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。
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.
