碳酸盐岩的岩相识别方法及系统
摘要：
本发明提供一种碳酸盐岩的岩相识别方法及系统。该碳酸盐岩的岩相识别方法包括：获取碳酸盐岩的彩色图像；根据碳酸盐岩的彩色图像得到碳酸盐岩的灰度图像；根据碳酸盐岩的灰度图像得到碳酸盐岩的二值图像；根据二值图像的像素值确定二值图像中的黑色像素；根据黑色像素在二值图像中纵向个数的平均值，以及黑色像素在二值图像中横向个数的平均值，得到岩石构造数；根据岩石构造数识别碳酸盐岩的岩相，可以准确识别碳酸盐岩的岩相，提高识别工作效率。
摘要（英）：

The invention provides a lithofacies identification method and a lithofacies identification system of a carbonate rock. The lithofacies identification method of the carbonate rock comprises the following steps of obtaining a color image of the carbonate rock; according to the color image of carbonate rock, obtaining the gray image of carbonate rock; according to the gray image of carbonate rock, obtaining the binary image of carbonate rock; determining black pixels in the binary image according to pixel values of the binary image; according to the average value of the number of black pixels inthe binary image and the average value of the number of black pixels in the binary image, obtaining the rock structure number. The identification of carbonate rock facies according to rock structurenumber can accurately identify carbonate rock facies and improve the identification efficiency.
