And after analyzing the heterogeneity of sand body, point the minor channels, especially, have important influence on the intraformational oil-flooding direction, forming and distribution of remaining oil because of their function as barrier, breaking fluid and poor permeability in fluvial sand body.

通过非均质性研究，进一步揭示了单一河道砂体内部非均质性，特别是次分流河道砂体的分布，在河道砂体内起到遮挡、阻流、特低渗透等作用，对层内水驱油方向、剩余油形成与分布具有重要影响。

The medium-grained sandstones and medium-fine-grained sandstones form good reservoirs and the poststones medium reservoirs, while siltstones form poor reservoirs and pelitic siltstones poorest reservoirs. Sand bodies mostly develop in sand-flats, tidal channels and distributary channels of braided stream delta microfacies. The reservoir rocks of sand-flat and tidal channel are best with the physical property. Diagenesis such as compaction, cementation and dissolution has strongly reformed the reservoir rocks and the late dissolution has greatly improved their porosity and permeability.

中粒砂岩、中细粒砂岩属好储层，细粒砂岩属中等储层，粉细砂岩，粉砂岩属较差储层，而泥质粉砂岩则属差储层；砂坪、潮道和辫状河三角洲分流河道微相中的砂体最发育，它们决定了储集岩的发育、分布及原始物性条件；砂坪和潮道储集岩的物性最好，辫状河三角洲分流河道储集岩的物性次之，砂泥混合坪、辫状河三角洲分流河道间储集岩的物性较差；成岩作用对本区CⅠ油组的储层有强烈的改造作用，尤其是较晚期的溶蚀作用对岩石的储集性能有明显的改善，对本区CⅠ油组中孔高渗透储层的形成有很大的贡献。

Aimed at the complexity of fluvial strata, such measures as well cyclical comparison, step control and geological analysis of reference beds have been applied. Moreover the paper has developed a set of methods the techniques to extract the parameters controlling the formation of intra-sandbody thin interbeds. The present study has examined how thin interbeds affect the frame property and heterogeneity of individual sandbodies; revealed the permeability space distribution mode of meandering distributary channel's single side lithosomic body and straight distributary channel's aggrading lithosomic body. Through applying the distributary channel sandbody structural unit classifying and identifying method achievement, some horizontal wells have been deployed to dig the residual oil in the top of hick pay zone in the xing8-9 area, which shows better effect after they have been put into production.

针对分流河流砂体沉积特点采用了旋回对比、分级控制、不同相带区别对待的单油层对比方法；利用取心井、对子井等资料研究形成了分流河道砂体内部结构单元的倾角、倾向、规模等参数的提取方法；搞清了内部结构单元对单一砂体内非均质性的控制作用，建立了分流平原相单一点坝侧积体及顺直型分流河道单一加积体层内渗透率分布模式及剩余油分布模式，应用分流河道砂体结构单元划分方法识别研究成果，在杏树岗油田杏八九区纯油区部署了水平井，投产后见到了较好的厚油层顶部剩余油挖潜效果。

The effects of wetting bed and drying bed are discussed simultaneously.

首次针对180°强弯曲河道、90°双支以及45°三支分叉渠道，数值预报了溃坝波的演进过程，揭示了溃坝波在弯曲河道中内外两岸速度与水位变化，在分叉河道中自动进行流量与动量再分配，在叉点角区形成旋涡、壅高等复杂运动特征，同时反映了湿底与干底的影响。

Using maximum flooding surface and local explosure erosion surface as the correlation framework surface in the 4-th hierarchical base-level cycles, sand-body in the 3-th hierarchical base-level cycles formed in the 4-th hierarchical base-level cycles may be correlated layer by layer. The law of the sand-body and the characters of reservoir heterogeneity formed in the 4-th hierarchical base-level cycles are discussed. The study shows:①During early period of the 4-th hierarchical base-level cycle rising, subaqueous distributary channel formed, continuously stacked vertically, and migrated in limit range laterally, and channel sand-body stretches farther longitudinally, and lacks interbeds of mud rock and siltsand in sand rock, reservoir heterogeneity is relatively weak.②During mid-period of the 4-th hierarchical base-level cycle rising, subsaqueous distributary channel migrated actively, channel divided and converged strongly to form netted sand-body and sand sheet mainly, but interbeds of mud rock and siltsand increases gradually in sand-body, reservoir heterogeneity increased.③During later period of the 4-th hierarchical base-level rising and early period of the 4-th hierarchical base-level falling, reservoir sand-body was poor, and only form thin sand-body of subsaqueous distributary channel, subsaqeuous creveas and distal mouth bar, sand-bodys are surrounded by mud and silt rock.

