What should be paid attention to when running casing during drilling?

The main matters needing attention in casing running operation are divided into three parts: site, gate front and wellhead.

06-03

What are the precautions for drill pipes?

When the scratch mark on the drill pipe body is about 1mm deep and is in a spiral state for more than one turn, please use it with caution. Prevent the drill pipe from being broken during construction, causing greater losses.

06-07

In what ways has the geological drill pipe helped mankind?

Under normal circumstances, because the underground environment is harsh, and in different areas, the composition of the underground soil and rock are different, so for the geological drill pipe, it is necessary to have the qualification to work in this complex underground environment.

06-09

What other tests are needed for finished drill pipes to leave the warehouse?

The drill pipe is a thin-walled pipe, which is subjected to axial force, bending moment, centrifugal force, torsional force and dynamic load during the drilling process, and the premise of the working condition is extremely harsh.

06-16

The new down-the-hole drilling opportunity has a running-in period, what are its characteristics?

Full attention should be paid to the use and maintenance of the running-in period of the down-the-hole drill and the impactor.

06-22

What are the specifications and materials of the most important trenchless drill pipes for horizontal directional drilling?

The steel grade of trenchless drill pipe is S135, which ensures the quality of trenchless drill pipe.

07-06

Geological drill pipe use and maintenance process:

The spare drill pipe shall be brushed clean, coated with anti-rust oil, and covered with thread protector. The drill pipe shall be padded with three fulcrums to prevent bending and deformation, and no heavy objects shall be placed on the drill pipe.

What do you need to pay attention to when using trenchless drilling rig in the construction process?

The use of this trenchless technology will not have a great impact on people's lives, but also a good protection of the surface, will not produce a lot of dust like excavation technology. Trenchless technology was introduced into China in the 1990 s, mainly used in horizontal directional drilling, pipe burst impact, water supply, drainage, electricity, communications, gas and other fields of new pipeline construction and old pipeline repair and other technical methods.
