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。

This paper reviewed the developments in 2-D numerical model of the water flow. By means of the latest observation data of the prototype, the detailed analysis was made on the major thalweg, section, island and bottomland, the erosion and deposition of the river bed and the scour hole near the dock and the law of the fluvial process was obtained. Based on the related references, the evolution trend of the channel after the Three Gorges was finished was predicted. The 2-D mathematical model of the water flow was set up and validated using the latest data. With the model, the flow and velocity of several cases were calculated. The stability computation of the bank at the typical section under difference conditions was carried out by adopting the world widely used Geo-Slope slope stability analysis program. Finally, the synthetical evaluation on the influence of the project on the flood level, velocity, river circumstances, bank protection and flood prevention was made and the conclusion that the construction of the dock had little effect on the flood discharge was obtained.

The paleochannel-Ⅱ might form during the Holocene Optimal period.
古河道-Ⅴ形成于风沙-Ⅱ和Ⅲ期形成之前,可能是末次冰期之前,即中更新世或更早,这时河流能够进入古松辽大湖;古河道-Ⅳ形成于风沙-Ⅱ和Ⅲ期形成之时,可能是末次冰期时期,这时河流与松辽大湖萎缩,规模减小,河流已不能进入松辽大湖,而是消失在沙地之中;古河道-Ⅲ形成于风沙-Ⅱ和Ⅲ期形成之后,可能是末次冰期末期的冰消期,这时气温升高,大量的冰雪融水进入河流,促使河水漫流,流入沙垅垅间洼地,开始造成古西拉木伦河、古老哈河与教来河水文网之间的相互联系;古河道-Ⅱ形成于全新世适宜期时期,统一的西辽河形成,伴随气候变化,出现多次风沙进退,对应于风沙-Ⅰ期;河道-Ⅰ是现在,同属于风沙-Ⅰ期,活动沙地集中在翁牛特等地。
