| 1. | High frequency lake - level change of 3rd member of shahejie formation and prediction of lowstand sand body in dongpu depression 东濮凹陷沙三段高频湖平面变化及低位砂体预测 |
| 2. | The climate controls different types of sequences by affecting the relations between rainfall and evaporation 气候通过降雨量和蒸发量的关系影响湖平面,进而控制层序类型。 |
| 3. | Compared c13 & o18 isotope analysis curve with lake level curve , further analyzed palaeoenvironment 通过分析、对比碳氧同位素曲线与湖平面升降曲线,对古沉积环境的变化规律有了进一步的认识。 |
| 4. | Experimental process shows that variance of underwater distributary channel and declining rate of lake plane are closely related to moving intension of motive soleplate 实验过程显示,水下分流河道的变迁与湖平面的下降速率及活动底板的运动强度密切相关。 |
| 5. | The formation and evolution of the sequence stratigraphy of the yanchang formation are governed by slow tectonic subsidence , warm humid climates , sediment supply and lake - level fluctuations 延长组层序地层的形成与演化主要受控于当时缓慢的构造沉降、温湿气候、陆源碎屑物源供给及湖平面升降等地质因素。 |
| 6. | That the black mudstone deposited in deep water interbedded with salt and gypsum deposited in shallow water shows that during the sedimentation of 3 ( superscript rd ) and 4 ( superscript th ) sub - member , the lake level changes frequently 也正是由于湖平面变化频繁,在沉积中心的周围主要物源方向上形成一系列低水位期的砂体。 |
| 7. | For tianjin olympic center stadium project , parameters determination of a natural lake used as cooling pond and the layout plan of the lake were introduced , including the flow scheme of recirculating cooling water system , calculation of heat released from cooling pond , engineering arrangement for the lake , and the lake water treatment , etc 摘要结合天津奥林匹克中心体育场工程,介绍了利用天然湖作为冷却池的参数确定及湖平面设计,具体包括冷却循环水系统流程、冷却池排热量计算、冷却湖的工程布置、湖水水质处理等。 |
| 8. | Depositional cycles on basin scale have been interpreted as the result of depositional response to tectonism such as episodic rifting , polyphasic compressive flexural subsidence and reversion , and differential subsidence of fault blocks ; while the formation of high frequency sequences was attributed to variation in lake level and sediment supply 盆地规模的沉积旋回多是盆地幕式裂陷、多幕挤压挠曲沉降、多期构造反转、断块差异沉降等构造作用的沉积回应;高频层序单元的发育则主要与湖平面和沉积物供给量的变化有关。 |
| 9. | On the basis of the feature of paleostructure , paleogeography and lake level fluctuation in chang - 6 to chang - 8 oil - bearing layers , this text researchs paleogeographic feature and evolution . chang - 8 stages are the early days of lake basin outspread , chang - 7 stages are steadies stage of lake basin outspread , chang - 6 stages are shrinkage of lake basin , the lake level slowly droping , lake strandline moving eastward 根据古构造、古地理、湖平面升降等特点研究了长_ 6 ?长_ 8期岩相地理特点及其演化,长_ 8期是湖盆扩大的初期;长_ 7期为湖盆扩大阶段中稳定期;长_ 6期为湖盆扩大阶段中开始萎缩,湖平面继续缓慢下降,湖岸线向东迁移。 |
| 10. | The integrated study of heavy mineral , palaeocurrent direction , and sedimentary facies distribution has disclosed that the detritus are derived chiefly from the southeast and east - northeast during the deposition of the yanchang formation in the late triassic . the variations in the palaeocurrent directions have consequences for the development and distribution of the sequence stratigraphy and sedimentary facies of the yanchang formation . the major and trace element analyses of the mudstones from the yanchang formation also show that the lake waters would be freshened to brackish 初次通过泥岩常、微量元素测试资料和沉积学分析得出,延长期富县探区湖泊水体属于淡水-微咸水,微量元素含量及其比值在剖面上的变化对延长期湖平面升降和气候的演变具有良好的响应,湖平面升降、气候演变对层序地层的发育有着直观而又重要的影响。 |
