Why groundwater is concentrated in the oblique core location

Storing water diagonally. The oblique structure is conducive to groundwater recharge, and the water of the two wings is collected in the middle and infiltrates into groundwater, so the well can be drilled in the chute part. Anticline is a good oil and gas storage structure, there are abundant oil and gas resources under the anticline terrain, and the oil fields are widely distributed, so it is necessary to find anticline when looking for oil and gas resources.

The distribution of groundwater is influenced by factors such as topography, hydrogeological conditions and rainfall. The groundwater converges in the oblique core for several reasons:

1.Quality of bedrock: The flow of groundwater is closely related to the permeability of the rock or soil layer. The strata of the inclined core are usually composed of high-quality bedrock, which has good permeability, and groundwater is easy to infiltrate and descend along it, forming a watershed.

2.Surface topography: The slope of the core is located in a relatively low terrain, and when the precipitation infiltrates downward, the groundwater naturally collects into the low area, forming a concentrated water source.

3.Regional precipitation: Complementing the topography, precipitation is one of the main reasons affecting groundwater accumulation. The oblique core usually induces more precipitation behind it, and the water naturally collects in the core to form a body of water, such as surface wells and springs.

4.Hydrogeological conditions, including rock brittleness, joint development, special geological structures in fault zones, etc., often control the movement direction of groundwater.

Faults and joints often form in the oblique core, so groundwater flowing along these "cracks" eventually flows into a single core.

Considering the above factors, the inclined core usually collects and determines the direction of groundwater movement in the basin area, so that the groundwater can be concentrated and replaced in the core, forming a large watershed distribution such as "underground rivers". This is one of the reasons why many centralized urban water sources are located at these confluences of inclined cores.

Groundwater is concentrated in the slanted core for several reasons:

Stratigraphic structure: Dip is a form of geological formation, usually consisting of a convex slope and a concave slope. At the core of the dip, the strata are usually thicker and the rocks are denser, so they can hold more groundwater.

Surface water recharge: The location of the inclined core is usually the area of surface water recharge, such as rainfall in mountainous areas, rivers, lakes, etc., and these water sources will penetrate into the ground to form groundwater.

Groundwater flow: The flow of groundwater is affected by factors such as stratigraphic structure and topography, and the location of the inclined core is usually the low point of groundwater flow, where water molecules naturally gather.

In summary, the concentration of groundwater in the inclined core is due to the combined effect of stratigraphic structure, surface water recharge and groundwater flow.

When groundwater flows in underground rocks, it is controlled by the pores and fissures of the rocks, creating a flow channel. Groundwater storage and accumulation occurs when groundwater encounters different rock layers. In the core of the slope, different types of rock layers are usually stacked on top of each other, forming a rock site with a large water-soil interface, so it is easy to form a zone with abundant groundwater.

At the same time, groundwater that permeates downward along the inclined rock strata will gradually accumulate at the core of the inclined core. The combination of these special geological conditions often leads to the accumulation of groundwater in large quantities at the location of the inclined core.

Groundwater is one of the most important freshwater resources in nature, which has an important impact on the maintenance of ecosystems and human production and life. There are several main reasons why groundwater is concentrated in the oblique core location:

Influence of fault structure: Faults, fissures and other geological structures form a large pressure around the groundwater, and the closer to the fault, the greater the pressure of the groundwater, thus forming an oblique core position.

Lithological influences: Some pores in rocks are relatively stable, and groundwater can easily accumulate in these stable pores to form water layers. The core of the dip is usually composed of relatively good lithology, relatively hard rock masses with more stable pores and more groundwater.

Land cover impacts: The accumulation of groundwater is often affected by land cover. The oblique overlying rocks are often covered by a thicker surface, which can effectively prevent groundwater from being lost through infiltration, etc., resulting in the concentration of groundwater.

Influence of hydrogeological conditions: The geological conditions of the inclined core are often more suitable for groundwater accumulation, for example, these areas contain better water source rocks, water source faults and other conditions, which can effectively promote the accumulation of groundwater.

Based on the above factors, it can be concluded that the core location of the oblique core usually has better groundwater accumulation conditions, which is the result of the combined action of various factors.

Groundwater is concentrated in the oblique core and is formed by a combination of geological and hydrological conditions.

Geological conditions: Dip is a geological structure in the earth's crust, which is the form of inclined or curved strata. Dip is usually caused by crustal movements, and the slope of the strata is large, resulting in the accumulation of groundwater at the core of the dip.

At the core of the dip, the strata are more inclined and there are a large number of aquifers that are capable of storing more groundwater.

Hydrological conditions: The movement of groundwater is affected by hydrological conditions. The location of the inclined core is usually the elevation of groundwater flow, which means that the groundwater source area near the location of the inclined core is closer to the surface water source.

