摘要: 本文论述了塔里木盆地志留-第三系主要碎屑岩储层的岩石学特征、砂体成因类型及展布、成岩作用及成岩演化特征、储集空间的成因类型及储集性能,在此基础上指出塔北地区的苏维依组、上白垩统、下第三系、中-上三叠统及东河砂岩、塔中地区的东河砂岩以及塔西南地区的中新统、下白垩统为本区最好的储层,具备了大中型油气藏形成的储集条件;同时还指出本区三叠系、东河砂岩等储层埋藏深、储集物性好,是国内外极为少见的深埋优质储层,并分析了其形成条件.Abstract: This paper deals with the characteristics of petrology,genetic type and distribution of sand bodies,diagenesis and diagentic evolution,genetic type of porosity and reservoir property of Silurian-Tertiary clastic reservoirs in the Tarim Basin.It was considered that Suweiyi Formation (Miocene),Upper Cretaceous,Lower Tertiary,Upper to Middle Triassic and Donghe Sandstone (D3d) in Northern Tarim Basin,Donghe Sandstone in Central Tarim Basin,and Miocene,Lower Cretaceous in Southwestern Tarim Basin were the best reservoirs,and giant to middle oil and gas fields could be formed in those reservoirs.It was also pointed out that the deep buried reservoirs such as Triassic and Donghe sandstones with favorable reservoir property were rare in the world.Their formation conditions were analysed in detail.
