It was the first time the sequence stratigraphy study had been done all across Naimanqi Depression. Jiufotang Formation of Naimanqi Depression was divided into two third-class sequences (SQ1 and SQ2) and five system tracts (SQ1 has LST, TST and HST; SQ2 has TST and HST), and in High System Tract of SQ2, two fourth-class sequences were defined (Ssq1 and Ssq2).2. According to the analysis of core and logging data, we considered that it is the delta fan facies and established the electrofacies model.3. The distribution of reservoir sand bodies had been predicted in the areas without well data by combining the methods of sequence stratigraphy and reservoir inversion. In addition, we summarized the method and process of combining geology and geophysics to predict reservoirs and we made a good prediction by applying it.4. Combining with sequence and depositional types, sandstone thicknesses and reservoir properties, based on Petrel Software platform, we used fuzzy mathematics to comprehensively evaluate reservoirs and define favorable areas. We classified the reservoirs in Naimanqi Depression into five types (TypeⅠ, TypeⅡ, TypeⅢ, TypeⅣand TypeⅤ) and pointed out four favorable areas: Block Nai 1, Block of western Naican 1-Zhangjia Depression, Block Nai 6 and Block of Xinfa-Zhangjia Depression.
其主要创新点如下：1、首次在整个奈曼旗凹陷范围内进行了层序地层学的研究，将奈曼旗凹陷九佛堂组地层分为2个三级层序(SQ1和SQ2)和5个体系域(SQ1由LST、TST和HST组成，SQ2由TST和HST组成)，并在SQ2的高位体系域中又识别出两个四级层序(Ssq1和Ssq2)。2、根据岩芯分析和测井资料识别，定义了研究区扇三角洲沉积相类型，并建立了测井相模板。3、通过层序地层学的研究，结合储层反演，对奈曼旗凹陷层序格架内没有井的区域进行了储层砂体的空间展布预测，并总结了地质-地球物理综合储层预测的方法与思路流程，在应用中取得了良好的预测效果。4、结合层序、沉积类型、砂岩厚度和储层物性等方面，以Petrel软件为基础平台，利用模糊数学的方法进行储层综合评价及有利区划分，将奈曼旗凹陷储层划分为五个级别(Ⅰ类、Ⅱ类、Ⅲ类、Ⅳ类和Ⅴ类)，并预测了四个有利区块，分别为：奈1区块、奈参1西-张家洼子区块、奈6区块和新发-张家洼子区块

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.
