摘要
鄂尔多斯盆地甘谷驿油男东区长6油层为该区的主产层之一.本文在长6储层沉积特征研究的基础上,对储层岩石学、成岩作用、孔候结构及物性特征进行分析、研究,并作出综合评价,结果表明,长6储层为中一低孔、低渗型储层,其储层主要表现为ⅢA类较差储层,但长61储层相对较好,次为长62储层,长63总体较差,以差储层、非储层为主.
Oil-bearing Chang-6 bed is one of the major oil producing formation in the east of Ganguyi oilfield in the Ordos basin. Based on a study of the depositional features of Chang-6 reservoir bed, the authors analyze the characteristics of lithology, diagenism, pore throat texture and physical property and then make an evaluation of the reservoir. The result is that the physical property of Chang-6 reservoir is of medium-low porosity and low permeability and Chang-6 reservoir is mainly of the type of Ⅲ_A. In the vertical direction, the best physical property is Chang 6~1, the secondary is Chang 6~2, and the worst is Chang6~3.
