查询词典 sand flat

The medium-grained sandstones and medium-fine-grained sandstones form good reservoirs and the poststones medium reservoirs, while siltstones form poor reservoirs and pelitic siltstones poorest reservoirs. Sand bodies mostly develop in sand-flats, tidal channels and distributary channels of braided stream delta microfacies. The reservoir rocks of sand-flat and tidal channel are best with the physical property. Diagenesis such as compaction, cementation and dissolution has strongly reformed the reservoir rocks and the late dissolution has greatly improved their porosity and permeability.

中粒砂岩、中细粒砂岩属好储层，细粒砂岩属中等储层，粉细砂岩，粉砂岩属较差储层，而泥质粉砂岩则属差储层；砂坪、潮道和辫状河三角洲分流河道微相中的砂体最发育，它们决定了储集岩的发育、分布及原始物性条件；砂坪和潮道储集岩的物性最好，辫状河三角洲分流河道储集岩的物性次之，砂泥混合坪、辫状河三角洲分流河道间储集岩的物性较差；成岩作用对本区CⅠ油组的储层有强烈的改造作用，尤其是较晚期的溶蚀作用对岩石的储集性能有明显的改善，对本区CⅠ油组中孔高渗透储层的形成有很大的贡献。
