油气储量可升级性评价方法探讨

以油气预测储量区块为研究对象,提出利用升级难易程度指数值定量评价储量可升级性。研究认为,影响预测储量升级性的主要因素是储量品位,其他因素对储量升级性有影响,但影响程度相对较小。预测储量升级性可采用对主评因素、辅评(背景)因素、关联因素的因子赋值方法进行升级难易程度指数值计算,利用指数值大小确定可升级性及升级顺序。

Probing into the Methods for Oil-Gas Reserves Upgradability Evaluation

Regarding an oil-gas predicted reserves block as the object of study, the article puts forward the quantitative evaluation of reserves upgradability by using the index of the degree of upgrading ease and difficulty. The research considers that the main factor influencing predicted reserves upgradability is reserves grade, other factors also have influence upon reserves upgradability, but their degree of influence is relatively small. Predicted reserves upgradability can be acquired through calculating the index of the degree of upgrading ease and difficulty by using the factor assignment method being aimed at main evaluation factors, auxiliary evaluation （background） factors and correlation factors, upgradability and upgrading sequence can be ascertained by the number of the index.
