What is the reason for drilling shallow wells to deepen the depth of the well? 200

Generally, when the water does not come up at all, or when it hits the salt and stone layer, the well must be deepened. Or when the water quality is not good, it is easy to deepen the well.

The reason for the deepening of the tight body when the submarine appears, the most important thing is that it may not be able to hit the water without encountering the groundwater, so it is necessary to deepen the depth of field, and then when it hits the ground submarine, the reason for the deepening of the tight body, the most important thing is that it may not meet the groundwater and cannot hit the water, so it is necessary to deepen the depth of field, and then hit the underground water pond long, and then it can be out of the water and can be used.

Then you must be a diving well, and if you hit that depth, if there is still no water, then you must deepen it, and if you deepen it, you will be able to get out of the water.

If you dig a well, you originally dig a diving well, and then you deepen it, but in fact, it is because you can't get out of the water when you hit the submarine, and then you want to see if you can dig deeper, and see if you can get water.

I think that when the water is not produced enough and the water quality is not good when it reaches the predetermined depth, the depth of the well will be deepened to ensure the quantity and quality of water.

If the water level of the well is not enough, that is, the water seepage capacity is not strong, it will continue to deepen the depth, so that a certain amount of backup water can also be reserved.

The drop in the water level of the shallow well is not enough for normal use, and the garden can not be watered, and the knowledge will be deepened.

What is the reason for drilling shallow wells to deepen the depth of field? Of course, the well water is not good to drink, or the well water is not enough to pump, so the well will be deepened.

As the groundwater content decreases and the water level drops, it is necessary to deepen the depth of the well.

The insufficient amount of water in the well leads to poor water output capacity of the submersible pump.

In addition to the water level, the most important thing is the water quality, if it is a drinking water well, it is the water quality that needs to be considered, and most of the shallow water is not good now, and the groundwater needs to be deepened.

Drilling wells is generally 15 to 100 meters. Drilling wells are divided into deep water wells and shallow water wells, the depth of drilling wells in different areas is not the same, shallow water wells refer to places with sufficient water volume, generally 15-20 meters can produce water; Deep-water wells, on the other hand, are located in places where the amount of water is insufficient, so they generally have to break through the rock layers to a depth of up to 100 meters.

Drilling wells are mainly used for the development of groundwater resources, including domestic water, agricultural water and industrial water and other drilling work, the main tool used in drilling is the drilling machine, and the working mode of the drilling machine is the pumping reverse circulation type. The principle of its operation is: at atmospheric pressure.

Under the effect of circulating the fluid by the sedimentation tank.

It flows to the bottom of the well along the annular gap of the wellbore through the backwater ditch, and the cycle is repeated, forming a reverse circulation drilling work.

How deep do you need to drill a well to get water? This depends on the level of groundwater in your home. If your home is located in the Yangtze River Delta area, you can generally hit five or six meters to get out of the water, if you are located in the plateau area, some need to hit a few hundred meters without water, right.

How deep do you need to dig a well to produce water, this should be decided according to the actual situation of your hometown, the south has abundant water, the groundwater level is relatively high, it is relatively dry, the water level is low, and the well can only be drilled dozens of meters to produce water.

This also depends on the geographical location, some places are a little more than three meters out of the water, and there are good places where less than three meters will be out of the water, and some places have to be four meters in a little water, so this now depends on the place.

According to the location you choose, the stratification of groundwater is related, as long as the selected location is more than ten meters to the water is also normal, if the location is not right, dozens of meters or even hundreds of meters without water is normal. Therefore, it is also necessary to have a certain amount of experience in choosing a place to drill wells.

It depends on the local groundwater level. At the end of May 2019, the average groundwater depth in the plain area of Beijing was meters.

Hello, there is no way to determine this, only according to the depth of groundwater to determine the depth of the well, but try not to or less wells, this backward method for the destruction of groundwater resources is huge, so take care of the environment and the earth from me.

How to say this, my well is three meters deep, and then it is not enough to dig two meters, this is actually very shallow, some wells are dozens of hundreds of meters without water, how deep to dig, you need to see the geographical location.

The well is as deep as it sees the water.

The depth depends on how deep the water layer is on your side, not the deeper the better, just the right one.

According to the geological conditions, different towns at the same county level are also very different, and your address.

How deep do you need to drill a well to produce water, and how deep do you need to drill a well to produce water?

The depth of drilling wells in different parts of China is also different, and it can generally be divided into the following situations: In the Jiangnan area, water can generally be produced from 15 to 20 meters. 2.

In the place where the water volume is not sufficient, it is necessary to drill a well of 100 meters or hundreds of meters to break through the rock layer, which is a deep water well to produce water, and a scientific and reasonable well formation process should be adopted.

Under the same geological conditions, in order to maximize the water output, the smallest depth, the best water quality and the longest service life, it is very important to make the well process scientific and reasonable.

1.The water filter pipe should be directly facing the aquifer. Once the two are misaligned, the water inlet resistance will be much greater, and the depth will be increased. For this reason, it is necessary to carry out physical exploration wells before the pipe is lowered to accurately determine the location of the aquifer.

2.The opening ratio of the water filter pipe should be sufficient. No matter what kind of pipe opening, the porosity ratio should not be less than 10%. Most of the cement pipes produced by the soil method are only 1-2%, and the water ingress resistance is very large, so it is not allowed to shout frankly.

