Explain the use conditions of drill pipe
Explain the conditions of use of drill pipes: 1. The rated torque of the selected drill pipe is greater than the large torque of the drilling rig. The rotation speed of the drilling machine shall be less than the rotation speed of the drill pipe (the impact of the moment of inertia of the drilling tool on the drill pipe shall be less than the rated torque of the drill pipe). 2. In a certain stratum, when the sum of the weight of the completely unextended drill pipe cannot make the drill teeth of the drill tool eat into the native soil layer, it is not allowed to use the friction drill pipe to drill. 3. When using friction resistance drill pipe to drill inclined holes, the telescopic direction of drill pipe must be well guided when using casing and drilling tools, and the included angle between the center lines of pipe joints must not exceed 0.4 degrees. 4. Drill vertical holes, and the drilling inclination exceeds "JTJ

What are the aspects of cleaning and maintenance of triangular drill pipe joints?
What are the precautions for cleaning and maintenance of triangular drill pipe joints? "The rod connecting the drill bit and transmitting power in the drilling tool is called triangular drill pipe. The three-pronged drill pipe is a steel pipe with a thread at the tail, which is used to connect the surface equipment of the drilling rig to the drilling equipment or bottom hole device at the bottom of the drilling. The purpose of the triangular drill pipe is to transport drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The three-pronged drill pipe must be able to withstand huge internal and external pressure, distortion, bending and vibration. In the process of oil and gas extraction and refining, the triangular drill pipe can be used many times. Material and processing will cause the triangular drill pipe to break.

Triangular drill pipe connection matters needing attention
Precautions for connection of triangular drill pipe The triangular drill pipe is a steel pipe with a thread at the tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the drilling. The purpose of the triangular drill pipe is to transport drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The triangular drill rod must be able to withstand large torques, twists, bends and vibrations during rotation. During the drilling process, the three-pronged drill pipe can be used multiple times. Precautions for connection of triangular drill pipe (1) The connecting bolts of each part must be tightened to avoid loosening and falling into the triangular drill pipe to cause the rod to be stuck. (2) Quality of heavy-duty joint ring and wire rope card

Structural Difference Analysis of Spiral Geological Drill Pipe and Turbine Geological Drill Pipe
Spiral geological drill pipe and turbine geological drill pipe structural difference analysis Spiral geological drill pipe is now widely used in the domestic demand and application of a selection of geological alloy steel pipe through the conflict welding process planning and production of geological drilling tools. Considering the special geological conditions and different terrains, there are certain requirements for the bending strength, fatigue strength and shear strength of the geological drill pipe. Therefore, in the purchase, on its raw materials and production process to do to deepen the understanding. What is the structural difference between the spiral geological drill pipe and the turbine geological drill pipe? The turbine geological drill pipe is more complex than the spiral geological drill pipe, and the assembly requires accuracy.

Causes and Risk Analysis of Low Pressure Brittle Fracture of Geological Drill Pipe
Analysis of the Causes and Risks of Low Pressure Brittle Fracture of Geological Drill Pipe Geological drill pipe often encounters rock formations with hardness above medium weathered in the foundation construction, which requires a set of pile machine sharp tool with perfect configuration to improve our construction progress. Let's talk about the relevant contents of geological drill pipe, geological drill pipe-the cause and danger of low pressure brittle fracture of geological drill pipe! Low stress brittle fracture of geological drill pipe accounts for a large proportion of the whole drill string failure, and its risk is also very high. Low stress brittle fracture occurs in both geological drill pipe and drill string conversion joints. Such as brittle fracture of geological drill pipe welds and drill stand and drill string adapter screw

Detailed explanation of the operation procedures of triangular drill pipe
A triangular drill pipe is a steel pipe with a thread at the tail, which is used to connect the surface equipment of the drilling rig and the drilling equipment or bottom hole device at the bottom of the drilling. The purpose of the triangular drill pipe is to transport drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The three-pronged drill pipe must be able to withstand huge internal and external pressure, distortion, bending and vibration. The operation rules of triangular drill pipe are as follows: 1. Apair the hole position. Do not form the operation of the triangular drill pipe, but be careful not to "don't" the triangular drill pipe. 2. Release the drill. Overcome the friction force of the hole wall under the action of the gravity of the triangular drill pipe and the drilling tool.
