鄂尔多斯康台区6油层储层分布规律及主控因素分析

Analysis on distribution rule and main controlling factors of Chang-6 reservoir in Ordos Kangtai area

鄂尔多斯盆地中生界三叠系延长组长6油藏是典型的岩性油藏,该区域的油藏特点是连通性差,非均质性强。通过对康台区长6油藏的分布规律进行研究分析发现,该区域的油藏分布主要受油源、沉积相以及储层物性等多方面共同影响。本文主要对康台区长6油层储层分布的规律进行研究分析,寻找低渗透储层中有利于高效储层的控制因素,为油藏的开发提供有利的地质条件。

The Chang6reservoir of Mesozoic-Triassic Yanchang Formation in Ordos Basin is a typical lithologic reservoir,and poor connectivity and great heterogeneity are the typical characteristics of this area.Based on the analysis of the distribution rule of Chang6reservoir,this paper finds that the reservoir distribution in this area is mainly affected by oil source,sedimentary facies and reservoir physical properties.This paper mainly researches the distribution rule of the Chang-6reservoir in the Kangtai area,and finds out the controlling factors favorable for the high efficient reservoir in the low permeability reservoir with the hope to provide favorable geological conditions for the reservoir development.
