摘要

四川盆地须家河组蕴含丰富的天然气资源，是西南油田公司天然气勘探和储量增长的主力层系之一。天然气主要储集在大面积展布的须家河组二段、四段和六段共3段大型砂岩储集体中。利用野外露头勘察和井下资料解释，解剖了须家河组单砂体的内部结构和规模，描述了砂体发育特征，剖析了大型砂岩储集体的形成机理。研究发现须家河组砂体单体规模有限、总体数量众多，单砂体之间存在高频切割式、低频切割式、搭接式和孤立式4种叠置方式，纵向上叠置、横向上搭接、空间上叠合连片，形成了“集群式”大规模展布的砂岩储集体。砂岩储集体的这种分布样式决定了须家河组天然气资源总体呈现中低丰度、大范围展布的特征。

Abstract

The natural gas resource in Xujiahe Formation Sichuan Basin is huge,which has become one of the most important layers for the gas exploration and reserve incresement in the Southwest oil/gas company CNPC.The natural gas is mainly stored in large scaled sandstone reservoirs of members Xu2,Xu4,and Xu6.Based on outcrops and well data,the inner texture and scale of single sandbody in Xujiahe Formation is analyzed.Then the characteristic of sandbody is described,and the forming mechanism of the large scaled sandtone reservoirs is studied.It can be found that the single sandbody is small,but the quantity of the sandbodies is large.The single sandbody stacks with each other in the following four patterns: high frequency cutting,low frequency cutting,lapping,and isolated.The sandbodies stacked with each other vertically,and laped with each other laterally,forming the clustered large-scaled sandstone reservoirs.The distributing character of sandstone reservoir resulted in the distribution of natural gas resource in large area with low abundance.

Key words： Large scaled sandstone reservoir; Characteristics; Forming mechanism; Xujiahe Formation; Sichuan Basin
