Failure Analysis 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.
Failure Analysis of Triangular Drill Pipe
According to the analysis of the working environment and force situation of the triangular drill pipe, the main failure forms of the triangular drill pipe are fracture, plastic deformation (such as bending), and serious wear of the buckle. Among them, the failure form of fracture is the most serious. This failure is manifested in the form that when the shoulder of the head of the triangular drill rod is subjected to a large torsion and impact force, the triangular drill rod will break here. After the fracture occurs, the three-tooth drill bit can only stay in the formation and cannot be taken out due to the loss of connection with the outside world, and the cost of the three-tooth drill bit is quite expensive, which will bring considerable losses to the customer.
