Embodiment Construction

[0133] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0134] See attached figure 1 , figure 1 It exemplarily shows the main steps of a shale CT image reconstruction method in this embodiment. Such as figure 1 As shown, in this embodiment, the following steps can be followed to perform image reconstruction on the shale CT image, specifically:

[0135] Step S101: Acquire a CT image d of a shale sample.

[0136] Specifically, in this embodiment, a synchrotron radiation source can be used to generate an energy-adjustable, monochromatic and naturally parallel X-ray beam, and irradiate the shale sample to obtain a CT image d of the shale sample. In a preferred implementation of this example, the S...

Abstract

The invention relates to the technical field of image processing, particularly provides a shale CT image reconstruction method and device, and aims to solve the technical problem of how to accuratelyacquire microstructure information of a shale sample in a case of not damaging the shale sample. For the purpose, the method in the invention comprises the following steps: acquiring a CT image of theshale sample; and carrying out iterative calculation on a preset regularization model according to the acquired CT image to obtain a reconstructed image of the shale sample. At the same time, the device in the invention can execute all the steps in the above-mentioned method. According to the technical solution of the invention, high-resolution reconstruction can be carried out on the shale CT image, and reconstruction artifacts can be eliminated.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a shale CT image reconstruction method and device. Background technique [0002] Shale gas refers to unconventional natural gas that occurs in organic-rich shale-dominated reservoir rock series. It is continuously generated biochemical gas, thermogenic gas or a mixture of both, and can exist in natural fractures in a free state. and in pores. Based on this, how to accurately obtain the microstructure information of shale is a key issue for shale gas exploration. At present, the observation method of shale microstructure is mainly the surface observation method of shale, such as the observation method based on optical microscope or scanning microscope. However, this method cannot obtain 3D detailed information of shale samples, and it will also cause damage to shale samples. Contents of the invention [0003] In order to solve the above-mentioned problems in ...
