▎ 摘　　要

NOVELTY - The holder has a shell (1) whose outer wall is provided with an annular lug boss along a circumferential direction. A sealing cover (2) seals the opening end of the shell. An inner cylinder (7) is fixed in the shell. Ends of the inner cylinder are provided with a non-magnetic plug (5) to form a cavity for placing a rock core (6) in the inner cylinder. An end of a liquid inlet pipe (9) and a liquid outlet pipe (8) passes through the sealing cover and extends into the shell, and through the non-magnetic plug at two ends of the inner cylinder. A material of the shell comprises zirconium oxide ceramic, carbon ceramic composite material or basalt fiber. A material of the sealing cover and the non-magnetic plug comprises non-magnetic metal, zirconium oxide ceramic, carbon ceramic composite material or basalt fiber material. The material of the inner cylinder comprises carbon graphene composite material. A material of an insulating coating (4) comprises ceramic and nano-material. USE - Rock core clamper for a nuclear magnetic resonance displacement experiment device (claimed) used in oil and gas exploration and development field. ADVANTAGE - The clamper simulates the process of fluid/gas under the condition of domestic complex stratum through reservoir rock so as to satisfy experimental requirements, thus ensuring real-time observation precision of the nuclear magnetic resonance experiment process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a nuclear magnetic resonance displacement experiment device. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a rock core holder based on non-magnetic material. 1Shell 2Sealing cover 3Connecting piece 4Insulating coating 5Non-magnetic plug 8Liquid outlet pipe 9Liquid inlet pipe 10Temperature measuring opening 11Pressure measuring port 12Pressurizing port