The movement path of groundwater in the formation is usually in the direction of gradual decline in elevation, so groundwater is more likely to accumulate in the core of the slope.

In summary, the main reason for the concentration of groundwater in the inclined core location is the combination of stratigraphic inclination of geological structure and hydrological conditions. These geological and hydrological conditions make the groundwater form a large aquifer at the core of the slope, and the flow path makes the groundwater source area and the surface water source close to each other, so that the groundwater is concentrated in the core of the slope.

The concentration of groundwater in the inclined core is due to a combination of factors. These include:

Permeability of rocks: The core of the slope is usually composed of rocks that are relatively permeable, which makes it easier for groundwater to flow and concentrate in this location.

Undulating terrain: The sloping core is usually located in a mountain range or highland location in a mountainous area, which makes it easier for groundwater to collect in this location.

Rainfall: The sloping core is often a collection area of rainwater, which makes groundwater easier to form and accumulate.

Groundwater will be concentrated in the core of the oblique part, mainly due to the gravitational effect of groundwater, groundwater will flow to the core due to the change of in-situ stress, forming an oblique flow state.

The anticline rock formation protrudes upward, and the oil has the same hand and has existed for a long time, and there is also natural gas, and a lot of oil also exists as gas, and the gas moves upward, which is consistent with the direction of the rock formation, and it is easy to accumulate gas!

Protruding downward towards the inclined rock formation, the water flows to a low place, and the direction of the water flow is the same as that of the Shasen rock formation, which is easy to gather water!

Groundwater is mainly formed by surface water infiltration, and the downward bending of the oblique structure makes the water easy to infiltrate along the rock layer and hail, so the groundwater in the oblique structure is relatively abundant.

In fact, there is also a lot of groundwater at the fault, and it was there that the groundwater was gathered and exposed before the branches.

Groundwater is mainly formed by surface water infiltration, and the inclined structure is bent downward, and the water is easy to infiltrate along the rock layer, so the groundwater in the inclined structure is relatively abundant.

In fact, there is also a lot of groundwater at the fault, where the groundwater gathers and is exposed.

Characteristics of the oblique nucleus:

1. Tilt is a good structure for storing groundwater.

2. In the original topography, the oblique will be squeezed by the terrain and become the original place, but due to the extrusion of the inclined trough, the material is solid and not easy to be eroded, easy to accept sedimentation, and may become a mountain after long-term erosion.

3. Bend downward to the inclined rock layer, and the force is concentrated in the center, so that the force at each point on the same plane of the inclined structure is uneven, so it is not suitable to build railway tunnels and other projects. Engineering Implications of the Oblique Core Division:

4. Good water storage structure, often with "artesian wells."

Distribution. 5. It can determine the location of the drill well.

Bending downward towards the inclined rock formation, its trough is squeezed and dense and impermeable, allowing the groundwater to collect and store water as easily as a large basin.

Because the slope is generally a valley or something.

The details are as follows: 1. In the anticline, it is easier to find minerals such as coal and iron. Because the rock formation is relatively soft, it is suitable for excavating tunnels and laying pipelines; It is not advisable to build reservoirs.

Coal and oil are formed by tens of millions of years of geological evolution, and are closely related to the new and old rock formations. Some sedimentary rock layers containing oil and gas are deformed due to tremendous pressure, and the oil runs into the anticline, forming an enrichment area.

Therefore, the anticline structure is often a "warehouse" for storing oil, which is called "oil storage structure" in petroleum geology. In general, natural gas is at the top of the anticline structure because it is the least dense, with oil in the middle and water in the bottom. To find oil and gas resources is to find this kind of place first.

2. In the oblique place, it is easier to find groundwater accumulation. Due to the dense rock formation, it is suitable for the construction of reservoirs; Not suitable for the mining of minerals.

It is good to store water in the inclined rock formation, and the amount of water is abundant and easy to find. The inclined structure is conducive to groundwater recharge, and the water of the two wings collects in the middle and infiltrates into groundwater, so the well can be drilled in the inclined trough.

3. At the fault, it is easy to find crystal ores. Because the fault is a rock layer cracking, the surrounding rock layer cracks are wide, and it is not suitable for the construction of reservoirs, tunnels and other projects.

Anticline to find oil and gas. Look diagonally for water.

Anticline is a good oil storage structure, but also conducive to the exploitation of oil and gas, when the exploitation of a period of time, the oil and gas decrease, then the ground will inject water down, because the water density is greater than the oil, you can raise the oil level.

If it's tilting, that's it, oil and gas are not running out yet, and we are still waiting for us to extract them. The inclined structure is conducive to groundwater recharge, and the water of the two wings collects and infiltrates to the middle to form groundwater, so the well can be drilled in the chute part.

Let's see what others have to say.
