Arrangement and splicing method for fragment-shaped rock core meeting flat sectioning

The invention discloses a tidying and splicing method for fragment-shaped rock cores meeting flat sectioning. From the perspective of splicing manufacturing, through the steps of broken rock core arrangement, fracture splicing, bedding crack trend recognition, columnar rock core interval bonding tin foil strip forming, butt joint sectioning line drawing and the like, rock cores which are broken into different regular sizes can be repaired back to an original cylindrical rock core, so that 1/3 observation of rock core sectioning is facilitated. By means of the method, the sectioned rock core is clearly described, stratum lithology changes and paleontological disturbance conditions in the sedimentary environment can be clearly observed, meanwhile, the bedding microfracture development condition and the bedding trend of the oil shale can be further observed, and the decision basis for follow-up oil shale reservoir development and field operation implementation is facilitated. The method provided by the invention
