The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
A method and process for lithological classification of shale oil reservoirs based on RGB fusion of well logging information
PendingCN122307774AShale oil and gasResistivity logging
This invention relates to a method and process for shale oil reservoir lithofacies classification based on RGB fusion of well logging information. The method uses the first derivative of the reflection coefficient curve to divide rock units. For each rock unit, lithological indices are calculated using the root mean square of natural gamma logging, sedimentary structural indices are calculated using the roughness of resistivity logging curves, and oil-bearing indices are calculated using the root mean square of resistivity curves. The RGB color model is used to perform parameter fusion and color representation of the lithological, sedimentary structural, and oil-bearing indices of the shale reservoir. Different types of lithofacies color templates established using core sections are used to identify the lithofacies types of shale oil and gas reservoirs throughout the well section. This method achieves three-parameter fusion identification of shale reservoir lithofacies types, which is more intuitive and convenient.
