Abstract

The invention relates to a shipborne rock core Ct transmission scanning imaging device and belongs to the technical field of natural gas hydrate basic physical property measurement. The device comprises a CT scanning support, a CT scanning system and a computer system; the CT scanning system is arranged at the center of the CT scanning support, and a passage for scanning a to-be-tested article isarranged at the center of the CT scanning system. due to the structure setting of the CT scanning support and the CT scanning system, the structure of the original CT transmission scanning imaging device is simplified; the CT scanning system solves the problems of fuzziness and double image during scanning imaging; a radiation isolation device effectively prevents leakage of scanning radiation; and drive systems at two sides of the CT scanning system ensure that the rock core sample feeding process is smooth, and the definition and accuracy of scanning imaging are further promoted.

Description

technical field [0001] The invention relates to the technical field of natural gas hydrate basic physical property measurement, in particular to a ship-borne rock core CT transmission scanning imaging device. Background technique [0002] As a new type of clean energy, natural gas hydrate is very important for the study of the occurrence state, distribution characteristics and basic physical properties of natural gas hydrate; the current CT transmission scanning imaging device cannot meet the requirements for the measurement of natural gas hydrate cores. Requirements, especially complex seabed natural gas hydrate cores, while the existing CT transmission scanning imaging device has a complex structure and is inconvenient to operate, radiation is easy to leak, and the scanning image is unclear and ghosting. Contents of the invention [0003] In order to solve the problems that the existing CT transmission scanning imaging device cannot be applied to the scanning operation o...
