Proposed are regional correlation method and mixed formation water method of complex lithology for interpretating pay zones with low resistivities in this oilfield.
提出了利用区域对比法和复合岩性混合地层水法评价该油田的低电阻率油层,克服了原解释时仅利用单井资料进行低电阻率油层评价过程中存在的不利因素;在资料标准化以后,利用回归分析技术建立岩电关系图版,包括孔隙度与声波、中子、密度测井的关系图版;渗透率与孔隙度的关系图版;根据试油分析资料和测井典型分析层段建立油气水判别标准。
Key strata is a rock seam which plays an important controlling roles in the movement of mining overlayer strata while the key strata is sometimes made up of two or more compound rock strata.
在采场覆岩运动中起主要控制作用的岩层为关键层,而有时关键层是由2层或2层以上岩层形成的复合岩层所组成,我们称其为复合关键层。
It is mainly to research the compound karst developmental mechanism between the two soluble rocks,which are involved in the chemical karstification and the biological karst processes.
文章主要从自然条件上研究两者复合岩溶发育的机理,探讨了化学岩溶作用过程和生物岩溶作用的机理。
Based on the experimental study of the compound rock s behavior at rock salt s over-layer under single compression and tri-axial compression condition, the basic mechanical properties of the rock have been obtained.
通过对岩盐矿体顶板复合岩石力学性质单轴受力状态和三轴受力状态下试验研究,得到了岩盐顶板层状复合岩石的基本力学特性,可为有关科学研究和生产实践提供参考依据。
On the background of ShuiBuYa Project,by means of FLAC,the field pressure-bearing slat tests on compound rock mass includingsingle soft rock formation are simulated by computer.
本文以清江水布垭工程为背景,采用FLAC方法,对合单一软岩层的复合岩体进行了现场承压板变形试验的计算机模拟,研究了软弱岩层埋深、变形模量以及承压板直径对复合岩体宏观力学参数的影响。
