upper palaeozoic meaning in Chinese
上古生界
Examples
- The target strata in yulin gas field lie in the bottom of shanxi formation of permian , upper palaeozoic
摘要榆林气田目的层系位于上古生界二叠系山西组底部。 - The main conclusion of research is that the formation of shihezi and shanxi in the upper palaeozoic gas pool at the sulige gas field is characteristic of low permeability and medium porosity
研究的主要结论：苏里格气田上古气藏下石盒子组-山西组的储层为低渗透率、低孔隙度储层，沉积相类型主要是河流沉积。 - Due to distribution of sand body and very variety of reservoir physical characteristics and serious nonuniformity in the upper palaeozoic gas pool at the sulige gas field , during the course of gas and oil field development , it is urgent problem about how to predict precisionly the distribution of high permeable and thick reservoir bed , precisely choose the place of productive well
苏里格气田上古气藏的砂体分布、储层物性变化很大，非均质性严重，因此，在开发过程中如何准确预测高渗厚储层的分布、准确选定开发井位，是高效开发苏里格气田急待解决的问题。 - The sedimentary formation can be summarized as rift bay filling sequence , epicontinental sea filling sequence , offshore debris lake basin sequence and inner continental lake basin sequence . a framework of sequence stratigraphy for the upper palaeozic strata is established in the area . the helan aulacogen of upper carboniferous in the west margin of ordos can be divided into 12 sequences , and most of the upper palaeozoic strata in the area can be divided into 15 sequences
本文对研究区内上古生界进行了层序地层学探讨，将本区沉积建造概括为裂陷海湾充填层序、陆表海充填层序、近岸碎屑湖盆层序和内陆湖盆层序，建立了研究区上古生界层序地层学格架，西缘贺兰拗拉槽上石炭统划分为12个层序，本区大部分地区上古生界可划分出15个层序，并全面地概括了层序演化各阶段的具体特征。 - On the basis of the analyses of peripheral ancient land , types of sand stone , light and heavy mineral associations and directions of palaeoflow , it is considered that detrital material of terrigenous origin of the upper palaeozoic in this area come from south provenance and north provenance , respectively , yinshan ancient land in the northern and east qinling ancient land in the southeastern
根据盆地周缘古陆、砂岩类型、轻、重矿物组合及古水流方向等特征的分析，认为研究区上古生界陆源碎屑物质来自南、北两大物源区，即北部的阴山古陆和东南部的东秦岭古陆。
