Based on Coherens model, a 3 dimensional hydrodynamical and water quality mathematical model is established in finite difference algorithm.

中文摘要：本文在Coherens模型的基础上，建立了基于σ坐标的河口水域水动力和水质三维有限差分计算模式。

Results indicate that the total area of Kandelia in Tanshui estuary in years 1978, 1986, 1994 and 1998 is 47.62, 47.15, 81.43 and 103.80 ha, respectively.

So two widely separated colonies were established in 1607: one at Sagadahoc, near the mouth of the Kennebec River, in Maine; the other in modern Virginia.

于是两个相距甚远的殖民地于1607年建立起来了：一个在靠近缅因州肯纳贝克河口的Sagadahoc，另一个位于今天的弗吉尼亚州。

文蛤在我国南北沿海均有分布，并以受淡水影响的内湾及河口近海，如辽宁辽河口海区、山东莱州湾海区、江苏吕泗海区、广西北海湾海区及台湾西海岸等一带资源最为丰富。

Base on core observation and grain size analysis, and under associated consideration of logging trace characteristics, Chang8 reservoir in study area is classified into three sedimentatal microfacies, subsea river, mouth bar and river flank.3.The mian diagenesis in study area are: mechanical compaction, cementation, metasomasis and denudation in late diagenetic phase.4. In allocation of reservoir macroscopic heterogeneity, more heterogeneticer reservoir, class 1 and class 2, mainly locate in the center of subsea river or crook and divaricate of the river; class 3 and class 4 mainly locate in river flank, and the physical property of these locality are better.5. Diagenesis of reservoir have influence on the pore structure which influences the reservoir microscopic heterogeneity. The better the pore structure is, the slighter the reservoir microscopic heterogeneity is; on the contrary, the reservoir microscopic heterogeneity is serious.

本次研究所取得的主要成果及熟悉有：1、将合水地区长8储层细分为6个小层：长8_1~1、长8_1~2、长8_1~3、长8_2~1、长8_2~2和长8_2~3.2、依据岩心观察和粒度分析，并结合测井曲线特征，研究区长8储层分为水下分流河道、河口坝和河道侧翼四种沉积微相。3、研究区主要经历的成岩作用有：机械压实和压溶作用、胶结作用、交代作用、晚成岩期溶解作用。4、从宏观非均质性平面展布特征来看研究区宏观非均质较强的1类和2类区主要分布于水下分流河道中间或河道拐弯和分又处。3类和4类往则主要分布于水下分流河道侧翼，这些地方储层均质性相对较好。5、储层成岩作用影响储层的孔隙结构，储层的孔隙结构又对储层的微观非均质性有不同程度的影响，孔隙结构越好，则储层的均质性越好，储层的孔隙结构差，则非均质性强。
