摘　　要：陕北斜坡带是鄂尔多斯盆地石油分布的主要地区,其特点是构造平缓,油藏分布集中。其中三叠系延长组的长6油层组作为主力油藏之一,一直以来都是关注和研究的热点。前人对长6油藏的成藏条件及特征都有一定的研究和认识。但是随着开发程度的不断提高和深入,研究发现长6油层组内部油藏的特征和分布具有一定的差异性和随机性。因此,通过对X油田的长6内部油藏特征及分布规律的对比分析,对其分布的不均一性进行了解和认识。The North Shanxi 3lope Lone is the maul a ture, reservoir distribution mainly concentrates. The Chang 6 reservoir of Yanchang formation is one of the main reservoirs, which gets a lot of attention and research. The predecessor to the Chang 6 reservoir forming conditions and characteristics are researched. But with the continuous improvement and development degree, research finds that the characteristics and distribution of Chang 6 formation in North Slope of internal reservoir is not the same, have some differences and randomness. Therefore, this paper mainly through the analysis comparison of X oilfield in Chang 6 reservoir characteristics and distribution of internal law, understands Chang 6 internal reservoir in the North Shaanxi Slope heterogeneity.
