Water Well Drill Rig and drilling technology

Water Well Drilling Rigs Supplier shared that drilling is the use of mechanical equipment to drill a certain amount of attempted holes through the formation. It can be divided into cable drilling technology and rotary drilling technology according to rock breaking mode and drilling tool type.

In geological exploration and geological engineering, it is beneficial for drilling equipment to drill underground. For cylindrical holes with smaller diameter and larger depth, they are called boreholes. Different drill straight and drill depth are designed according to drilling purpose. For example, drilling for oil, gas, and ground water has larger bore sizes. General boreholes used for geophysical logging such as coring are small.

The main functions of drilling are:

1. Obtain underground physical data, and obtain core, cuttings, oil, water and natural gas from the bottom of the well.

2. As a geophysical logging channel, it can obtain the data of various geophysical fields in rock layers, such as for underground ordnance test.

3. As an artificial channel, it can be used to observe minerals, hydrology and geological structures in the strata.

4. Comprehensive application, integration of exploration and collection, and exploitation of underground resources.

Water Well Drilling Rigs Supplier

Water Well Drill Rig Supplier China points that according to the purpose, drilling is generally divided into geological survey drilling, geological exploration drilling, Wells, engineering geological drilling, geothermal drilling, oil drilling and so on.

Cable drilling, also known as impact drilling, generally with wire rope to the cable drilling bit to the bottom of the well, by the power drive beam mechanism, so that the beam to do up and down movement, and drive the wire rope and drill impact up and down, so as to break the rock. Drilling equipment is simple, low cost, does not pollute the oil layer, but it is slow, low efficiency, shallow drilling, can not adapt to complex strata and deep well requirements, gradually replaced by rotary drilling
