The research results indicate that the qualities of the Jurassic reservoir are dominated by construction. Good reservoirs lie to an advantaged nose protrusion, nearly relating to the distribution of sedimentary micro-facies. The reservoir that lies on the main position in the riverway has better gathering characters. Because argillaceous content is increase and the porosity and permeability became smaller, the character of the reservoir becomes bad in the flood plain area that lies on the skirted riverway and between riverways. Characters of the layer relate to the distribution of main sand-body that the better feature of the layer and the bigger thick of sandbody layer.

通过综合储层含油性、非均质性、分类研究的GIS 分析结果，研究认为：长西油田侏罗系储层性质受构造控制，储集性好的储层在区域上大多属于一个有利的鼻状隆起；且与沉积微相的展布密切相关，在河道主体部位的储层其储集性一般都较好，而在河道侧缘和河道之间的泛滥平原沉积区，泥质含量增加，孔渗性变差，储层的储集性也变差；储层优劣与主砂带的分布也有关，砂层厚度越大，储集性越好。

Comprehensive investigation of the quantity, quality and utilization of the riverbank was made using remote sensing, geography information system, and geoinformation tupu techniques based on setting a series of databases of the migration of the river bank from 1950', the water channel changes, the riverbank revetments, and the riverbank utilization of the Yangtze river in Jiangsu province.

Investigate the assisting of the relation and soil and groundwater monitoring data among the surface feature and image established the relation of the spectrum characteristic with surface feature ,using two kinds of classification and improved post-classification, methods lies two respects: 1Salt steep spectrum luminance value curve of ground higher than surface feature average luminance value curve obviously, and other surface feature luminance value lower than or have around average luminance value curve little wave water body mean the land water areas among them obviously, including the river and surface of water , surface of water of the reservoir and hole pool surface of water By view trend of the

从计算结果得出，盐渍地上的NDVI 值分布在一定范围内，这样就可以取一定的阀值，将反射率较低的盐渍地提取出来。根据盐渍地分布与地下水的相互关系，对分类后的图像进行处理，提高了精度。2 充分利用遥感与GIS 技术在地学分析中的优势，计算各类盐渍地面积、荒漠、水体面积变化，分析近三十年来研究区土地盐渍化动态变化的规律，包括面积变化、盐渍化程度的变化，分析大范围时间尺度上土地盐渍化动态发展的整体趋势。
