1. Prediction of China's oil and gas demand There exist many research results about the prediction of China's oil and gas demand. In view of a long-term demand prediction, we should consider such a prediction comprehensively from two aspects. It means that a better prediction can be obtained by coordinately taking into account the prediction method based on the demand for individual oil and gas products, and the method for predicting the total demand.1.1 Prediction based on demand for individ… 相似文献

In 2012,China's net import of crude was 268.7 million tons,which is 18.63 million tons higher than that of the previous year.Net import of refined products increased greatly as the naphtha import climbed up and gasoline and diesel import shrank.Net LPG import had been reduced gradually for the third year and the sharp rise of petroleum coke import lifted the net imports of other relevant products by 50%.The total net import of crude,refined products,liquefied gas and other products was increased by 7.9%,reaching 293.1 million tons.The share of imported petroleum on the nation's total oil product consumption was raised from 59.9% in 2011 to 62.1% (Fig 1). 相似文献

Chinese overseas oil and gas investment and cooperation had entered a more advanced stage of internationalization after more than 20 years of growth and expansion. Its national oil and gas companies had been shifting from resource-oriented entities to internationalized state-owned companies aiming at investing and profiting. During the process, the companies had been facing more challenges in increasing their commercial value and improving their ability to run business overseas. 相似文献

The world is rich in offshore oil and gas resources. The offshore oil reserves account for about 34 percent of the world's total. With a 30 percent proven rate, offshore oil exploration is still in its preliminary stage. Based on the statistics by "Oil & Gas Journal," as of the January 1, 2006, the proven oil reserves worldwide are 175.7 billion tons and the proven natural gas reserves 173 trillion cubic meters. The global offshore oil reserves approach 135 billion tons, of which 38 billion tons are proven, while the offshore natural gas reserves amount to about 140 trillion cubic meters, of which 40 trillion cubic meters are proven. 相似文献

1.Introduction Russia is one of the countries with rich reserves of crude oil and natural gas. Among the petroleum-producer countries, Russia ranks the eighth with its proven remaining recoverable oil of 8.219 billion tons and the first with its proven remaining recoverable natural gas of 47.57 trillion m3 (Oil and Gas Journal, 2005). In today’s economic globalization, the whole world will greatly benefit from Russia’s rich oil and gas resources and its opening policy in petroleum industry… 相似文献
