The reservoir quality is strongly influenced by the depositional facies and diagenesis of the Chang 2 sandstones of braided river facies in Qinghuabian oil field.
摘要青化砭油田上三叠统长2辫状河砂岩储集层物性主要受沉积相及成岩作用的控制。
The sedimentary facies mainly consists of 5 types, such as meandering river, braided river, braided river delta, lake and swamp lake.
沉积相类型主要为曲流河、辫状河、辫状三角洲、湖泊、沼泽化湖泊等5种。
There are three main types of sedimentary facies: braided-river delta, slip turbidite fan, near-bank submerged alluvial fan.
确定研究区沙三段主要发育有辫状三角洲、近岸水下扇、滑塌浊积扇等几种沉积相类型；
In vertical, from E31 to E32, it changes from braided river delta to a shallow lake facies, thus, formed a cycle which lithologic character is rough at bottom.
在纵向上，从E31 -E32，从下向上由辫状河三角洲相变为浅湖相，构成了一正旋回沉积。
