中国边缘海盆地构造演化与油气分布富集规律
Characteristics of Tectonic Evolution and Distribution and Enrichment Patterns of Oil and Gas in the Chinese Marginal Basin
摘要
Abstract
The Chinese marginal basin is located at the most active Cenozoic era,which is formed by the interaction of Eurasia, India-Australia and the Pacific plates,and its southern marginal basin is still subjected to the impact of the South China Sea cracking and expansion and many other factors,so the rift-depression double-layer structure basins have formed,which have different types,such as extensional or composite strike-slip-extrusion type. The sedimentation has filled in the basin,which is mid-deep lake face strata and hydrocarbon source rocks in the early phase of the Paleogene rift Valley,coal-bearing strata and hydrocarbon source rocks in the late phase of the Paleogene rift,and marine strata and hydrocarbon source rocks in the Neogene depression,which has laid a foundation for oil and gas formation. Due to the impact of the regional geological setting, the characteristics and thickness of the marginal basin crust has gradually graded features from the continental margin area to the deep ocean basin area. The basin subsidence deposition center has gradually migrated to the deep ocean basin,which results in the terrestrial heat flow and geothermal field increasing gradually to the ocean basin,coupled with the space-time mutual coupling configuration between advanced new tectonic movement and source supply system,which ultimately controls and restricts the law of oil and gas distribution and enrichment in marginal basin.关键词
