This work presents a novel algorithm that achieves enhanced resolution of well logging signals, e.g., from 1 ft of a pulsed neutron mineralogy tool to 0.04 ft of an imaging tool. The algorithm, denoted as “Digital Core,” combines mineralogical and sedimentological information to generate a high-resolution record of the formation mineralogy which can be consequently applied to thin bedded environments. The keystone to the philosophy of this algorithm is that the spectral information recorded by mineralogy tool is a weighted average of the mineralogy of each lithological component in the analyzed volume. Therefore, by using a high-resolution image log to determine the proportion of each lithological component, their composition can be determined from the mineralogy log data. A field case from a well located in South Australia is presented in this work, and the results validate the feasibility of an integrated core-level petrophysical analysis in a cost-effective and timely manner compared to conventional core measurements.

一种新的解释算法的开发与验证，以提高测井信号的分辨率

这项工作提出了一种新颖的算法，可以提高测井信号的分辨率，例如，从1英尺的脉冲中子矿物学工具到0.04英尺的成像工具。该算法称为“数字岩心”，结合了矿物学和沉积学信息，以生成高分辨率的地层矿物学记录，因此可以应用于薄层环境。该算法原理的重点是矿物学工具记录的光谱信息是所分析体积中每种岩性组分的矿物学的加权平均值。因此，通过使用高分辨率图像测井仪确定每种岩性组分的比例，可以根据矿物学测井仪数据确定其组成。
