摘要
生油层、储集层、盖层、运移通道、圈闭以及保存条件在圈闭成藏过程中的重要性各不相同,可用层次分析法对它们在圈闭成藏过程中的重要性进行定量分析研究.为了客观地评价圈闭成藏条件,以盐城凹陷为例,利用层次分析法,结合实际地质资料,建立了该区圈闭评价的地质模型,对该区的各构造圈闭进行了综合评价.结果表明:朱家墩圈闭最有利(已钻探),黄尖圈闭较有利,新洋圈闭中等偏差,这与实际勘探结果相吻合.优选出有利圈闭(黄尖圈闭)进行下一步井位钻探.实例证实利用层次分析法建立地质模型对圈闭成藏进行定量评价是切实可行的.
The conditions of source layer,reservoir bed,caprock,migration,trapping and preservation play a different role in the course of hydrocarbon reservoir formation.The gradual layer analytical method is to analyze quantitatively their respective importance in the formation of reservoirs.Using the gradual layer analytical method in each structural trap of Yancheng Depression,the geological model has been established.Applying the geological model in the prospect assessment in Yancheng Depression,the result shows that Zhujiadun trap is the best,Huangjian trap is better and Xinyang trap is poor.It proves that using the gradual layer analytical method to set up the geological model and evaluate trapping quantitatively is effective.
