Summary information

The product description

产品参数

In geological exploration and construction foundation exploration, drilling machines are used to drill holes at a certain design Angle and direction, and cores (or ore cores), cuttings or test instruments are taken through the holes to explore underground strata, orebodies, oil and gas, and geothermal energy. Drilling for short.

In drilling, the main application of mechanical methods to break rock, other physical or chemical methods to break rock, is still in the experimental research stage. According to the external force of breaking rock, it can be divided into impact drilling, rotary drilling, impact rotary drilling, vibration drilling and jet drilling, etc. It can be divided into coring drilling and non-coring drilling according to whether or not core is taken during drilling. According to the abrasive used in crushing rock, it is divided into carbide drilling, drilling and diamond drilling.

Drilling machinery mainly includes drilling RIGS, mud pumps, power engines and drill towers. A drill is a mechanical device for drilling into the ground. Mud pump also known as the drilling pump, is to drill mud or water and other flushing fluid mechanical equipment. Drill tower, also known as the derrick, is erected in the drilling field or above the wellsite, with the rig winch to lift the derrick tower.

Main fields:

It is widely used to search for and explore various minerals, underground water and geothermal resources, as well as to investigate dam foundations, reservoirs, channels, port projects, high-rise buildings and engineering geology along railways and highways

Development prospects:

According to the advanced geological science theory, on the basis of the possession of a large number of field geological observation and collection of relevant geological data, the comprehensive geological means and methods such as geological survey, geophysical and geochemical exploration, and drilling pit exploration engineering are adopted to obtain reliable geological and mineral information data. The "green exploration guidelines" issued by the ministry of natural resources clearly pointed out that: to encourage the use of modular, portable, small, high integration of portable drilling construction and supporting equipment; When using mud for drilling operation circulation fluid, non-solid or low-solid environmental protection mud should be adopted to reduce the burden brought to the ecological environment and restore and improve the ecological environment.

Green exploration needs new equipment, new technology, new methods, innovation resources exploration and development mode, improve construction efficiency, reduce the damage to the ecological environment.

Main functions of drilling fluid:

The harsh environment of underground drilling operations facilitates the research and development of drilling fluids, which require the ability to perform a number of key tasks during drilling: suspension, pressure control, rock stability, buoyancy, lubrication, and cooling.
