With ′99 list of crude oil balancing in provinces and current trade and transport information of crude oil,this paper analyses the spatial structure of crude oil flow,the characteristic of its flow field and the form of its flow track in China.

Discussion on Oil-resources-driven Economic Modernization in Saudi Arabia (1932—1990);

Comparative study on the typical classification of petroleum resources;

The predicted petroleum resources in place of Ordovician in Tahe oilfield amount to about 1.

On the foundation of analyzing mathematical principle,mathematical model,parameter feature and application condition,petroleum resources in the Qianjiang Sa.

It is urgent that oil resource should be used in an efficient way.

We heavily rely on oil resources from foreign countries.

This paper analyzes on the distribution situation,production condition and existing problems of Chinese petroleum resource,and advances some countermeasures for the safe supply of Chinese petroleum resource.

On the basis of it,we introduce the theory method and mathematic model of the petroleum resource value.

The gap of supply and demand of Chinese petroleum resources and dependence on foreign resources have increased year by year,and the same with resource risks caused thereby.

In value assessment of oil reserves, the cost differential factors that are mainly discussed consist of four factors, of which the investment cost differential factor takes the first place in the discussion.

In value assessment of oil reserves, the cost differential factors that are mainly discussed consist of four factors, one of which is a relatively external factor for the oil reserves proper, thus called external cost differential factor.

In value assessment of oil reserves, the cost differential factors that are mainly discussed consist of four factors, of which the transportation cost differential factor is an important one.
