An inverse method was used to estimate the wind stress from the observational data of current and the solution of time-dependent Ek-man problem, in shallow, homogeneous water.The calculated results have shown that the magnitude of wind stress coincides with the results obtained from calculation using the quadratic drag law, with a mean drag coefficient of 1.20×10~(-3) for wind velocity greater than 6.8 m/s and less than 14m/s.

Numerical experiments are made for different bottom topographies in order to examine the effect of topography on tidal amphidromic System. Tidal charts are drawn from the obtained results and discussed. It is concluded that (1) for the shift of amphidromic points with respect to the central axes of rectangular waters, the effects of both friction and bottom topography are important. For shallow waters the shift is due mainly to friction; for waters of greater average depths and whose bottoms have slopes in the...

Numerical experiments are made for different bottom topographies in order to examine the effect of topography on tidal amphidromic System. Tidal charts are drawn from the obtained results and discussed. It is concluded that (1) for the shift of amphidromic points with respect to the central axes of rectangular waters, the effects of both friction and bottom topography are important. For shallow waters the shift is due mainly to friction; for waters of greater average depths and whose bottoms have slopes in the transverse direction, the effect of topography is a main factor in causing the amphidromic points shift. (2) Friction can cause the amphidromic poins to move to the left of the central axes only. topography. however. can make them move to the left or the right of the central axes, depending on the direction of the transverse slopes.

为了探讨海底地形对旋转潮波系统的影响,本文对不同底形情况下的潮波运动进行了数值试验。根据试验结果绘制了同潮图并作了讨论。其结论是:(1)对无潮点相对于矩形海域中轴线的偏移来说,摩擦的影响和海底地形的影响可能都是重要的。如果是浅水区域,这种偏移主要是由摩擦引起的,但对平均水深较深、海底在横方向上有坡度的水域来说,底形效应是导致无潮点偏移的主要因素;(2)海底摩擦仅能使无潮点偏移到中轴线的左方(如果人们面向湾顶),而底形则可能使无潮点偏移到中轴线的左方或者中轴线的右方,这将取决于海底横向倾斜的方向。

The first three formations belong to the Lower Triassic and the last one to the Middle Triassic.

The Qinglong Group can be divided into four formations, i.e. Yinkeng Formation, Helongshan Formation, Biandanshan Formation and Dongmaanshan Formation. The first three formations belong to the Lower Triassic and the last one to the Middle Triassic. According to“single factor analysis and comprehensive mapping method”, the petrography and lithofacies paleogeography of every formation of Qinglong Group has been studied. The paleogeographical features of Yinkeng Age and Helongshan Age in this region were characterized by shallow water elastic platform, shallow water carbonate platform, deep water slope and deep water basin, with water becoming deeper northwards. In Biandanshan Age, the deep water area gradually narrowed northwards but the shallow water sedimentary area was widened. Meanwhile, the shallow water banks were well developed. In Dongmaanshan Age, the whole Lower Yangtze Sea became a shallow water sedimentary area where gypsum lagoons, restricted sea, dolomite flats, dolo-micrite flats, banks, parabanks and embryonic banks were developed. The deep water basin and slope are beneficial to the preservation and transformation of organic materials. The isopach map of Lower Triassic dark coloured rooks has been drawn showing the distribution of possible source rocks of oil and gas. Oosparite and intrasparite which formed in shallow water banks, postpenecontemporaneous dolomites and structurally fractured limestone may be favorable for reserving oil and gas. Gypsum and anhydrite in Dongmaanshan Formation and dense micrite in all formations may serve as good cap rocks of oil and gas. From the combination of the formation, preservation and cap of oil and gas, it can be seen:(1)The formation, preservation and cap conditions are very good in Changzhuu, Liyang area in the eastern part and Tongling, Guichi, Anqing in the middle part where all the profitable conditions are concentrated;(2)In the western part, the good conditions of petroleum formation exist in the Yinkeng Formation, but the cap rocks are not good enough;(3)It can be inferred that in this region where the deep water deposits and the dark colour rocks are well developed, the primary traps such as Jurong type might be formed if there are structural fractures in rocks.

下扬子地区的青龙群地层分殷坑组、和龙山组、扁担山组和东马鞍山组。前三组属下三叠统,后者属中三叠统。根据“单因素分析综合作图法”,对青龙群各组进行了岩石学及岩相古地理学研究。殷坑期与和龙山期的古地理面貌以浅水碎屑岩台地、浅水碳酸盐岩台地、深水斜坡和深水盆地为特征,海水自南而北加深。在扁担山期,深水区域不断向北收缩,浅水区域向北扩展,浅滩发育。至东马鞍山期,整个下扬子海变为统一的浅水沉积区,膏泻湖、局限海、云坪、云灰坪、滩、准滩和雏滩发育。深水环境为有利的生油区。从青龙群的暗色岩层等厚图可以历史地和全面地看出有利生油岩的分布规律。浅滩环境形成的粒石灰岩、准同生后白云岩以及具构造裂缝的石灰岩,都可作为有利的油气储集岩。东马鞍山组的石膏和硬石膏层是良好的油气盖层,致密的灰泥石灰岩亦可作为油气盖层。综合本区的油气生、储、盖条件,可以看出:(1)东部的常州、漂阳地区及中部的铜陵、贵池,安庆地区,具有良好的生储盖组合。(2)西部殷坑组生储条件有利,盖层条件一般。(3)在深水环境的暗色岩层发育区,如果构造裂隙发育,则可望形成句容式的自生自储油气藏。
