This book analyzes the formation and evolution of the giant hydrocarbon
reservoirs based on major basins onshore China. It discusses exploration
and research advantages of major basins in China, such as Sichuan,
Tarim, and Ordos Basins and also systematically analyzes and summarizes
the formation conditions, distribution rules, and main controlling
factors of deep oil and gas fields. On this basis, it forecasts the
exploration prospect of China's onshore deep oil and gas, providing
theoretical guidance and technical support for deep oil and gas
exploration breakthrough and large-scale reserves growth. This book
focuses on the analysis and discussion of hydrocarbon generation
mechanism of deep-paleo source rocks, discusses the accumulation rules
of cross-structural reservoir formation and oil-gas enrichment in
ancient strata, the combination of gypsum-salt rocks and carbonate
rocks, the potential of oil and gas accumulation under salt, the main
controlling factors and distribution rules of deep oil and gas fields,
and preliminarily grasps the geological understanding of the formation
and distribution of deep-large oil and gas fields, namely ①abundant
hydrocarbon supplied by two types of source kitchens, ②three large-scale
lithologic reservoir rocks, ③hydrocarbon accumulation controlled by
three paleoes (paleouplift, paleoplatform margin, and paleofaults), and
④reservoir formation across major tectonic periods. The book serves as a
guidance for both researchers and students majoring in petroleum geology
and other related fields.
