| 摘 要： | 曹崾岘位于鄂尔多斯盆地陕北斜坡中部,其主力油层为侏罗系延安组延9油层组。根据大量的岩芯观察及测井曲线分析,认为曹崾岘地区延9期主要发育曲流河相。根据沉积层序特征,可将该区曲流河相细分为河道、决口扇、天然堤、河漫滩沉积微相。其中河道微相砂体最为发育,是该区延9的有利储层,河道砂体是该区今后勘探的方向。

| Abstract: | Caoyaoxian is located in central area of Shanbei slope in Ordos basin.Major reservoir is the Jurassic Yan'an 9 formation.According to observation of a large number of cores and well log analysis,the Caoyaoxian Yan 9 formation is mainly considered to develop river facies.According to sedimentary sequence features,the river facies in this area can be sub-divided into channel deposit,natural levee,crevasse splay deposit,flood plain deposit.The channel deposit is a good reservoir,and also is the direction of de... |
