Giant carbonate oil and gas fields:global distribution and new exploration frontiers
摘要
Abstract
Carbonate oil and gas fields represent a significant component of global hydrocarbon resources,accounting for over 60%of the total conventional reserves.This paper systematically reviews the distribution characteristics of giant carbonate oil and gas fields worldwide.Through analysis of typical fields,it summarizes the primary controlling factors for hydrocarbon accumulation and identifies new frontiers for exploration.The results indicate that these giant fields are predominantly located in regions such as the Persian Gulf Basin in the Middle East,the Pre-Caspian Basin in Central Asia,the Permian Basin in North America,and the Santos Basin in Brazil,with reservoir ages ranging primarily from the Mesozoic to Cenozoic.The key factors controlling hydrocarbon accumulation include:(1)sedimentary background,which determines the scale of source-reservoir-cap rock systems;(2)tectonic and diagenetic modifications,which create large-scale reservoirs;(3)tectonic stability and seal integrity,which are crucial for reservoir preservation.Future exploration should focus on new frontiers such as ultra-deep formations,deep-water environments,complex tectonic zones,and unconventional carbonate reservoirs,which are expected to become vital successors for future resource supply.关键词
