沉积韵律 meaning in Chinese
sedimentary rhythm
Examples
- Thus it became well - known for frequent geologic - disaster and landslide in the stratum area . xigeda soft rock is made up from minute sandstone , mud siltstone , siltstone mud and mudstone . it is inland fluviolacustrine phase deposit rock with rhythm - cyclic character of depositional geology
昔格达组极软岩属内陆静水河湖相沉积，主要由粉细砂岩、泥质粉砂岩、粉砂质泥岩和泥岩组成，具有明显的沉积韵律特征。 - The fluvial , delta , and lacustrine sedimentary system was realized according to the analysis of the fossils , sedimentary structure , sedimentary cycle , rhythmic bedding and other criteria in the yanchang formation . the sedimentary microfacies of the chang - 6 oil - bearing beds was identified through its fine description , and the evolution of palaeogeography was revealed
通过古生物、沉积结构与构造、沉积韵律、沉积厚度与沉积旋回特征和测井相分析等，在延长组中识别出河流、三角洲、湖泊沉积体系，以及长6油层组的沉积微相，并对长6油层组各小层的沉积微相进行了精细描述，反演出其古地理的演化历程。 - And sedimentary microfacies of the main reservoir sands has been divided according to regional background , lithology or rock texture , sedimentary structure , sedimentary rhythm , grain size analysis , palaeontological assemblage , log and seismic facies . with all the heterogeneity appraisal parameters , the macro - heterogeneity of reservoirs has been evaluated quantitatively
从区域背景、岩性及岩石结构、沉积构造、沉积韵律、粒度分析、古生物组合、测井相和地震相分析入手，确定了埕岛油田馆上段储层为陆相沉积河流亚相，并进一步划分了馆上段储层主力油砂体的沉积微相。 - From sedimentology symbol such as rock assembled , sediment gradus , sandstone grading analysis , protogene sedimentary structure , ichnofossile and logging facies etc and palaeoenvironment background , it is confirmed that shen84 - an12block s34 segment is braid river delta system , not fan delta system ( abrupt slope ) . then it can be more partition as braid river delta plain sedimentary assembled , delta front sedimentary assembled and prodelta sedimentary assembled on core and log assembled . and delta plain sedimentary assembled can be identified four microfacies : braided distributary channel , crevasse splay , overbank deposits and interdistributary bay
沉积微相研究是储层非均质性研究的基础，研究区有丰富的岩芯资料和测井资料，通过岩石组合、沉积韵律，砂岩粒度分析、沉积构造、古生物遗迹和测井相等沉积学标志，结合古环境背景，确定沈84 ?安12块s _ 3 ~ 4段为辫状河三角洲体系，而不是前人所认为的扇三角洲(陡坡型)体系，在岩芯和测井组合上可进一步划分为辫状河三角洲平原沉积组合、三角洲前缘沉积组合和前三角洲沉积组合，其中三角洲平原沉积组合又可识别出辫状分流河道、决口扇、分流河道边部和分流间湾四种微相类型；三角洲前缘沉积组合识别出水下分流河道、水下分流河道边部和分流河口坝三种微相。
