泥质含量是反映储层岩性、物性的重要参数,它是精确求取其它物性参数的基础,同时也是进行地球物理正演的必要参数。提高泥质含量的计算精度是精确的刻画储层的一项困难而又重要的研究。通过对常见砂泥岩中泥质含量求取方法进行了总结,讨论了每种方法的适用性及其优缺点。 The shale content is an important parameter that reflects the lithology and physical properties of the reservoir. It is the basis for accurately finding other physical parameters and is also a necessary parameter for geophysical forward modeling. The calculation accuracy of shale content is a difficult and important study to accurately describe the reservoir. The method of determining the content of shale in common sand and mudstone is summarized, the applicability of each method and its advantages and disadvantages are discussed.
