埕岛油田馆上段储层非均质性研究

THE STUDY OF THE RESERVOIR ANISOTROPY IN THE UPPER GUANTAO FORMATION IN CHENGDAO OIL FIELD

通过对我国第一个浅海 极浅海特大油田—埕岛油田馆上段储层层内韵律性、层间差异性、平面上砂体连续性、层间层内隔夹层的定量评价以及储层微观孔隙结构的研究 ,揭示了埕岛油田馆上段储层宏观、微观非均质特征 ,指出埕岛油田馆上段储层平面非均质性与微相带、砂体发育密切相关 ,并建立了埕岛油田馆上段储层四种类型的孔隙结构模式 。

Based on the analyzing of the internal rhythmicity, interlayer differences, sandbody continuity in plane, quantity evaluation of interlayer and micro pore structures of the reservoir in the upper Guantao formation (Ng)in Chengdao oil field, the first very large oil field in shallow very shallow sea of China. The macro and micro anisotropy of Ng has been studied. The result indicates there is close relation with micro facies and the development of the sand bodies. Four types of Pore structure model of this formation has also been built, which is very useful for the development and adjustment of Ng oil pools of this oil field.
