Description
Technical Field
The invention belongs to the technical field of drilling operation, and particularly relates to a ground source hot water well drilling machine.
Background
China enters the development era of winter heating of green energy and clean energy, one of the heating modes is to develop and utilize heat energy stored underground, and the water temperature entering a user heating facility reaches the requirement of winter heating through matched heat energy extraction, aggregation and temperature increasing equipment. In the circulation process of water in the underground U-shaped pipe, the ground source heat pump system and the user heating facility, the water circulates in the closed U-shaped pipe, no water-water and water-ground connection with the outside occurs, no fuel oil heating is needed, and no coal heating is needed, so the underground heat energy of the middle-deep layer is sustainable and environment-friendly utilization of green energy and clean energy.
In northern China, particularly in cold regions, the heat supply time in winter is as long as 5-7 months, huge energy requirements exist, and the distribution and acquisition of coal, oil and electric energy sources in the regions are extremely unbalanced. Ground source heat energy (mainly expressed as temperature change below the earth surface and temperature increase with depth) is ubiquitous. According to the general condition, the temperature-variable layer can be divided into 3 temperature layers from the earth surface to the earth interior from the temperature perspective, namely a temperature-variable layer, a constant temperature layer and a temperature-increasing layer; the buried depth of the constant temperature layer is generally 70-100m in the north of China, the constant temperature layer is a temperature increasing layer from the bottom of the constant temperature layer to the direction of the earth center, and the numerical value (X ℃/100m) increased when the earth temperature is increased by 100m is the so-called earth temperature gradient. Generally, X =2-4 (there are also special cases of an abnormality in the earth temperature, X > > 4).
Heating by utilizing a ground source heat pump system is a mature technology; the ground source heat pump system heats and can not separate from the well drilling, and the well drilling technology is relatively more mature.
The ultra-deep well drilling tool can drill ultra-deep wells with the depth of more than or equal to 8000m in China, and is more common like common well drilling with the depth of more than 100 m.
The current problem is that special drilling rigs for middle-depth drilling of 400-600m are still rare. When 400-inch and 600-meter drilling is carried out, either a cart is pulled by a large horse (kilometer drilling rig) so that the cost is high, or a cart is pulled by a small horse (hectometer drilling rig) so that the efficiency is low.
In addition, since the length of the drill pipe is generally 6m, the drill pipe can weigh 500kg, and 600m deep drilling needs about 100 drill pipes, and the total weight is as much as 5 tons. The method is labor-consuming, time-consuming, efficient and high in cost when the drill rods are assembled and disassembled and when the drill rods are shipped.
