Friction welding drill pipe tells how to maintain drilling machine equipment in rainy season?

Drilling machine structure: traction type, vehicle-mounted type, vehicle-mounted type. General drilling rig consists of diesel engine, friction clutch, gearbox, transfer case, drive shaft, mud pump, clean water pump, vacuum pump, turntable, faucet, hoist, hydraulic system, control mechanism, mast, friction welding drill pipe, frame, etc. In the rainy season, the machinery is easy to rust, therefore, the drainage and irrigation machinery should be properly maintained to increase its service life.

What is the necessary work in the drilling work of the outer flat drill pipe?

The first drilling team is a step-by-step process when drilling wells, and it needs to transition from coarse to fine work in order to do a good job in drilling wells. Therefore, the outer flat drill pipe will look at the main contents of the three-time drilling.

DTH Drill Pipe Analysis Groundwater Dynamic Prediction Considerations

Groundwater dynamics refers to the process of changes in groundwater level, water volume, water temperature, chemical composition and other factors over time. Drilling a well needs to find a place with sufficient groundwater, so how can we predict the groundwater dynamics? DTH drill pipe will explain it to you.

What are the precautions for the terrain of the water well drill pipe drilling team?

In order to find groundwater resources, water well drill pipe uses well drilling machine equipment to carry out drilling water intake project, that is, groundwater needs to be found according to geological conditions at different points. From geological analysis, there are usually three kinds of geology that can contain water, namely basalt formation, gypsum layer, quicksand layer and so on, which are the most common geology encountered by well drilling machine.

What are the technologies for drilling wells under friction welding drill pipes?

In geological exploration and geological engineering, it is beneficial for drilling equipment to drill underground. For cylindrical round holes with small diameter and large depth, it is called drilling.

DTH drill pipe tells us: What are the methods of flushing and dredging?

The reasons for the formation of silt wells include sand in the water layer, excessive strainer holes, and well wall damage. All these will cause sediment deposition and blockage in the lower part of the well, block part of the screen pipe, and affect the water outlet of the well. These problems can be solved by well washing. Below, the down-the-hole drill pipe introduces several methods of well washing and dredging.

Drill pipe manufacturers tell us which types of drilling fluids can be divided?

Drill pipe manufacturers tell you that drilling fluid is indispensable in drilling engineering, and drilling fluids that are not used in different regions are also different. Drill pipe manufacturers have found the following drilling fluids for you.

What are the working steps of the drilling engineering team under the down-the-hole drill pipe?

The drilling hole is drilled by the hole well to a certain formation depth or level, the next layer of pipe sleeve, and then changed to a smaller size of the down-the-hole drill bit drilling.
