卡塔爾的石油還能開采23年。ZT維基的Economy of Qatar。。。

Petroleum is the cornerstone of Qatar's economy and accounts for more than 70% of total government revenue, more than 60% of gross domestic product, and roughly 85% of export earnings. Proved oil reserves of 15 billion barrels (588,000,000 m179;) should ensure continued output at current levels for 23 years. Oil has given Qatar a per capita GDP that ranks among the highest in the world. Qatar's proved reserves of natural gas exceed 7000 km179;, more than 5% of the world total, third largest in the world. Production and export of natural gas are becoming increasingly important. Long-term goals feature the development of off-shore petroleum and the diversification of the economy.

Qatar is now the richest country in the Muslim world. Current GDP per capita registered a world record-breaking peak growth of 1,156% in the Seventies. This became quickly unsustainable and Qatar's current GDP per capita contracted 53% in the Eighties. But rising global oil demand helped current GDP per capita to expand 94% in the Nineties. Diversification is still a long-term issue for this over-exposed economy.
