| 摘 要： | 在石油勘探工程中,储层孔隙度是进行油气预测、油气储量计算的重要参数。根据测井铸体薄片图像资料,在传统BP网络模型的基础上提出了一种基于灰色关联约束的BP神经网络改进模型。对铸体薄片图像进行孔隙识别、统计,进而自动判读储层孔隙度。研究和实验表明,该方法对储层孔隙度的分析、判读更具合理性和实用性。

| Abstract: | In the area of the oil exploration engineering,the reservoir porosity is important parameters to forecast and calculate the oil and gas.In terms of the casting sheet images,this paper presented a BP neural networks pattern based on grey relationship,then used it to analysis and identify the pore and to calculate the reservoir porosity automatically.The research and experiments showed that the method was more reasonable and practical to analysis and calculate the reservoir porosity. |
