Features: This book takes mudstone and shale as the research subjects, based on the theory of organic clay chemistry, employing different treatment methods and analytical techniques to explore the interactions between organic matter and clay minerals in mudstone and shale, the preservation types and modes of organic matter, as well as the hydrocarbon and water expulsion characteristics of different types of organic matter. Although organic matter and clay minerals are closely associated in nature, forming an organic whole, they can be classified into three types: interlayer organic matter of clay minerals, polymeric organic matter, and biogenic organic matter. Among these, interlayer organic matter of clay minerals and polymeric organic matter primarily preserve dissolved organic matter, which is of great significance for in-depth studies on the accumulation, deposition, and preservation of organic matter, especially for researching the carbon cycle. The differences in organic matter and clay mineral types and properties in mudstone and shale determine the complexity of their interactions and binding, as well as the variations in hydrocarbon expulsion characteristics. This has important implications for understanding the generation of hydrocarbons, oil and gas reservoir formation, and the calculation of oil and gas resources. This book serves as a reference for professionals, researchers, and students in fields such as petroleum geology, geochemistry, oil and gas exploration, oil production and oilfield development, marine geology, environmental protection, and soil science.
