target stratum meaning in English
目的层
Examples
- The target strata in yulin gas field lie in the bottom of shanxi formation of permian , upper palaeozoic
摘要榆林气田目的层系位于上古生界二叠系山西组底部。 - The chengbei fault terraces are host to many target strata , where the oil and gas pools tend to be vertically stacked and laterally connected , and thus have great potential for oil and gas exploration
摘要埕北断坡区具有优越的成藏地质背景，具有含油目的层多，油气藏类型多样，纵向叠置、平面连片的特点，油气勘探潜力巨大。 - The major modules : target stratum extract , transform processing , parameter extract , graphical display , prediction analysis and text editing . the whole systematic function is relatively overall and adaptability is relatively strong
该系统分为目的层提取、变换处理、参数提取、图形显示、预测分析、文本编辑6大模块， 26个子模块，整体系统功能较全面，适应性较强。 - 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。 - On the basis of composite exploration methods with gravity prospecting electric survey and setsmic prospectlog in mount liupanshan basin , a geophysical joint inversion method is applied to research and solve the problems about the contact relation between the basin and the mountain , distribution of faults and deep target strata , favorable structural trap features , and so on , which will provide a scientific basis for arrangements of oil and gas exploration
摘要在六盘山盆地进行重力、电法和地震综合勘探的基础上，应用地球物理联合反演方法研究和解决盆山接触关系、断层分布、深部目的层分布和有利构造圈闭特征等问题，为油气勘探部署提供科学依据。
