本文根据裂缝性储层油气成藏的特殊性,提出一种新的裂缝型油气资源评价模拟系统.它是从裂缝系统控制油气藏出发,基于压降法储量分布和油气藏数分布,通过有序统计和匹配法,预测勘探层的油气藏数及各油气藏的油气量,由此估算勘探层资源总量,并根据未发现油气藏的油气量求得勘探层潜量.

The authors of this Paper set up a modelling system for resource assessment of oil and gas for fracture-typed reservoir,fousing on the specialities of such a type of oil-gas pool formation.In a view of fracture system controlled occurrence of oil-gas pools,the authors predicted the number of pools in an exploratory play as well as the oil and gas reserves in each pool,based on the distributions of reserves calculated by pressure falling and the number of oil/gas pools,using ordered statistic and matched methods.Additionally,with what mentioned above,the total resources are evaluated;consequently,in an exploratory play,the potentials depending upon the amount of oil and gas in undiscovered pools are predicted.
