摘　　要： 通过对鄂尔多斯盆地子长油田长6油层组的岩石孔隙结构、孔渗关系、储层的空间分布研究,认为长6油层组在层内、层间和平面上,都存在较强的非均质性。主力油层长62主要发育在三角洲前缘的水下分流河道砂体中,非均质性较弱,油气相对富集,应是勘探开发的重点。 By the research on the pore texture of rock, the relationship between porosity and permeability and the space distribution of reservoir in Chang 6 reservoir group of Zichang oilfield in Ordos Basin, it is considered that much higher heterogeneity exists at the innerbed, the interbed and the plane. The main layer, Chang 62, is mainly developed at the sandstones in underwater distributary channel of delta front. This layer, which is characterized by poor heterogeneity and belongs to a hydrocarbon-rich area, is an emphasis in exploration and development.
