摘　　要：鄂尔多斯盆地位于我国中部,也被称之为陕甘宁盆地,是我国的第二大盆地。自古以来,鄂尔多斯地区地台一直都较为稳定,但从其发展中期起,鄂尔多斯盆地开始出现沉降现象,并逐步走入大型克拉通内陆坳陷带晚期,逐渐开始向海陆过渡沉积。鄂尔多斯盆地演化过程中,其有沉积到构造,沉积阶段的不同以及各具特点的构造特点,也就造就了其不同的油气生成、运移以及聚集等含油气风格,鄂尔多斯盆地三大含油气系统逐渐形成。本文就鄂尔多斯盆地镇泾区块长8油藏油层优选进行研究,在对其区域地质特征和长8油层录井显示特征进行分析的基础上,对长8油层录井标准进行深入探讨,希望能够为长8油藏油层优选带来一定参考建议。Ordos Basin is located in the middle of China, which is also known as Shan-Gan-Ning basin, and it is the second largest basinin China.Since the ancient times, the platform in Ordos region has been relatively stable, but since its medium-term of development, the settlementphenomenon in Ordos Basin began to appear, and gradually it came to the late period of large intracratonic sag zone,besides gradually began todeposit in sea-land transition zone. In the process of Ordos Basin evolution, it changed from deposition to the structure,and the differences in depositionperiod and the structure characteristics also contributed to the generation, migration and accumulation of different oils and gases, finally the threemain petroleum-gas system of Ordos Basin gradually formed.In this paper, it takes analysis of the oil reservoirs optimization of Chang 8 reservoirand layer of Zhenjing Block in Ordos Basin,and on the basis of analyzing the geological features in this regional and the characteristics of Chang8 reservoir logging display,it take further discussion on of Chang 8 reservoir logging standard delve, hoping to provide some reference for Chang 8reservoir optimization.
