Rock core information model establishment method based on 3D printing and NFC technology

Abstract

Provided is a rock core information model establishment method based on 3D printing and NFC technology. The method includes the following steps of (1) using a rock core scanning instrument to perform circumference expansion scanning and planar scanning so as to acquire a rock core omnibearing high-definition image; (2) importing the image to Autodesk 123D, and automatically synthesizing a 3D model; (3) selecting Solidworks software to process the exported .stl format files; (4) vividly restoring the surface of the rock core and adding information to the parts of the rock core in classification; (5) attaching the NFC chip to the inside of the corresponding rock core; and (6) uploading the rock core model and the NFC attaching part corresponding graph to the corresponding website. For the problem that a rock core in the prior art is easily weathered and eroded and is permanently disappeared after being cut, the fewer and non-regenerated rock cores can be maximally utilized, the embarrassment that researchers want to do the study, but no rock core can be used for test can be prevented.

Description

technical field [0001] The invention relates to 3D printing of lithology models, NFC technology and informatization, and belongs to the fields of earth science and geological exploration. More specifically, it is a method for establishing a core information model based on 3D printing and NFC technology. Background technique [0002] In actual geological research, production units usually use different methods to preserve the cores obtained by drilling samples, but it is inevitable that the rock samples will be excised by researchers from different units for experiments. recovery, so there is no core available for old wells in the later stage. If the core is weathered and denuded due to preservation problems, the core taken out will be damaged again. All of these have caused great difficulties in geological research and remaining oil research, and the simple core scans cannot vividly show the various fractures and rock shapes of the core. Therefore, it is necessary to esta...

AI Technical Summary

Problems solved by technology

[0003] The existing core observation is mainly for scientific researchers to go to the core room of the research area to observe the core. If the area has been mined for a long time and a lot of experimental work has been done, the existing core data may be incomplete or there is no required core to carry out own experiment

Moreover, there are relatively high requirements for the preservation of rock cores, but as time goes by, it is inevitable that the cores will be lost, and the existing preservation of lithology information is mostly based on pictures or text information. For some details on the cores, only Make descriptions or observe photos, which may cause different perceptions of core information from person to person
