Industrial CT detection device and detection method for constructing physical simulation experiment model of reservoir control

Abstract

The invention discloses a tectonic control physical simulation experiment model industrial CT detection device comprising an experiment table which can be elevated. The two sides of the experiment table are provided with linear movement mechanisms which can move along length direction in a reciprocating way. A mechanical framework mechanism is arranged between the linear movement mechanisms, and the mechanical framework mechanism is internally provided with an annular mechanism and a driving gear which are engaged with each other. The driving gear is connected with a gear motor and drives the annular mechanism to annularly move. The annular mechanism is provided with a ray tube and a detector. The top part of the mechanical framework mechanism is also provided with a high voltage generator and a cooling machine. The experiment table is detachably provided with an experiment box used for placing experiment material. The experiment box is arranged in the ray irradiation range of the ray tube and accepting range of the detector. The tectonic control physical simulation experiment model industrial CT dynamic detection device capable of realizing multifunctional and high-energy 270-degree scanning is provided without influencing a tectonic control physical simulation experiment model.

Description

Technical field [0001] The invention relates to the field of non-destructive testing, in particular to an industrial CT testing device and a testing method for constructing a physical simulation experiment model for controlling storage. Background technique [0002] Industrial CT device is an important testing device in non-destructive testing. In 1967, the British Hounsfield developed the first medical CT machine for clinical use. In 1979, G.N.Hounsfield and A.M.Cormack won the Nobel Medical Award. In 1974, Ledley of the United States successfully developed a full-body scanning CT. In 1980, the United States and other countries developed high-precision industrial XCT machines. In 1990, American super large industrial CT machines were used to test launch vehicle engines. From the end of the 1990s to the beginning of the 21st century, micro-CT machines began to be gradually applied in the field of scientific research. [0003] Physical simulation of structural deformation is an i...

Problems solved by technology

However, since the physical simulation experimental model of the structure is tested with materials such as quartz sand and silica gel, only the deformation of the surface of the model can be observed during the experiment. Some researchers moved the completed model to a medical CT scan to obtain the internal mechanism of the model.

For example, M. Scott Wilkerson et al., GEOLOGY, v.20, p.439-442, May 1992, Computerized tomographic analysis of displacement trajectory and three-dimensional fold geometry above oblique thrust ramps, but this experimental method can only obtain the final model of the experimental model The internal mechanism of the experimental model during the dynamic deformation process cannot be obtained; because the radiation energy of medical CT is small, only small-sized experimental models can be detected

[0006] At present, at home and abroad, there is no device for 270° scanning using industrial CT to study structural control and physical simulation experiments
