Examples
- The research shows that beir depression characterized as several resources , thin facies , and more kinds of reservoir . the lowstand system tract of nantun formation is the principal target reservoir with best source rock and reservoir . the upper mudstone developed in transgressive system tract of damoguaihe formation is the important regional sealing bed , forming the best oil source bed , reservoir , caprock pattern
综合研究表明，贝尔凹陷具有多物源、相带窄、储集类型多的特点，南屯组低水位体系域具备生油和储集条件，是海拉尔盆地的主要勘探目的层段，其上部的大磨拐河组水进体系域发育的泥岩是良好的区域性盖层，可以构成良好的生储盖配置。 - 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。
