Preface:Special Topics on Ultra-deep Oil and Gas Exploration
文献摘要：
The term'ultra-deep layers'refers to those sedimentary formations which are currently,or have been,buried at depths exceeding 6000 m.China has continuously achieved major oil and gas breakthroughs in marine ultra-deep exploration,significantly promoting the strategic level of ultra-deep oil and gas resources over recent years.The ultra-deep formations of the cratonic basins in China are predominantly constrained to Precambrian to lower Paleozoic marine stratigraphy.These layers are demonstrably of ancient strata that have experienced high degrees of thermal evolution,as indicated by complex oil and gas generation and accumulation processes.Consequently,the exploration difficulties of these areas are huge.To explore the oil and gas resources enriched in the ultra-deep layers of the Tarim and Sichuan basins in China,as well as to uncover their entangled growth processes and multiple controlling factors,it is urgently required that comprehensive research from the perspectives of hydrocarbon generation,migration and accumulation be conducted.This will be of great importance in providing scientific guidance for future oil and gas exploration in ultra-deep layers.
