Drilling Rigs by Features
Drilling rigs can be divided into core drilling rigs, water well drilling rigs, mechanical top drive drilling rigs, etc., according to their functions.
Core drilling rigs can fully preserve the lithology of the formation and have a high core recovery rate.
The water well drilling rig can drill to a depth of 50~500 meters and is suitable for a wide range of formations.
Mechanical top drive drilling rig can drive the drill pipe to rotate, without releasing the drill pipe, and can drill continuously.
The fully hydraulic core drill has a high coring rate and can achieve stepless speed regulation.
Exploration core drilling rigs can achieve hole depths of 50 to 3,000 meters and are suitable for different rock formations.
Hydraulic deep well drilling rigs have the advantages of strong power, precise control, and adaptability to complex formations.
Diamond core drilling rig is suitable for super-hard rock formations, hydraulic speed regulation, and protection of core structure.
Reverse circulation drilling rigs are mainly used for large-diameter deep hole drilling and are suitable for mineral exploration, water well construction, pile foundation engineering, etc.
Drilling Rigs by Depth
Drilling rigs can be divided into down-the-hole drills, medium-deep hole drills, and deep hole drills according to the drilling depth.
Shallow Hole Drilling RigThe down-the-hole drill has a simple structure, strong mobility and fast drilling speed.
Medium Depth Drilling RigThe medium-deep hole drilling rig is equipped with a feeding mechanism and a pressure stabilizing system, and a top drive device is optional.
Deep Hole Drilling RigThe deep hole drilling rig is equipped with a high-power power system and an automatic pipe laying device.
Drilling Rig Drill Pipe
The drill rods produced by the company are made of conventional materials DZ40, 45# steel, hard rock materials R780/DZ50 alloy steel, etc., depending on the working conditions. They adopt a hollow seamless design and support sampling without lifting the drill.
Drilling Rig Bits
There are many kinds of drill bits for drilling rigs, including carbide drill bits suitable for soil, shale, and medium-hard sandstone, diamond drill bits suitable for granite and quartzite, and toothed roller cutter bits.
Selection Criteria
It is necessary to clarify whether the construction geology is soil, sand, gravel or rock, so as to select the appropriate drill bit.
According to the drilling depth, how much drill rod should be matched.
According to the hole size, match the diameter of the drill bit.
Company Advantage
Pailien has high-end drilling technology and R&D capabilities. Key components are made of high-strength materials and can adapt to complex and extreme working conditions. The equipment meets international safety and environmental standards.
Core Drilling Rig Construction Scene
Core drilling rigs are mainly used in mineral resource exploration, engineering geological surveys, hydrogeological surveys, and geological science research.
In the chromite exploration in South Africa, the project used a PLE-1600 fully hydraulic drilling rig equipped with a rope coring system. The construction team operated in accordance with the specifications and achieved a core recovery rate of 95%, achieving integrity and efficiency in coring.
China’s Qinghai copper mine exploration project uses the PLE-1600 exploration core drilling rig, which is used for the Mesozoic ultrabasic rock formations and is equipped with a diamond drill bit to ensure a mechanical drilling speed of ≥1.2m/h. The core samples are analyzed by ICP-MS at the Natural Resources Testing Center.

After-Sales Service
As a professional drilling rig manufacturer, we can provide fast technical support and guidance services, a professional engineer team is online all day, regular equipment inspection and maintenance services, technical guidance on improving core recovery rate, basic operation specification training, equipment maintenance training, special formation drilling training, spare parts service life tracking management, and lifelong technical support guarantee.
Our company has core technologies with independent intellectual property rights, intelligent and automated automatic deviation correction, and remote monitoring systems; it can cope with complex geological rock formations, and its modular design can adapt to a variety of working conditions. The company has various patent certificates, quality inspection certificates, CE certificates, etc. At the same time, it provides integrated services such as equipment selection, construction training, and maintenance optimization according to customer needs.
The drilling rig can be used in a variety of geological conditions. According to the analysis of practical conditions, it is currently mainly suitable for the following geological conditions: hard base (granite, tuff, etc.), loose and broken strata (sand and gravel layers, fault zones), and soft soil strata (clay, silt, etc.).
Core drilling rigs are mainly powered by internal combustion engines (diesel engines) and equipped with diesel generator sets to adapt to outdoor environments without power grids. The drilling rig’s drill arm, thruster, rock drill and other actuators all use hydraulic oil as the power medium.
The selection of the appropriate drilling rig type can be based on the following aspects: drilling depth and hole diameter, hardness adaptability of the rock formation, power and energy consumption, project construction period requirements, complexity of the terrain, etc.
