The characteristics, reservoir quality and types of lacustrine braid deltas

摘要: 辫状(河)三角洲是湖泊三角洲的主要类型,它与扇三角洲和正常三角洲有着明显的区别。其发育背景广泛,沉积物分选较好,杂基含量少,孔渗性较好,砂体呈席状展布,面积较大,因而具有较好储集油气的潜力。笔者对辫状三角洲的沉积特征、储集性能进行了详细的描述,并对其分类进行了探讨。

Abstract: A braid delta is an important type of lacustrine deltas. Unlike fan deltas and normal deltas, the braid deltas are widely developed and characterized by well-sorted sediments, minor amount of matrix, relatively good porosity and permeability. The sandstone bodies always occur as sheets over a wide range of scales, and thus have significant reservoir potential. The sedimentary characteristic, reservoir quality and types of the braid deltas are discussed in detail in the present paper.
