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： 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.

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.
