摘要： Porous body data 60 in which position information and type information are correlated is reference to take a curved surface solid including a parent virtual sphere and child virtual spheres as a virtual curved surface solid, and place multiple virtual curved surface solids so as to fill in space pixels with curved surface solid pixels occupied by virtual curved surface solids (steps S230 through S320). Repeating this process, by placing multiple virtual curved surface solids within space in a porous body, the microstructure of the porous body is analyzed precisely. As for analysis, deriving of in-plane uniformity index γ x , spatial uniformity index γ, pressure drop P, flow-through velocity T, and equivalent diameter d for example, and acceptability determination based on derived values thereof, is performed.

摘要： Embodiments of a method of pore type classification for petrophysical rock typing are disclosed herein. In general, embodiments of the method utilize parameterization of MICP data and/or other petrophysical data for pore type classification. Furthermore, embodiments of the method involve extrapolating, predicting, or propagating the pore type classification to the well log domain. The methods described here are unique in that: they describe the process from sample selection through log-scale prediction; PTGs are defined independently of the original depositional geology; parameters which describe the whole MICP curve shape can be utilized; and objective clustering can be used to remove subjective decisions. In addition, the method exploits the link between MICP data and the petrophysical characteristics of rock samples to derive self-consistent predictions of PTG, porosity, permeability and water saturation.

摘要： Plural of virtual curved surface solids, each of which is a curved surface solid formed by a combination of plural of virtual spheres, is placed so as to fill in space voxels, referring to porous-body data in which positional information is associated with voxel-type information (step S100). Information regarding a flow rate for each space voxel when a fluid passes through a porous body is derived by executing a fluid analysis based on the porous-body data (step S110). A flow-rate-weighted mean diameter Ru, which is a weighted average obtained by weighting an equivalent diameter R' i for each virtual curved surface solid with a volume V i and an average flow rate U i for each virtual curved surface solid, is derived based on information regarding the virtual curved surface solids and information regarding the flow rate for each space voxel (step S120).

摘要： The effect of a treatment on a rock sample or sub-sample extracted from the rock sample can be analyzed through computed tomography (CT). To determine the effect of a treatment of a rock sample or the sub-sample, pre-treatment and post-treatment CT images of the rock sample or the sub-sample are captured. Further, the pre-treatment CT images and post-treatment CT images of the rock sample or the sub-sample are compared based on one or more alignment markers added to the rock sample or the sub-sample. In some embodiments, pre-treatment and post-treatment CT scans of an extracted sub-sample provide higher-resolution information regarding the effect of the treatment. Further, pre-treatment and post-treatment CT scans of a rock sample with a restored sub-sample may be considered and may provide additional information regarding the effect of the treatment on the rock sample or the sub-sample.

摘要： A method for estimating permeability properties of a porous material from a sample thereof includes making a three dimensional tomographic image of the sample of the material. The image is segmented into pixels each representing pore space or rock grains. The image is divided into sub-volumes. A porosity is estimated for each sub-volume. The components of a permeability tensor are determined by conducting simulations. Principal permeability values and directions are then calculated. The permeability properties are stored in a computer or displayed.
