Explanation of drilling terms, explanation of drilling, what is the explanation of drilling

Drilling refers to the operation of drilling and sampling with machinery and tools to determine the geological conditions of the formation, which is an important technical means in geological exploration. A drill rig is used to drill down from the surface to create cylindrical holes in the formation to identify and divide the formation. Cores, ore samples and soil samples can be obtained from different depths in the borehole for analysis and research, which can be used to determine the physical and mechanical properties and indicators of rock and soil layers and provide design needs.

Drilling is the use of drilling rig equipment to drill holes from the surface to the ground, so as to achieve the required task of engineering construction.

Engineering. From the purpose of drilling, it can be divided into: geological drilling, hydrological water well drilling, engineering survey drilling, oil drilling and so on.

1.Geological drilling: the operation of obtaining cores and ore samples from different depths in the borehole for analysis and research, identifying and identifying the ore body or dividing the strata, and judging the geological conditions of the strata.

Usually the cost of drilling in geological prospecting accounts for at least 40% or more. The diameter of the boreholes is small (46-91 mm) and the depth varies from tens to thousands of meters, depending on the type of mineral.

2.Hydrological well drilling: cementing wells into holes when drilling to the aquifer (position), so as to meet the problem of drinking water for people and livestock and irrigation of farmland or provide hydrological observations for the geological department.

For hydrogeological drilling, the diameter of the survey hole is less than 150 mm, the diameter of the exploration hole is 150 350 mm, the diameter of the water well is 150 550 mm, and the depth of the hole is more than 300 meters.

3.Geothermal drilling: Drilling is completed, and geothermal resources are exploited and utilized through heat carriers. At present, the drilling depth of the technology can generally reach 3000 to 5000 meters, and the utilization of geothermal resources is relatively good.

High-temperature geothermal fields, Xi'an geothermal fields, and the north are concentrated in Beijing and Tianjin.

4.Engineering survey and drilling: obtain core and soil samples from boreholes for physical properties.

The analysis can be used to determine whether the foundation meets the bearing gravity and stability of the engineering construction. Engineering geological drilling is to survey dam foundations, reservoirs, channels, port projects, and high-rise buildings.

and engineering geology along railways and highways.

5.Petroleum drilling: drilling into holes for direct resource development and utilization, three well-known in China: PetroChina, Sinopec.

Sea Oil. The borehole is generally 915 mm open, the final hole is 216 mm, the hole depth is 1000 7000 meters and above, and the blowout prevention equipment is usually installed at the wellhead.

6.Cultural relics exploration and drilling (drilling): Intuitively and accurately obtain the cultural accumulation data of a certain location, which is less labor-saving and less destructive than excavation, and can understand a large area of underground conditions in a short time.

It is suitable for understanding the distribution range, thickness, shape and layout of large building sites, large tombs and ancient cities.

Drilling or exploration is the use of mechanical engineering techniques of deep drilling to exploit natural resources in the underground or seabed, or to take a live profile of the stratum and extract physical samples to provide experiments to obtain relevant data.

Diamond refers to diamond that has been polished, which is a natural mineral that is the rough of diamonds. To put it simply, diamond is an elemental crystal composed of carbon that is formed under high pressure and high temperature conditions in the deep part of the earth. Beautiful, rare, and a symbol of love and fidelity, diamonds represent eternal love.

The chemical composition of diamonds is carbon, which is the only one in gemstones that is composed of a single element and belongs to the equiaxed crystal system. The presence of impurity elements, the most important of which are N and B, is related to the type and nature of the diamond.

Explain in detail. Ye Shengtao's "Friendship": "When any ore is drilled, it will immediately become very useful." Ke Yan's "Happy Little Poems, Tongtiao, Tongtiao is gone!" "It doesn't look like it's blind and naughty, but why is it secretly drilling? ”

Answer: In geological exploration and building foundation exploration, drilling rigs are used to construct boreholes according to a certain design angle and direction, and core (or core) and cuttings are taken through boreholes or test instruments are lowered into the hole to explore underground rock formations, ore bodies, oil and gas and geothermal engineering. Abbreviated as drilling.

An important part of prospecting engineering. In drilling, the main mechanical method of crushing rock, other physical or chemical methods of crushing rock, is still in the experimental research stage. According to the external force mode of broken rock, it can be divided into percussion drilling, rotary drilling, percussion rotary drilling, vibration drilling and jet drilling. According to whether the core (or core) is taken during drilling, it can be divided into core drilling and non-core drilling; According to the abrasives used in crushing rocks, they are divided into cemented carbide drilling, drill grain drilling and diamond drilling.

Drilling is an important technical means of geological exploration, which is widely used to find and explore various minerals, oil and gas reservoirs, groundwater, geothermal, and provide geological data for water conservancy construction, engineering construction and transportation facilities. Drilling machinery mainly includes drilling rigs, mud pumps, power machines and drill towers. A drilling rig is the most important piece of machinery used to drill holes into the ground.

Mud pump, also known as drilling pump, is a mechanical equipment that transports mud or water and other flushing fluids to boreholes. The drilling tower, also known as the derrick, is a tower erected above the drilling site or well site and cooperates with the drilling rig winch to lift the drilling tool.

The core drilling method is a method that uses a special drilling rig to drill core samples from structural concrete to test the strength of concrete or observe the internal quality of concrete. Due to the local damage it causes to structural concrete, it is a means of on-site inspection of semi-breakage.
