    摘要: A bottom cylinder for a high-temperature and high-pressure environment simulator of a high-fidelity corer is provided. The bottom cylinder includes a cylinder barrel. The bottom of the cylinder barrel is provided with a cylinder base. The piston is provided inside the cylinder barrel and divides an inner cavity of the cylinder barrel into a rodless cavity and a rod cavity. The piston is provided with a piston rod. The outer wall of the cylinder barrel is provided with an oil inlet hole communicated with the rodless cavity, an oil outlet hole communicated with the rod cavity, and a reserved hole. The lower end surface of the piston is provided with a first buffer ring, and the upper surface of the cylinder base is provided with a second buffer ring mated with the first buffer ring. The bottom cylinder is applied to the simulator for oil and gas resource exploitation.

    摘要: The present disclosure provides a rolling and sliding adaptive device for guiding and fixing a drill pipe. The rolling and sliding adaptive device includes a mounting platform, where the mounting platform is provided with a through hole for the drill pipe to pass through. Multiple rolling and sliding support mechanisms are arranged around the through hole. The rolling and sliding support mechanisms each include a support seat. The support seat is provided with a contact element telescopic and swingable on the support seat. A telescopic drive mechanism is provided between the contact element and the support seat. The contact elements on the multiple rolling and sliding support mechanisms form a funnel-shaped structure with a large upper part and a small lower part around the through hole. The rolling and sliding adaptive device is used on a deep in-situ high-fidelity coring calibration platform for accurate positioning of an assembly process of a multi-section drill pipe bin, thus ensuring the assembly accuracy of the multi-section drill pipe bin and stable support and fixation for the assembly and work of a coring system using the drill pipe.
