“…The piston rod connects the piston and the crosshead. At both ends of the piston, the rod ends with a conical and a cylindrical threaded part that connects to the piston body and the cross-head or with the extending rod [5][6]. The rod and the piston have parts such as the connecting thread, the conical head of the rod, and the interchangeable piston hole, as regulated by the API 7K norms.…”

This study highlights the operational and practical advantages of using triplex mud pump systems in favor of duplex systems to optimize drilling capabilities under specific operational conditions. Additionally, the material selection of the piston subassembly was analyzed and simulated under operational parameters in SolidWorks to determine the advantages of using HNBR over NBR elastomer materials.

“…There are a large number of wear-resistant products developed in the industry, but with different performances, and it is difficult to ensure both cost and wear resistance (Caltaru et al, 2020;Fedorova et al, 2018;Coronado et al, 2009). Bead weld (BW) technology is widely used to improve the wear resistance of drill pipe joints by virtue of its simple equipment operation and stable welding layer quality and low cost; however, in the surfacing operation, the heat-affected area of the drill pipe joint is large, and the repeated surfacing property varies greatly because of the different wear-resistant products, and it is difficult to guarantee the wear resistance and anti-friction properties (Coronado et al, 2009;Buchely et al, 2005;Truhan et al, 2007).…”

Purpose The purpose of this study is to solve the oil drill pipe joints and casing excessive wear problems and to improve the drill pipe joint-casing wear resistance and anti-friction properties. Design/methodology/approach On the surface of the drill pipe joints using oxyacetylene flame bead weld (BW) wear-resistant welding wire ARNCO-100XTTM prepares welding layer, high-velocity oxygen fuel (HVOF) Cr3C275-NiCr25 prepares coating and subsonic flame spray and remelt (SFSR) Ni60 prepares coating, then comparing and analyzing the friction and wear of the three types of wear-resistant layers and the casing under the condition of 1.8 g/cm3 mud drilling fluid lubrication. The wear resistance and anti-friction performance of the drill pipe joints were evaluated based on the wear situation, finally revealing its friction and wear mechanisms. Findings Three types of wear-resistant layers can improve the surface wear resistance of drill pipe joints, the wear-resistant layer and the substrate are well combined and the welding layers and coating are both dense and uniform. The wear resistance of the HVOF-Cr3C275-NiCr25 coating is 10.9 times that of the BW-ARNCO-100XTTM weld layer, and the wear resistance of the SFSR-Ni60 weld layer is 2.45 times that of the BW-ARNCO-100XTTM weld layer. The anti-friction properties of SFSR-Ni60 welding layer is the best, followed by HVOF-Cr3C275-NiCr25 coating, and the anti-friction properties of BW-ARNCO-100XTTM welding layer is the worst among the three. Originality/value The research results of this paper have great practical value in the process and material of improving the wear resistance and anti-friction performance of the drill pipe joint casing.

High-precision tapered threads are widely used in hard-loaded mechanical joints, especially in the aggressive environment of the drilling of oil and gas wells. Therefore, they must be made of workable materials often difficult to machine. This requires the use of high-performance cutting tools, which means the application of non-zero geometric parameters: rake and edge inclination angles. This study is based on analytical geometry methodology and describes the theoretical function of the thread profile as convoluted surfaces dependent on the tool’s geometric angles. The experiments were conducted using a visual algorithm grounded on the obtained function and prove the practical use of the scientific result. They predict the required accuracy of thread made using a lathe tool with a rake angle of up to 12°.
