Abstract
The Persian Gulf Basin is located at the junction of the Eurasian Plate and the Arabian Plate. It is mainly developed on the Arabian Plate and belongs to a large foreland sedimentary basin. The Persian Gulf Basin is extremely rich in oil and gas resources. As of 2012, more than 1,260 oil and gas fields have been discovered in the Persian Gulf Basin, with a total recoverable reserves of 221.58 billion tons of oil equivalent, accounting for 38% of the global recoverable reserves of oil and gas. The Persian Gulf Basin can be further subdivided into 7 sub-basins, namely Zagros Basin, Victoria Mesopotamia Basin, West Arabia Basin, Central Arabia Basin, Rub Al Khali Basin, Oman Basin and Mali. The Bouchabwa Basin, each basin is a large oil and gas area. Based on the analysis of paleogeographic evolution, source rocks, reservoirs, caprocks, and accumulation processes and models of secondary basins, it is believed that the Persian Gulf Basin has an excellent geological background, a flawless accumulation combination, and long-term stable. The tectonic environment has accepted the huge thick deposits with absolute marine dominance and almost no sedimentary discontinuities. The source rocks rich in organic matter deposited in the marine subtropical basin can be preserved in the reducing environment. Good physical properties, usually thick reservoir rock (mainly carbonate rock, followed by sandstone) and effective caprock area are widely distributed. There are many huge and widely distributed anticline structures, which can capture oil and gas from mature source rocks in time to enrich and accumulate. At the same time, due to the injection of oil and gas, the diagenesis of the reservoir is stopped, so that most of its pore space is preserved. The Persian Gulf Basin has developed very favorable conditions for oil and gas accumulation, and large oil and gas reservoirs are well preserved.KeywordsPersian Gulf BasinCarbonate rockAccumulation combinationAccumulation rule
