Drilling techniques for borehole drilling vary from basic digging with manual tools to costly equipment. To give an idea to the readers who have no background to the drilling method, the most frequently used boreholes are described briefly below. See what industrial pipe suppliers have to say about borehole drilling.
Protection and Applications of Borehole Methods
Cable Tool Drilling
The oldest method of drilling is cable tool drilling. It is also known as percussion drilling. This means that a solid steel drilling string tools are suspended from a wire section can be lifted and decrease to hit the ground. This process causes the formation to be cut, fractured or powdered.
There are three primary operations in cable or percussion drilling:
• Drill the hole through the effect of the driller bit by smashing the rock or clay
• The cuts with the bailer should be eliminated as sequences build up in the gap
• Force the boron to fall into the hole while the drilling is going on.
Because the initial costs and the easy use of the equipment are relatively low, costs per drilled unit are inexpensive as well. But the technique is slow, and when the increased labor costs are taken into account, the advantage of the drilling technique is generally low compared to the fast-moving borehole drilling techniques.
Type of Drilling Techniques
Air Drilling
The rotating air is one of the methods used for drilling troughs in joint formations, like sandstones or shells that support themselves.
The cuttings produced by this process are purged by air circulating from the compressor and fed down through the drilling pipe.
Down-hole Hammer Method
Drilling with the bottom hammer is the easiest way to crack hard rock. This technique is mainly applied for hard rock and water drilling from hard rock aquifers can be established.Yet for drilling loose, unconsolidated materials are not usable.
Mud Drilling
The drilling agent used as a means of diffusion in rotary mud (water mixes, bentonite clays, polymers and additives). Boiling dust is pumped through a drilling pipe and out by dozers in the bit in the rotary mud method.
Such methods are useful for soft, deep and pressure boring drilling operations.
Drilling of Sonic
Sonic drilling is one of Borehole Drilling methods' latest techniques. This technique is fairly continuous, and geological samples without the use of boiling fluids or other possible pollutants are collected continuously.
The technique is best suited to unconsolidated trainings, but its ability to depth is restricted by modern technology.
