Minhe basin, located in the boundary between Gansu and Qinghai, abounds in oilgas resources through over 70-year’s exploration. However, the study and exploration is still at a low level. This paper lists lots of oil evidences in surface in field, and carries out a study on oil reservoir in two oilfields with results of oil 3.02×10⁸ t and gas 493.83×10⁸ m³ through basin simulation. This basin, of big oil-gas potential, is one of favorable oil-gas basins to be developed. It is recommended for government and oil-gas companies to do more studies and to invest more in Minhe basin. And these two discovered oilfields shall be submitted to National Reserve Committee with explored reserve and shall be put into operation.

As China moves towards the heavy industrialization, a huge demand of iron ores has been triggered in domestic markets. So far China’s iron ore import depends heavily upon three countries, and the global iron ore export markets have been monopolized, leading to a loss in negotiation rights in international iron ore markets. China is always in a passive status in iron ore trade which jeopardizes domestic economy. This paper analyzes the causes of price rise in importing iron ores and of losing rights to be rater, and presents approaches to the unfavorable situations.

Large oil-gas fields with over 100 million tons of yield have been recently discovered in volcanic rocks in Songliao basin and Dzungaria basin. This paper, based on the geology and distribution of oil-gas reservoir in volcanic rocks, analyzes the status of oil-gas resources hosted in volcanic rocks, forecasts the prospect in some blocks to be discovered. It concludes that volcanic-hosted oil-gas reservoir is of great prospect to be explored as a new vital field in the future.

The traditional petroleum theory is helpful to search oil in sedimentary rocks. However, as oil-gas exploration has been intensively concentrated on sedimentary regions, the oil-bearing sedimentary regions become less and less. To look for oil in non-sedimentary areas caught more and more attention. This paper analyzes the oil-gas potential in the volcanic rocks worldwide, and studies the oil-gas reservoir formation conditions of volcanic rocks in basins. The volcanic-hosted oil-gas reservoir is normally located at the lower sequences, where with a low exploration but high potential shall be a new vital oil-gas exploration area. Some volcanic basins in circumPacific, Mediterranean sea and middle Asia are of good oil-gas reservoir-forming conditions, where can become the major areas for volcanic-hosted oil-gas.

A sharp falling in oil price and a lack in circulating fund, during a deteriorating financial crisis, impacts the foreign oil companies with high debts, even engenders difficulties in some oil production countries with single industrial structure, at the same time, brings some opportunities for Chinese enterprises to enter foreign markets and to acquire foreign assets. This paper, based on an analysis of the past economic crisis, presents a national strategy for oil-gas that Chinese oil companies acquire foreign oil-gas exploration blocks with strong competitiveness in human resources, capital, technology and geographic politics.
