Embodiment 1

[0022] The invention uses digital technologies such as three-dimensional CT reconstruction and 3D printing to construct complex rock cores. CT machine scanning can perform non-destructive detection of rock cores, and can understand the internal structure of rock core samples in different geological layers. Wherein the CT machine includes: ① X-ray source, used to generate X-rays required for scanning samples; ② Rock core sample holder, used to fix and precisely rotate the rock core samples to be scanned; The core sample absorbs the attenuated X-rays. The above-mentioned components are all connected to a computer, and the computer is used as an operating platform to accurately control the parameters of the above-mentioned components, and output the scanning data of the core sample.

Abstract

The invention provides a complicated rock core preparation method based on CT scanning and 3D printing. Based on a combined technology of CT scanning and 3D printing, the reappearance of an underground rock pore structure characteristic is realized, and the visualization of oil-gas-water distribution inside a rock core can be achieved. Through a 3D printing technology, the visualization and actualization of the digital rock core and a network model can be achieved, and the underground core pore structure can reappear in a real object form. More importantly, with the continuous input and development of unconventional oil-gas fields such as carbonate rocks, shale oil and gas and compact oil and gas, the complicated rock core preparation method has the advantage that by using the combined technology of CT scanning and 3D printing, a new thought and method is provided for representation and preparation of special rock cores.

Description

technical field [0001] The invention relates to a complex core preparation method based on CT scanning and 3D printing, and belongs to the technical field of physical experiments of oil and gas field development engineering. technical background [0002] In the process of oil and gas field development, many macroscopic properties of the reservoir, such as permeability, capillary pressure, relative permeability, etc., all depend on its microstructure and the physical properties of the fluid in the pore space, that is, the microstructure and fluid properties are fundamental. , macroscopic properties and phenomena are representations. Therefore, it is not complete to study the seepage law of core porous media only from the macroscopic scale, and the internal microscopic nature of the macroscopic phenomenon is not clear enough. The practical application of petroleum engineering is very strong. Oil and gas resources are stored underground at a depth of several thousand meters. T...
