Drilling platforms move oil and gas from one location to another. They are called well pads and they are located on land or offshore, depending on where the well is being drilled. A good platform is a combination of structures and equipment used to drill a well, prepare it for production, and produce oil or gas.

Drilling rigs are giant machines that drill holes to extract oil and gas. The rig usually consists of a large diameter rock drill bit located on top of a long drill column that is lowered into the borehole and rotated to drill the hole. The drill column is made of a long continuous string of long steel or continuous tubing. Thus, here are some of the benefits for the drill rig manufacturer.

It can reduce the cost of oil-related products - the rig can help by reducing the cost of drilling, the cost of cleaning and maintaining the well, the cost of delivering groundwater, and the cost of delivering oil and gas to the surface. It can reduce net costs by reducing the cost of delivering oil and gas to the surface. For example, when drilling a well, the cost of running and maintaining the rig is high. As oil prices rise, drilling rigs can significantly reduce these costs.
It creates local jobs - oil rig manufacturers, service companies, and workers for these companies all benefit from oil rig manufacturers. The oil rig manufacturer benefits from the service company, which in turn benefits by providing services to the oil rig manufacturer. Workers benefit by finding jobs and being part of the community. It creates jobs at the local level. The rigs make many components, but the most important is the large metal pipe that is attached to form the drill column, which is then lowered into the well.

It helps development - young people understand the value of oil rigs and they are likely to be in the same class as oil rig workers. In addition, oil rig workers and other oil rig workers become more aware of the nature of oil rig work and are more likely to become more able to earn a living. It helps to develop local communities, as rig owners and service companies have local communities as their customers. It helps to develop the local economy.
It provides more domestic self-sufficiency - the oil and gas industry is one of the largest and best-organised industries in the world. The industry is at the forefront of technology and is able to offer new and innovative drill bits and columns as well as new technologies for oil and gas extraction. This provides the owner with an independent supply of oil and gas and also helps him to reduce his energy costs.

Drilling equipment suppliers have a significant impact on communities and economies. In countries where jobs are scarce, the jobs created by the oil industry are an important opportunity for people to be employed. It is also an important opportunity for young people to get an education.
As a result, the relatively high incomes of oil rig manufacturers and the relatively high incomes of oil rig service companies are a benefit to both the communities their companies serve and the workers they employ.
Drilling is an important part of mining mines. The equipment used is mainly the top hammer drilling rig or DTH drilling rig. These two are suitable for different mining operations, and the wrong use will cause huge losses. If you want to know the difference between these two rigs, keep reading.

Top Hammer Drilling Rig
The impact force of the top hammer drilling generated by the piston of the pump in the hydraulic drilling rig is transmitted to the drill bit through the shank joint and the drill rod, which is the most different from the down-the-hole drill. At the same time, the percussion system drives the drilling system to rotate. When the stress wave reaches the drill bit, the energy is transferred to the rock in the form of penetration by the drill bit. The combination of these functions can drill holes in hard rock.
However, top hammer drilling is usually used for the maximum diameter of 127mm, and the depth of the hole is less than 20M, which has high efficiency.
In Top Hammer Drilling the hammer produces a percussive force on the drill rods or tubes, which is transmitted to the drill bit. The feed device is usually attached with a hinged boom to a mobile unit. The percussive system strikes the drill rod, for example 2,000-5,000 strikes per minute, and the rotation speed can be, for example, 60-200 rounds per minute. Together these elements make it possible to drill holes in the hard rock. The excess material (cuttings) is flushed up from the bottom of the hole by means of pressurized air or water. Top hammer drills are primarily used in mining, construction and quarrying of rock material. Top hammer drilling, combined with the “drill and blast” method, makes the whole excavation process extremely efficient.
DTH Drilling Rig
The down-the-hole drill uses compressed air to drive the hammer behind the drill bit through the drill rod. The piston directly hits the drill bit, and the hammer cylinder provides a straight and stable guide for the drill bit. This keeps the effects of energy from being lost in the joints and allows deeper percussion drilling.
In addition, the impact force acts on the rock at the bottom of the hole, which is more effective and straighter than other drilling operations.

DPH drilling is more suitable for large holes in hard rock drilling, especially for rocks with a hardness of more than 200Mpa. However, for rocks below 200 MPa, not only energy will be wasted, but also the drilling efficiency will be low, which will cause serious wear on the drill bit. This is because when the hammer's piston strikes, the soft rock cannot fully absorb the impact, which severely reduces the efficiency of drilling and slagging.
In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the fluid (air, water or drilling mud) used to actuate the hammer and flush the cuttings. The drill pipes are added to the drill string successively behind the hammer as the hole gets deeper.
The hammer is fully fluid actuated. It is composed of two mobile parts: a valve, controlling the flow and a piston that strikes on an impact surface directly linked to the bit. The hammer body gives straight and stable guidance of the drill bit.
JK410 Crawler Mounted Pneumatic Tophammer Drill Rig
Top Hammer Drilling Rig
ㆍThe most suitable for hole diameter between 25–127 mm.
ㆍGenerally, the hole depth is less than 25 meters.
ㆍAdapt to a stable and uniform hard rock.
ㆍThe slag flushing medium is compressed air or water.

JK650 All In One DTH Drilling Rig
Down the Hole (DTH) Drilling Rig
ㆍThe most suitable hole diameter is 100–254 mm, in special applications can be up to 2M And the minimum can be around 50 mm as well.
ㆍTheoretically drilling depth is limited by back pressure only (can be up to several kilometers).
ㆍAdapt to hard rock and rock formation conditions (compared to top hammer).
ㆍMainly use pressurized air for slag flushing, and sometimes air foam for special application.
ㆍHighly efficient in hard rock drilling.
In summary, each drilling rig has its own advantages. When choosing the equipment, you can first look at the actual situation of your project, and decide which type of rig to choose according to the rock formations, geological formations, and working environment of the construction site.
