Additive Manufacturing (3D printing) technology has become a necessary supplement to traditional additive manufacturing because of its unlimited structure, short production cycle, high density and high strength. As the core component of the through the drill pipe tool neutron compensation instrument, the pressure supply silo must integrate the neutron probe and other components in the limited space and must bear the complex loads such as high temperature (175°C), high pressure (140 MPa), tension and so on. The structure design and manufacturing process of the instrument are put forward high requirements. The Integrated Design, mechanical simulation, printing support optimization and high temperature and high pressure limit mechanical test of the pressure supply silo are studied. The integrated structure design and machining problem of the welding assembly (15 parts welding) of the pressure source cabin is solved, and the structure optimization and the mechanical properties of the material are realized. The near-shape part of the material adding technology simplifies the processing procedure, greatly reduces the cutting amount, and improves the material utilization ratio. The one-time integral forming of the curve hole simplifies the processing and assembly process. 12 samples were tested at 175°C, 140 MPa, 30 tons of maximum safety mechanics and limit mechanics simulation. The results show that the integrated design and processing technology of welding components based on additive manufacturing technology can meet the technical requirements of pressure source cabin, the problems of unstable structure and process reliability and complex machining are solved effectively, and a new feasible technical route for the integrated design and manufacture of similar welding components is opened up.

Research on the application of additive manufacturing technology in the design and manufacture of logging tools

Yiduo Wei, Xiao Ma, Ying Zhou, Hongbo Jia, Junli Chen, Shuihang Wang

Proceedings Volume 12979, 129793Y (2024) https://doi.org/10.1117/12.3015262

Additive manufacturing (3D printing) technology has been applied in the production and manufacturing of complex special-shaped, high-precision, and key important logging instrument parts due to its characteristics of unlimited modeling structure, short production cycle and high mechanical properties. Through the research on model optimization, forming parameters and printing support of special-shaped heavy parts of logging instruments, the processing problems of density probe shell with internal cavity and microporous special-shaped plates, multiple sealing parts, space curved turbines, impellers and thin-wall grid radome that are easy to deform are solved. At present, the instrument plate body, turbine, guide wheel and density probe housing have been mass-produced, and the radome meets the design requirements after assembly and testing. At the same time, through the research on the cross-sectional growth process of the same material, the trial production of samples was completed, and the 140MPa tightness and 30 tons of ultimate mechanics were tested, and the samples were sealed, and all parts were intact. It is proved that the additive manufacturing craft meets the design requirements. Meanwhile, it establishes the foundation of upcoming integrated molding craft of components used to be finished by welding.
