Abstract
A method for imaging three-dimensional topography with high precision, which overcomes the disadvantage and deficiency of low precision in observing three-dimensional topography of hydraulically fractured cracks of rocks, improve the precision in observing three-dimensional topography of cracks in rock hydraulic fracturing test, and benefit for scientifically understanding regular pattern of development of hydraulically fractured cracks of rocks. The technical solution comprises: hydraulically fracturing the rock with aqueous solution containing fluorine nuclides; forming hydraulically fractured cracks; in the process of fracturing, loading a fracturing apparatus while rotating the same; emitting an x-ray beam from an x-ray source, which penetrates the rock and reaches a CT detector; optical signals transmitted by the fluorine nuclides inside the rock being received by a high resolution planar array SiPM detector for nuclides; performing image fusion of nuclides tomographic scanning data and CT data to implement high precision imaging for three-dimensional topography of cracks in rocks.
