The le - an oil field is located on the southern slope of dong - ying sag . there are two sets of ek basalt in its western block . depending on the drilling , the logging and the seismic date , tha ek basalt has the characteristics of high resistancs , the low sound wave defferance and faradic conductance , the smooth curve of self potential 乐安油田位于东营洼陷南斜坡上，其西区发育了两套孔店组玄武岩，根据钻井、测井、地震资料，孔店组玄武岩具有电阻率高、声波时差值和感应电导率值低、自然电位曲线平直的特点，地震波呈板状强反射；沉积期该区有有二次火山活动，玄武岩平面分布比较稳定，喷发方式为“裂隙式喷溢” ，火山口分别位于草12和草31井附近。
Aiming at reducing the roughness of the sidewalls in the manufacturing of the pmma liquid pool by co _ 2 lasers , in the hypothesis that the intensity of the laser has a guassian distribution , the temperature distribution in slab material with limited thickness is studied according to traditional thermal conductive formulas , and the condensing progress of the melted surface of sidewalls is researched . it is concluded from the discussion of temperature distribution that the air bulbs is the major reason for the roughness of the sidewalls 为降低co _ 2激光加工pmma材料储液池侧壁粗糙度,本文根据传统的热传导方程,假定激光强度为高斯分布,对有限厚板状材料的温度场进行分析;并考察侧壁表面熔化层凝固过程的特征;结果表明,侧壁粗糙度形成的主要原因在于侧壁表面熔化层凝固前气泡未及时析出。
From the work of later dividing and isochronous tracing correlation of sands , analyse the structure of reservoir , the results display that there are two kinds of structure of reservoir in this area : the major is platelike synthesis and the minor is maze in form . apply the synthetical analysis of the theory of high - resolution sequence stratigraphy and sedimentary dynamic , analyse the type 在层序划分和砂体等时追踪对比的基础上，对胜一区沙二段1 - 3砂组进行储层结构分析，认为胜一区沙二段1 - 3砂组以发育拼合板状储层结构为主，次为迷宫状储层结构。
