| 摘 要： | 准噶尔盆地西北缘斜坡区发育地层不整合油气藏。研究表明 ,二叠系内部各组地层之间呈不整合接触 ,在不整合面附近地层的孔隙度和渗透率明显增大 ,因而是油气运移的主要通道。玛北油田百口泉、乌尔禾组油藏原油物性差异与油气运移通道有关 ,百口泉组油藏是通过不整合面运移聚集的 ,油气性质以富含轻质组分和低密度为特征。不整合圈闭发育的扇体是油气聚集的场所 ,油气富集是在不整合面附近

| Abstract: | There are many unconformity reservoirs in the north\|western slope of Junggar basin. Near the unconformity surface, the porosity and permeability of rock has obviously been improved. The unconformity surfaces in Permian are the main paths of oil and gas migration. Oil and gas are accumulated near the unconformity surface. Baikouquan pools in Mabei reservoir where oil/gas migrating through unconformity surface are characterized by light components and light density. |
