Abstract
Digital core technology as a new numerical simulation method, through the core sample reflection of the real core of the complex internal structure, from the micro level in the theory study of core pore structure and residual oil and to improve oil recovery, to provide technical guidance for the production. In order to realize the core of the pore structure in three-dimensional space, this article will Micro - CT image and the Marching Cubes algorithm effectively, realize the three-dimensional reconstruction of digital core. First by using Micro - CT acquisition core section in CT scan images of different time, using the improved Marching Cubes algorithm, gives the method of constructing digital core, will the constructed three-dimensional digital imaging cores and realize the visualization of core pore structure model. The results show that the method presented in this paper the three dimensional data weight building, reconstruction results with complete data volume has the very good consistency, to verify the effectiveness of the new method and advanced.
