This book analyzes hydrocarbon generation and accumulation within space-limited source rocks. The authors draw conclusions based on the principles of basin formation, hydrocarbon generation and accumulation, coupled with the practice of terrigenous basins in eastern China. Hydrocarbon generation and expulsion have been quantitatively assessed in space-limited source rock systems. This book explores new hydrocarbon generation and expulsion models to reflect real geological situations more accurately. The theory and practice proposed in this book challenge the traditional theory of kerogen thermal degradation and hydrocarbon generation.

Guided by organic geochemical methodologies, this book conducts a comparative analysis of the characteristics of oil source rocks deposited across various geological eras within typical continental oil-bearing basins, revisits several issues concerning the oil generation theory of continental oil source rocks, and reshapes organic geochemical thinking methods and simulation experimental techniques, challenging the traditionally dominant "artificial petroleum" theory and experimental techniques. The book is divided into three parts: "Introduction," "Characteristics of Oil Source Rocks in Typical Continental Oil-Bearing Basins in China," and "Simulation Experiments on Oil Generation of Continental Oil Source Rocks," encompassing a total of 12 chapters and 143 figures. It delves into the petroleum geological evolution during the stages of continuous subsidence, overall uplift and denudation, and full shrinkage in major basins such as the Junggar, Ordos, Sichuan, Songliao, and Bohai Bay. The book analyzes the characteristics of the main oil source rocks, develops an oil generation simulation instrument for continental oil source rocks, establishes the experimental technology for low-temperature catalytic cracking of source rocks to simulate oil generation, and reveals the oil generation mechanism of the "geological molecular sieve" and favorable conditions for oil generation in source rocks. It offers new ideas and methods for the evaluation of petroleum resources in continental oil-bearing basins and can be a reference for researchers engaged in petroleum geological and geochemical research, as well as teachers and students working in related fields.
