Abstract:

The methods for analyzing economic characteristics of petroleum resources and the technical procedures to estimate the size of economic petroleum resources were discussed.A computational model was presented to calculate the economic coefficient of petroleum resources that can be enumerated by diagram data.The statistical analysis on data of Songliao Basin and Ordos Basin shows that the economic coefficient is directly proportional to resource abundance.The economic coefficients and resource abundance of calibrated area were calculated,and a diagram of economic coefficients was established.The application way and limit of the diagram were also illustrated.A case history was given to explain the usage of the diagram to estimate the size of economic petroleum resources.

Key words: oil and gas resources, economic evaluation, economic coefficient, assessment model, diagram

摘要：

介绍了油气资源经济性的分析方法和估算油气经济资源规模的技术路线.提出了油气资源经济系数的计算模型,并用图表数据列举了经济系数的求取方法.对松辽盆地和鄂尔多斯盆地数据进行了统计分析,确定了油气资源经济系数与资源丰度之间存在的正比关系.通过对刻度区的经济系数、资源丰度的计算,建立了油气资源经济系数图版,并解释了该图版的使用方法和适用范围.用实例介绍了运用该图版估算油气经济资源规模的方法.
