摘　　要：鄂尔多斯盆地白豹－华池地区为长庆油田主要上产区块之一，该区长6含油层系为一套水下滑塌浊流沉积产物。对该套浊积岩的电成像测井特征进行了分析，进一步探讨了该区长6浊积岩－电成像测井反映出的岩石结构特征、裂缝发育情况与产油量的关系；在对浊积水道古水流的研究基础之上，分析了该地区的物源；在对该套浊积岩下伏地层产状分析基础上，论述了该套浊积岩沉积时的古地形。为该地区石油勘探开发提供了有力的技术支撑。Baibao-Huaehi region of Ordos Basin is one of main blocks for Changqing Oilfield to increase the production. The oil-bearing series of Chang6 in this region is a set of products of underwater slump turbidite deposition. This paper analyzes characteristics of the electrical imaging logging （ELL） of this set of turbidite, further investigates the rock＇s structural characteristics that was reflected by EIL of the Chang6 turbidite, the relationship between fiacture development conditions and oil production. The source rock of the region is analyzed on the basis of studying the paleo-water-flow in the turbidite channel. The paleo-topography when the turbidite deposited is discussed on the basis of analyzing the occurrence of the underlying formalion of this set of turbidite. The above studies provide strong technical support for oil exploration and development of the region,
