Many deep water wells have been drilled in Hangjinqi formation.

Deep water wells can usually be drilled to a depth of 300 meters.

Deep well refers to a well used to obtain deep groundwater, which is mainly used to obtain deep groundwater, that is, water below 20 meters underground. Deep water wells are usually common in arid areas such as northwest China. The drilling depth of the deep water well is 20-300m, and the water intake is1-100t per hour.

Advantages:

(1) Just pay less electricity fee for the water pump, and don't pay water fee;

② It can be used as both edible water and industrial and commercial water;

(3) The water from the deep rocks in the earth's crust contains all the minerals necessary for human body, with no pollution and sweet taste;

④ Groundwater can temporarily alleviate water shortage;

⑤ You can use your original water pipeline to transport groundwater, and you can drink groundwater as soon as you turn on the tap, which is as convenient as tap water;

⑥ Generally, there is water within 40 meters underground, so the project cost is reasonable and the construction period is short;

⑦ The wellhead is small, occupying only 3-4 square decimeters, which will never affect the beauty of home and normal production;

⑧ The constant temperature of groundwater is 24℃, which is warm in winter and cool in summer.