General layout: General idea should focus on protecting urban water sources, restoring riverways, wetlands and groundwater, improving the water body function, strengthening water resources allocation and water function regions management. Based on existing water project structures, the generallayout follows as that urban water sources conservation on the upriver, wetland and groundwater restoration on mid-river and coastal wetland and estuarine eco-area restoration on the downriver, achieve the target that rivers and lakes 'connection, green bank, clean water, flowing river', then form aquaticecosystem protection and guarantee system.

During the paleo-geography evolution, inland lacustrine basin began to form, and the two delta skirt in east and west lakeshore are primary formed in Chang 10, lacustrine basin subsidized quickly, lake district enlarged rapidly and destructive delta are developed in Chang 9, delta are more developed in Chang 8, lakeshore line move outward at large range, turbidite developed well near west lakeshore, delta range is decreased in east lakeshore in Chang 7, features of lacustrine basin are changed remarkably, deep lake and half deep lake area is decreased greatly, while delta sedimentary system is developed at its most in Chang 6, framewok is inherited better, but delta′s construction is slowed and is swamping at large scale in Chang 4+5, lacustrine basin began to be silting, shrinking and dying out, and riverway gradually developed well since Chang 3, distributary riverway developed best in Chang 2, because of imbalance subsidence, subsidence center is formed in east Zichang area and in which lacustrine turbidite is sedimented.

在古地理演化过程中，长10期内陆湖盆开始形成，东西两岸两大三角洲裙初步形成；长9期湖盆快速下沉，湖区迅速扩大，三角洲多为破坏性的；长8期三角洲进一步发育；长7期湖岸线大幅度向外推移，西部浊积岩发育，东部三角洲面积明显减小；长6期湖盆面貌发生了显著的变化，深湖－半深湖面积大大减少，三角洲沉积体系极为发育；长4+5期继承了长6的沉积格局，三角洲建设进程减慢，三角洲大面积沼泽化；从长3期湖盆开始逐步淤浅、萎缩、消亡，河道逐渐发育；长2期分流河道发育；长1期由于差异沉降，在东部子长一带形成沉降中心，沉积了湖相浊积岩。

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。

Geomorphology：地形学

多年以前担任地形学(Geomorphology)课程,初识秀姑峦溪地形发育的始末;秀姑峦溪瑞穗以上的河段原为花莲溪的上游,缘由秀姑峦溪坡度大、向源头不断侵蚀,穿越海岸山脉接上花莲溪的河道,河川袭夺形成现今的秀姑峦溪,原花莲溪上游被夺流量骤减 ,

Hydrology：水文学

水文学(Hydrology)是研究地球上各种水体的形成、时空运动及其变化规律和地理分布的科学[4],其最基本的内容是地球上的水分循环及水量平衡. 森林作为流域生态系统中一个重要的组成部分,各流域的降水都会受到森林的影响后再流入河道,

overland flow：地表径流

如果是蓄满状态,则多余的一部分水量将形成地表径流(Overland flow)流入河道,另一部以渗透的方式流入植被根区蓄水层及地下水蓄水层. - 当根区含水率(LLmax)达到壤中流临界值(TIF)时,则产生壤中流(Interflow). - 基流(Baseflow)产生于地下水蓄水层,

flash flood：暴洪

主要是暴洪(Flash flood)的侵蚀,其次则是风蚀. 该地在季风季节里常出现暴洪流入峡谷中,由于突然暴增的雨量,造成暴洪的流速相当快,加上狭窄通道将河道缩小,因此垂直侵蚀力也相对变大,形成了羚羊峡谷底部的走廊,以及谷壁上坚硬光滑、如同流水般的边缘.
