prodelta meaning in English
前三角洲；三角洲前沉积
三角洲前缘
Examples
- And there are three parfacies - - delta plain , delta front and prodelta and eleven microfacies which are distributary channel , channel bar , marginal bank ( point bar ) and so on . the text also discuss the sedimentary characteristic and cross section structure of every microfacies
识别出三角洲平原、三角洲前缘和前三角洲3个亚相及分流河道河床、心滩、边滩等11个微相类型，并对各微相类型的沉积特征和剖面结构进行了讨论。 - Furthermore , eleven sedimentary subfacies are identified . respectively , the sedimentary subfacies are delta plain , delta front , prodelta , braided delta plain , braided delta front , braided prodelta , fan delta plain , fan delta front , fan prodelta , saucer lake and deep lake
并进一步识别出11种亚相，分别为：三角洲平原、三角洲前缘、前三角洲、辫状河三角洲平原、辫状河三角洲前缘、前辫状河三角洲、扇三角洲平原、扇三角洲前缘、前扇三角洲、浅湖和深湖。 - Using sedimentary facies analytical and formation inverse technique , the depositional characteristics and distribution of dujiatai formation of this area were described , disclosing that delta front facies and prodelta facies were mainly developed in dujiatai formation . material source are mainly from southern and northeast of the working area . sand types are mainly of delta front subwater distributaries channel sand body , river mouth bar and sheet sand body with large degree of planar variation
2 .采用沉积相分析及储层反演预测技术，对新齐14井区杜家台油层储层沉积特征及展布特征进行了详细描述，揭示出本区主要目的层杜家台油层属t -扇二角洲沉积，发育扇三角洲前缘亚相及前扇三角洲亚相，物源主要来自于工区南部及东北部，发育的砂体类型土要为扇三角洲前缘水下分流河道砂体、河口坝砂体及席状砂砂体。 - 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。 - Furthermore , sixteen sedimentary subfacies are identified . respectively , the sedimentary subfacies are delta plain , delta front , prodelta , braided delta plain , braided delta front , braided prodelta , coastal lake , saucer lake , tidal flat , barrier island , lagoon , carbonate continental shelf , muddy continental shelf , open platform , local platform and evaporate platform
并进一步识别出16种沉积亚相，分别为：三角洲平原、三角洲前缘、前三角洲、辫状河三角洲平原、辫状河三角洲前缘、前辫状河三角洲、滨湖、浅湖、潮坪、障壁岛、泻湖、碳酸盐陆棚、泥质陆棚、开阔台地、局限台地和蒸发台地。
