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。

Any way i am more interesting of standing how to distribute our body weight . and of thinking where is your body weight or the which leg do place your body weight , and which part of your body you transfer your body weight , and which part of your body you can be stand , and how you can start to move and how you can transfer . of cause it ' s very important for keeping perfect balance . to be bale to keep beautiful gradus . and different speed 不管如何，我对如何分配我的身体重量更有兴趣,了解身体重心在哪里,或身体重心放在哪一支腿,把身体重量移动到身体哪一部位,要站在身体哪一部位,要如何开始移动如何转换重心,当然非常重要的是要保持完全平衡,能够保持优美的韵律,及产生不同的速度。
