| 摘 要： | 延长组长6油层是鄂尔多斯盆地中生界最主要的含油层段，探明石油地质储量和原油产量占70％以上。近几年来，随着勘探程度的不断提高，在油层评价方面不断有新的认识．并不断有新油田的发现，志丹油田义正区即是近几年新发现的延长组长6油田之一。通过对志丹油田义正区延长组长6储集层的岩石学特征、孔渗条件、孔隙结构特征、成岩作用与孔隙演化，以及储层展布特征分析，总结了影响储集条件的主要因素，并进行了储层分类评价；通过含油性分析，总结了延长组长6低阻油层形成条件，认为储层物性和孔隙结构是影响油层电阻的重要因索；探讨了影响油气成藏的主控因素和油藏特征，并对油井产能进行了分析，指出志丹油田义正区延长组长6具有良好的勘探开发前景。

| Abstract: | Yanchang Formation Chang-6 reservoir is uppermost oil layer of Mesozoic Erathem in Ordos basin, proving up oil-geology reserves and base oil yield occupy more 70 percent. Recently, along with prospect degree unceasing improving, have new cognition to oil layer appraising and unceasing find new oil area. Yizheng area of Zhidan oil field is among Yanchang Formation Chang-6 oil field which have been found in near years. In this paper, the author analyzed petrodistinction, porosity and permeability condition, porous structure characteristic, diagenesis, porous evolution and reservoir distribution character, analyzed influence factors of reservoir conditions, classified reservoir horizons, summarized forming condition of Yanchang Formation Chang-6 low resistor oil layer by analyzing oil-bearing characteristicistics, consider that reservoir physical quality and porous structure is main influence factors; the author question the main factors of oil pool forming and characteristic, and analyzed oil well's output ability, consider that Yanchang formation Chang-6 have favorable prospect exploitation foreground. |