3.There should be a cushion between the water filter pipe and the filter screen. If there is no cushion bar, the filter screen is tightly attached to the well pipe, and only the mesh facing the water inlet hole can enter the water, which is easy to cause blockage, and seriously affects the water output and service life of the well.

4.The mesh mesh and the size of the gravel fill should be appropriate to the aquifer. Otherwise, it will either block the water or muddy water will cause it to be in the well.

5.If mud is used for drilling, the wall should be broken and slurry changed before the pipe is down. At present, there are serious problems in the society, such as arbitrary configuration of water filter pipes, too low opening rate of water filter pipes, no reinforcements, unqualified filter screens and gravel filling, and incomplete slurry replacement of broken walls, which need to be improved urgently.

Most of the recharge wells of ground source heat pumps are not well recharged, which is an important reason. The professional drilling team of our groundwater research institute has formulated a complete set of drilling construction procedures for the above problems, and the drilling effect is very good whether it is positive circulation or reverse circulation.

Fourth, it is necessary to carry out the pumping test, reasonably select the water pump, and the pumping water test can be carried out in combination with the well washing. Before the end of the well washing, the water output of the pump, the static water level, the moving water level, the water output of Zheng Zhitong of the unit of the well should be calculated, the maximum possible water output and the suitable pump water volume. At present, the vast majority of wells do not have the above data, only know whether the pump is enough to pump, can only blindly select the pump, how deep the well is drilled to choose the pump with high head, serious waste of energy.

Summary. Hello! Glad to answer for you :

It is better to drill a deep water well and drill as deep as possible. Between 20 meters and 300 meters. A deepwater well is a well that takes groundwater at a deep level.

They are usually found in arid regions such as northwest China. They are mainly used to obtain deep groundwater (i.e. water below 20 meters below the ground). Most of the wells are more than 20 meters deep, and professional exploration and drilling equipment is required when digging wells.

It is no longer surface water that is extracted from the well, but groundwater. The depth of the well is large, and only pumps can be used for pumping operations.

2. Definition: The drilling depth is 20 meters to 300 meters. The water intake is 1-100 tons per hour.

The water temperature is around 17 degrees, which is widely used for production, living and factory cooling. The deep well is concealed and does not occupy the site, the diameter of the wellhead (10-30 cm), and the construction conditions are not high. Deep well pumps can be used to pump water and can supply water all year round.

Deep well water can replace expensive tap water.

Is it reliable for me to hit 80 meters.

Hello! It's okay to hit 80 meters. According to on-site requirements. As long as it doesn't exceed 300. It is no longer surface water that is extracted from the well, but groundwater. The depth of the well is large, and only pumps can be used for pumping operations.

Will it be hit by others for 100 meters in the future, and will there be less water for me at 80 meters?

Hello! Will it be hit by others for 100 meters in the future, and will there be less water for me at 80 meters? This is not going to be reduced. You can rest assured. Thank you.

Between 20 meters and 300 meters. Deepwater wells are wells that obtain deep groundwater, usually common in arid regions such as northwest China, and are mainly used to obtain deep groundwater (i.e., water below 20 meters below the ground). Most of the wells are more than 20 meters deep, and professional exploration and drilling equipment is required to dig the wells.

It is no longer surface water that is pumped from the well, but groundwater, and the depth of the well is large, and only the pumping machine can be used for pumping operations.

Definition: Drilling depth is 20 meters - 300 meters. The water intake is between 1 and 100 tons per hour.

The water temperature is about 17 degrees, which is widely used in production, living and factory cooling. The deep well conceals the site, the diameter of the wellhead (10 30 cm), the construction conditions are not high, the water is pumped with a deep well, and the water supply can be supplied all year round, and the deep well water can replace the most expensive tap water.

Wells are generally best metre deep.

The depth of drilling wells in rural areas should be based on one's geographical location, with a depth of several tens of meters in some places and two or three meters in others. However, the best depth is deep Jiong meters, this depth of water is less heavy, basically the water in it flows far away, the surface water will not invade, and we take water is also very convenient, deep is not good to take water, shallow surface water is easy to invade.

If it is non-domestic water, only the lead should be sufficient in water, the water source is rich and shallow, and the domestic water should not only look at the quantity but also the quality, and the water quality can be sufficient, and the depth is generally several meters to hundreds of meters or thousands of meters, but the deeper the better, so quantity and quality are the key.

Precautions for drilling wells:

1. Choose a place as far away from sewers, sewage pipes and rivers as possible.

2. When drilling wells, bricks must be lined in time, and the deeper the hole, the more timely lining must be made to prevent collapse.

3. When using the culvert pipe as the inner tank, you can dig to the depth at one time and start to release the pipe. However, the soil must belong to the geological area that is not prone to collapse.

4. The depth of drilling the well must be dug until there are obvious water traces in the soil below to stop.

5. The back cover of the brother's banquet must be made of clean stones or large stones that are not easy to weather.

6. All processes must pay attention to safety, especially the diggers below must wear safety helmets, and when they reach a certain depth, they must have equipment to press down the air from above. Personnel who were found to have landslides were evacuated immediately. In general geology, there will be landslides. <>
