鄂尔多斯盆地刘台区长6储层非均质性分析

Analysis of heterogeneity of Chang 6 reservoir of Liutai oilfield in Ordos basin

本文利用研究区长6油层组90余口井的岩心观察、测试以及测井资料,对该区长6油层组长61-1、长61-2、长62-1和长62-2四个小层的储层非均质性进行了研究,结果表明,长6油层组各小层层内和层间非均质性整体较强,平面非均质性较弱。

This paper studies the reservoir heterogeneity of Chang61-1,Chang61-2,Chang62-1 and Chang62-2 small layer belonging to Chang 6 reservoir group by the data of core observation,testing and well logging on more than 90 wells of Chang 6 reservoir group.The results show that the intra-layer and interlayer heterogeneity of each layer in Chang 6 reservoir group is strong on the whole,and the plane heterogeneity of each layer is weak.
