Abstract:

The oil accumulation parameters of 40 oil plays in 8 basins of China were analyzed.27 parameters sorted in 5 groups,such as oil source,reservoir,trapping,preservation and matching relation,were selected and used for the assessment of plays.According to the statistic distribution of each parameter derived from the above 40 plays,the value of each parameter was graded into 4 levels,named as the best,good,fair and poor taken as a score of 4,3,2 and 1 respectively.The influence factors of 40 plays were analyzed,according to the scores of 27 parameters of each play.The result shows that 6 parameters among the above parameters were considered as the unimportant or being related with other parameters.The final 21 parameters were used in the assessment of oil play.

Key words: oil and gas resource assessment, petroleum accumulation parameter, assessment parameters, grade standard, play

摘要：

根据我国陆上八大盆地40余个区带成藏条件的解剖结果,提取了油气成藏条件中的油气源条件、储集条件、圈闭条件、保存条件和配套条件参数共27项,对上述参数在中国盆地中分布特征进行了统计分析,对每一项参数的取值进行了等级划分,确定了每一项参数的分级界限,以40个区带作为统计样本,进行了因子分析,剔除初选参数中对油气成藏影响不显着或与其他参数相关的变量,最终确定了包括21项参数的区带地质评价参数体系和参数分级标准.
