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.

摘要： An assembly method for a deep in-situ high-fidelity coring calibration platform includes the following steps: S1: fixing a core bin assembly subsystem on a preset ground foundation and fixing a simulator of a core bin on a mounting base plate of the core bin assembly subsystem; S2: driving a cylinder and driving the mounting base plate to move to a preset position; S3: driving a servo motor and controlling two clips to move close to each other; S4: fixing a drill pipe bin assembly subsystem on the ground foundation; S5: assembling multiple sections of a drill pipe bin in turn; aligning and connecting a bottom of the drill pipe bin to the simulator, and aligning and communicating the top of the drill pipe bin with the lower part of an adaptive drill pipe guide structure; and S6: driving the adaptive drill pipe guide structure to perform accurate positioning.

摘要： A real-time temperature-pressure detection and rapid processing system for a calibration platform, comprises an inner return pipe, and a water supply pipe is provided therein with an inner water supply pipe. An outer wall of the inner water supply pipe is connected with an inner wall of the water supply pipe through multiple springs. An outer wall of the inner return pipe is connected with an inner wall of a return pipe through multiple springs. The return pipe and the water supply pipe are made of a thermosetting polymer material. The multiple springs, the inner water supply pipe, and the inner return pipe are covered with a heat conducting material. The system further includes a temperature-pressure detection assembly. The assembly includes multiple infrared sensors arranged at two sides of the return pipe and the water supply pipe, a booster pump, a heater, and infrared sensors connected with a control unit.
