depositional sequence meaning in English
沉积层序
沉积序列
Examples
- The depositional sequences of braided rivers mainly consist of braided channel lag deposits and mid - channel bar sandstones
辫状河沈积主要发育河道和心滩微相，泛滥平原微相不太发育。 - The depositional sequences of meandering river are typical of the development of point bars , crevasse - splays , natural levees and flood plains
曲流河沈积以发育点砂? 、决口扇、天然堤和泛滥平原等微相单元?特徵。 - According to the abundance well logging , mud logging and core analysis data , gaotaizi reservoir has been classified into four sand group with the principle of cycle comparison and classified control . based on the detailed study of lithologic character , sedimentary structure , paleontologic fossils , depositional sequence , rock association and logging data , the microfacies of the studied area are divided into such seven types : subaqueous distributary channel microfacies ; river mouth bar microfacies ; subaqueous interdistributary channel microfacies ; subaqueous crevasse channel microfacies ; subaqueous natural barrier microfacies ; distal bar microfacies ; delta front sheet sand microfacies . the characteristic of each sedimentary microfacies are described detailedly
通过研究大量测井、录井资料和岩芯资料，依据“旋回对比，分级控制”的原则，把研究区高台子油层划分为g 、 g 、 g 、 g四个砂层组。通过对研究区岩性、沉积构造、古生物、沉积序列、岩石组合及测井曲线特征进行研究的基础上，认为研究区高台子油层属于三角洲前缘亚相沉积，并将研究区沉积微相划分为：水下分流河道、河口坝、水下分流河道间、水下决口扇、水下天然堤、远砂坝、席状砂等七种微相类型。
