摘要

摘要: 综合运用辽河西部凹陷齐9—欢50区块油藏静、动态资料,建立了杜家台油层储层层内、层间及平面3个层次的宏观非均质模式,揭示出扇三角洲前缘低渗透储层剩余油的分布规律.研究表明,该储层宏观非均质性强,层内剩余油主要富集在正韵律砂体的上部和复合韵律砂体的低渗透、强非均质部位;平面剩余油主要分布在扇三角洲水下分支河道砂体边缘、连通性差或分布局限的砂体内;层间剩余油富集程度与纵向上层间旋回性基本一致,在物性差、非均质性相对强的层位富集.研究认为宏观非均质性控制平面和垂向剩余油的形成与分布.

Abstract: Three macro-heterogeneity models of reservoir,interbedded,intraformational and planar,has been established for the Dujiatai reservoirs in Qi 9-Huan 50 Block in the West Liaohe Depression based on the dynamic and static data.And the distribution principle of remaining oil for low permeability(reservoirs) in the front of fan delta facies has been revealed.Moreover,the effect of macro-heterogeneity on forming and distribution of remaining oil has been discussed.Research shows that the macro-heterogeneity of this set of reservoir beds is apparent,that the vertical distribution of remaining oil within oil zones is controlled by interbedded and intraformational anisotropism and that the planar distribution is controlled by planar and intraformational anisotropism.
