吐哈盆地台北西部低阻油层赋存的宏观地质背景及分布特征

The general geological background and distribution character of low resistivity oil bed in the west of Tuha basin taibei area

吐哈盆地台北西部低阻油层存在成因多样、剖面分布跨度大、平面分布广、识别难度大的特点。依据大量的岩石物理资料,开展了低阻油层影响因素分析。文章阐述了西部低阻油藏赋存的四种宏观地质背景,并针对于每一种低阻油层系统分析介绍了其分布特征。该研究成果为开展分类评价低阻油层奠定了基础。

The low resistivity oil bed of the west of Taibei area in the Tuha basin is described with the following characters,the formative result of the bed attributes to many reasons;the profile of bed extend in a long range;the distribution in the area is very large;and the identification of the bed is difficulty.Based on the data of rock physical characters,the analysis of the affecting facters on the low resistivity oil bed is developed.Four types of general geological background of the low resisitivity oil bed are discussed in the paper.The distribution character of the bed is also analysed for every bed.The study result is based for evaluating different types of low resisitivity oil bed.
