By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1～N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.

进一步研究了本区碎屑岩储层的岩石学特征、成岩作用特征、物性特征，研究认为该区储集体类型有分流河道砂体、分支河道砂体、河口坝、远砂坝、席状砂砂体、滨湖砂滩、浅湖砂坝砂体及灰坪；N1层属于低孔、特低渗储层，孔隙类型以原生、次生粒间溶孔为主；分析了影响储层物性的因素主要为沉积作用、胶结作用、溶蚀作用和构造破裂作用；进行了储层评价与有利相带预测，将储层分为三类并划分了有利区带、较有利区带，认为Ⅶ号断层以东的辫状河三角洲前缘亚相和部分浅湖亚相是N1的有利储集相带，储层以Ⅰ、Ⅱ类为主。

It was found that halite was closely cemented with soil particles, thenardite (Na_2SO_4) was transformed from mirabilite (NasSO_4·VlOH_2O) by dehydration, and the glanberite [Na_2Ca (SO_4)_2] was formed by calcium sulfate and sodium sulfate. These salt crystals separated were clear, without any mixture.

Some spore-pollen assemblages of late Trias and the youngest zircon of 225Ma were also obtained in this type.Deriveration of the ore is from the upper crust according to the features of trace elements,zircorn U-Pb age and initial value of ~(87)Sr/~(86)Sr.It has not any charateristics of the mantle.

底辟-侵位角砾岩是本次工作新发现的，它在空间上与构造-膏溶角砾岩密切伴生，剖面上呈脉状或火焰状分布，局部呈脉状穿刺于围岩中，其胶结物中含有晚三叠世的孢粉组合，最年青锆石的年龄为225Ma，角砾岩本身是铅和锌的富矿体。
