As the river flow is increasingly controlled, the silt load will be less important.

随着对河流的控制日趋完善，则泥沙荷载就不那么重要了。

The results from the research indicated that:(1) This paper further indicates the control significance of southern boundary fault displacement component, which downthrown side forms syncline or anticline, and points out that 4 anticlines in south are adjustment zone and are the entering lake position of ancient river.

本论文的主要认识和结论如下：(1)进一步认识南缘边界断层位移量对下降盘形成次凹或横向突起的控制意义，认出南缘的4个突起是调节带之所在，也是古河流入湖处。

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。

In the work area, the Jurassic system Shaximiao gas reservoir is dominated by distributaries channel sand, mouth bar sand of river-lake delta depositianal system and fracture. The lateral change of the reservoir is fast, distribution rule of the gas reservoir is complex in vertical and horizontal direction. The gas reservoir is dominated by lithology and tectonic action etc. It is a lithological gas reservoir base of structural setting.

工区侏罗系沙溪庙组气藏受河流－湖泊三角洲沉积体系下的分流河道、河口坝砂体及裂缝综合控制，储层横向变化大，气藏纵横向分布规律复杂，受岩性、构造多种因素综合控制，为构造背景上的岩性气藏。

Based on the water environment spatial data mining and visualization method, the paper presents these main characteristics and innovations:①Measurement of contamination fluxes:A scene-based research strategy is proposed:measurement /water quality analysis→flow field simulation→contamination transformation rule→fluxes scene simulation→temporal-spatial rule analysis.②Serial numerical models of water environment in the Qiantang River:The controlled equations of the flow field model of the main river,united controlled equations of the main contamination fluxes and water quality prediction model at emergent time are set up.③GIS-based water quality and contamination fluxes decision-making assistance system:A water environment database has been set up;based on MapX and C#.net platform,a system has been developed to facilitate visual inquiry,decision-making and graphics export.
