Based on the analysis of sedimentary facies in individual wells and the correlation of three cross sections of sedimentary facies , it is elaborated that sedimentary facies of jianglingjiang formation are vertically and laterally developed within qianwei area . by the method of single - factor analysis , it is pointed out facies distribution of four key formations after thorough study of four geologic factors that could embody sedimentary environment and facies , that is the thickness of formation , grainstone and dolostone , and lithofacies . with the above results , combining with reservoir and structural features , of which the emphasis is the reservoir characteristics of different rock and microfacies types , it is pointed out favorable reservoir zones , by the method of multi - factors superposition 采用单因素分析法，选取并研究地层厚度、颗粒岩厚度、白云岩厚度和区域岩相等四种能反映沉积环境和沉积相的地质因素，指出了四个重点层段的沉积相平面分布特征；根据沉积相的研究成果，结合储层特征和构造发育特征，着重讨论了不同岩石类型和微相类型的储集特征，采用多因素叠合法对犍为地区嘉陵江组有利储集相带进行了预测，指出了有利储集相带的分布。
On the base of description and analysis of main fractures time - space developmental characteristics , this paper further expound formation mechanism of these two suites of fractures and control action of structure trap , favorable sedimentary facies distribution , process of hydrocarbon migration and accumulation , degree of hydrocarbon preservation and mineral dressing 在对柴西南区主要断裂时空发育特征描述与分析基础上，进一步阐明了这2组断裂的形成机制和对柴西南区构造圈闭、有利沉积相带、油气运聚成藏过程及油气藏保存、富集等成藏要素的控制作用。
Besides , the sedimentary facies of upper ganchaigou and lower ganchaigou formation were also mapped in supersequences which are the main target strata for exploration . the high resolution sequence stratigraphic framework showed the genetic relationship between the distributions of sedimentary facies and their tectonic settings . the near - source sedimentary systems such as subaqueous alluvial fan and lake - floor fan are often deposed in rise - hemicycles in the steep slope background in the north , the coarse lithology of fan - delta prograded from north to south in fall - hemicycles , and the braided stream facies are formed in the rise - hemicycles in gentle slope background in the south , braided stream facies prograded from sorth to north in the fall - hemicycles , but the lacustrine facies and salt lake facies developed in the middle part of the area 详细的沉积相研究发现，红狮地区第三系发育有冲积扇、水下冲积扇、河流、三角洲、扇三角洲、湖泊和湖底扇7种主要沉积相类型，并对作为区内主要勘探目的层系的下干柴沟组和上干柴沟组进行了以超层序为单位的沉积相平面编图，以较高的时间分辨率揭示了区内沉积相带的平面展布及其在不同构造背景中的分布规律，比如在北部的凹陷陡坡背景下，上升半旋回低水位期通常发育有水下扇、湖底扇等陡岸近源特征的沉积体系，下降半旋回高水位期，扇三角洲相粗碎屑岩由北向南进积;在南部的凹陷缓坡背景下，上升半旋回主要发育辫状河流相，下降半旋回辫状河三角洲相由南向北进积;而中部红柳泉一狮子沟一带则为湖泊相沉积和盐类沉积。
