What are the tools for drilling water wells? Does a well count as a tool?

The working mode of the drilling machine is the pumping and suction reverse circulation type. Its working principle is: under the action of atmospheric pressure, the circulating liquid flows to the bottom of the well along the annular gap of the wellhole through the sedimentation tank through the backwater ditch, at this time the turntable drives the drill pipe, drives the drill bit to rotate for drilling, and the negative pressure established by the mud pump sucks the debris mud into the inner cavity of the drill pipe, and then rises to the faucet, and is discharged into the sedimentation tank through the mud pump, and the circulating liquid after precipitation continues to flow into the wellbore, so that the reverse circulation drilling work is formed.

The new reverse circulation drill bit provides a wear-resistant drill bit. The cutting edge of each blade is inclined to the horizontal plane, and the diamond composite piece is welded on the edge of each blade and the carbide block is welded on the side. Because the blade of the scraper blade is inclined to the horizontal plane, it is conducive to drilling into the softer ground on the surface; The diamond embedded and welded at the cutting edge is conducive to crushing the rock well section with high hardness and improving the drilling speed. The side of the scraper blade is embedded with welding cemented carbide block, to ensure that the diameter of the well does not become smaller with drilling, which is conducive to the completion operation, according to the conclusion obtained from the experiment, with this drilling tool, the inlet and outlet can be continuously drilled 700 800 meters, that is to say, the 50-meter-deep water well can be continuously drilled more than 15 times, and the original drill bit has to be repaired every time a well is drilled.

Step 1: Configure the appropriate water pump.

After the well is completed, according to the construction drainage situation when drilling the well, the dynamic and static water level of the well and the corresponding water output are measured, and then according to the height difference between the ground and the moving water level and the irrigation method you use, the total head of the pump is determined by the working head of the pump, and the flow rate of the pump is not allowed to exceed the water flow of the well.

Step 2: Reasonable borehole layout.

The location layout of the wellbore should be reasonably laid out according to the actual local hydrogeological conditions, and the existing water source wells nearby can be referred to as the basis for the layout of the wells if there is no hydrogeological data. In areas where shallow groundwater is not abundant, shallow wells must not be drilled blindly; In areas where shallow groundwater is abundant, it is suitable for farmers to build shallow wells, but the layout of the wells should not be too dense, so as not to cause mutual influence between adjacent water source wells.

Step 3: Adopt the right construction methods.

There are two construction methods for large wells: one is the large slotting method, manual excavation or blasting construction; The second is the caisson method, drainage construction or non-drainage construction. In the construction of the counterpart pumping type, two methods of mechanical hammer and manual hammer are generally adopted, and the suction pipe is directly driven into the ground by the gravity of the hammer.

Hello dear, happy to answer your <>

Answer: Pressurized water well calculation tool Pressurized water well is a tool to lead groundwater to the ground, it is made of cast iron, the bottom is a cement block, the well head is the water outlet, the back is thick and early before the thin, the tail is connected with the well center of the pressure handle, about twenty or thirty centimeters long, often used, so that it becomes brighter, the center of the well is a piece of water diversion skin, relying on the force of this water diversion skin and the well center to bring the groundwater pressure Lu brother up.

Summary. There are many types of drill bits and drill bits for drilling deepwater wells, which can be selected according to factors such as well depth, drilling purpose and geological conditions, and the common drill bit types are as follows:1

Ordinary drill bit: suitable for ordinary formation, the drill bit is cube-shaped. 2.

PDC drill bit: It adopts a multi-faceted cubic drill bit, which can be used in harder formations, such as sandstone, limestone, etc. 3.

Tungsten carbide drill bit: The main body of the steel drill bit is inlaid with tungsten steel block, which is suitable for hard formations. 4.

The cutting structure of the drill bit is designed with three types: bevel teeth, three-lobe teeth and ring gear. Bevel teeth are suitable for softer formations, and trilobe teeth and ring gears are suitable for hard rock and broken rock formations. 5.

Cutting surface of drill bits: percussion drill bits, jet drill bits, mechanical combination drill bits, etc. In the drilling process, it is also necessary to use some auxiliary tools, such as drill collars, casing, drill strings, drill bit diffusers, drilling tool hook chains, hydraulic tongs, etc.

Percussion drill bits, jet drill closed heads, machine wax machine combination drill bits, etc. In the drilling process, it is also necessary to use some auxiliary tools for macro cracking, such as drill collars, casings, drill strings, drill bit diffusers, drilling tool hook chains, hydraulic tongs, etc.

Generally speaking, a PDC drill bit with a diameter of 152mm is likely to be between thousands and tens of thousands of yuan, and it is necessary to make a specific inquiry or refer to the market **.

What does the composite piece drill bit fit into.

Composite disc drill bits are typically used to process materials such as sheets, wood, metal, and plastics. They are most commonly used for drilling and reaming, but can also be used for other processing operations, such as removing material from wood or metal or making special shapes. Due to the special design and cutting geometry of the composite disc drill bit, it can efficiently complete many different types of machining tasks in a relatively short time.

1.PDC drill bit: PDC drill bit is a drill bit with multi-sided cutting teeth, which has high cutting efficiency and is suitable for hard rock and sandstone formations.

2.Drill bit: Drill bit is a common drilling tool, and its main role is to carry out drilling operations at the bottom of the well.

According to different types of virtual geological conditions and well depth, it can be ground to select different types of drill bits. 3.Three-wing drill bits:

The three-wing drill bit is a common drill bit, and its main function is to carry out drilling operations at the bottom of the well. The three-wing drill bit is suitable for soft rock formations and mudstone formations. 4.

Drill pipe: Drill pipe is a tool that connects the drill bit and the drilling rig, and its main function is to transmit the power and torque of the drilling rig, so that the drill bit can carry out the drilling operation smoothly. 5.

Drilling pipe: Drilling pipe is a kind of pipe used to support the wellbore and transmit the drilling force, and its main function is to carry out drilling operations at the bottom of the well. In short, in the process of drilling deep-water wells, different types of drill bits and drilling tools need to be selected according to different geological conditions and well depths to ensure the smooth progress of drilling operations.

Dear, the following is related to the extension, I hope it will help you<> drilling depth is generally within 150 meters. Pressurized gas washing rotary drilling rig. On the rotary drilling rig, an air compressor is used instead of a mud pump, and compressed air is used instead of mud to wash the well.

It is usually used in the reverse circulation method, also known as gas lift reverse circulation. It is suitable for use in arid areas and cold permafrost with large well depth and water shortage, and the hydraulic power head drilling rig is in the palace. It is driven by a hydraulic motor through a reducer, and a power head that moves up and down along the tower replaces the turntable and faucet on the rotary drilling rig to drive the drill pipe and drill bit to rotate and cut the rock formation.
