choosing the right type of down-the-hole drilling rig can effectively improve work efficiency, reduce cost and consumption, and speed up the progress of the project. The selection of down-the-hole drilling rigs should be considered technically:
(1) Reliability. This is one of the important factors to evaluate the technical performance of the down-the-hole drilling rig. It is mainly determined by the technical parameters such as the capability, accuracy, strength and durability of the DTH Drilling Rig. According to the construction characteristics of the down-the-hole drilling rig, we generally adopt the idea of “big horse trolley” to select the drilling machine to ensure the reliability of the downhole drilling rig under complicated working conditions.
(2) Maintainability. During the life cycle of the downhole drilling rig, inspection, maintenance and repair and modification are the main contents in the maintenance of the downhole drilling rig. Therefore, the maintenance of the drilling rig should be fully considered when selecting the downhole drilling rig, that is, the inspection and maintenance of the drilling rig. Repair is very convenient, very simple, and the interchangeability of the parts is very good, which will reduce the maintenance cost and improve the construction efficiency.
(3) Compatibility. Each component of the down-the-hole drilling rig is relatively independent and self-contained. It is compatible with a variety of working conditions, a variety of different products and components, and has good matching with existing models. It can reduce costs and better adapt. Market changes, after simple deployment, can complete a variety of production and construction needs. If some components are common to common components on the market, priority should be given to the selection of downhole drilling rigs to reduce the cost. As the DTH Well Drilling Rig develops toward large-scale and automation, the possibility of manual control of the down-the-hole drilling rig is becoming less and less, so that the down-the-hole drilling rig has higher self-controllability, which is also a measure of the performance of the down-the-hole drilling rig. Basic indicators.
