| 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 largescale 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. |
