侏罗系的 meaning in English
jurassic
Examples
- The reservoir is sand of silurian and jurassic especially of delta and distributary fluvial facies sand . the growth of well reservoir sand is the key fector for gas reservoir to form in this area . by the small porosity of silurian compact sand , the position where comparative homogeneous sand growth with little mud or fracture concentrated is the location for gas to enrich
该区储层为中上奥陶统、志留系、侏罗系和白垩系砂岩，但以侏罗系的三角洲和扇三角洲相水下分流河道砂体、滨湖相滩坝砂体和志留系滨岸砂岩为主要目的层。 - Abstract : through statistical analysis of the rock mechanic properties of upper jurassic and cretaceous red mudstones , siltstones and sandstones in the middle sichuan red basin , the range of their compressive strength , the features of the shearing strength and of the deformation curves are proposed in this paper
文摘:对川中白垩系、侏罗系的泥岩、砂岩、泥质粉砂岩的抗压强度进行统计分析，得出红层岩石作为地基时抗压强度的范围值供设计参考，对泥岩、砂岩的其他力学性质进行了评价。 - The results are shown as the followings : on the basis of studies of depositional environment of source rock and its petroleum potential assessment , the biomarker compositions of the five source beds ( hq , j2k , jiy , tjt , tsh ) in kuche basin are analyzed in detail and the effects of depositional environment and maturity on the biomarker compositions are also discussed . the results show that there is not clear correlation between the distribution of biomarker composition and the ages of triassic and jurassic . it is proposed for the first time in the kuche basin that the changes of biomarker composition in the coal can be classified into three stages with the maturity , and the regular changes of different biomarker parameters in the coal are revealed
以烃源岩沉积环境为背景，详细剖析了库车前陆盆地五套烃源层( j _ 2q 、 j _ 2k 、 j _ 1y 、 t _ 3t 、 t _ 3h )中煤、炭质泥岩、湖相泥岩、煤系泥岩的生物标志物组成特征，分析了沉积环境、成熟度对生物标志物组成的影响，指出同一烃源层在盆地不同地区生物标志物组成的差异，并认为生物标志物组成特征与三叠系和侏罗系的时代对应关系不明显。
