palaeomagnetic meaning in English
古地磁的
Examples
- During sample preparation for palaeomagnetic reorientation , the proplem of magnetic pollution which is produced by other magnetic field should be cautions . 4
在古地磁定岩心方向时，要谨防岩心再次受到外界环境和操作过程中的磁污染。 - The original orientation ( i . e . the mol with respect to the geographical north ) of the core in the formation can be obtained by palaeomagnetic orientation tests . the two results are combined to define the direction of the maximum principle stress of the well or field
该方法根据差应变分析( dsa )实验确定地应力相对于岩心标志线的方向，利用古地磁方法确定岩心标志线相对于现代地理北极的方位，两者结合确定地应力方向。 - So far , many methods have been used for studying the in - situ direction of oilfields and every method has its advantages and disadvantages . this thesis focuses on the method that predicts in - situ stress orientation for wells using differential strain analysis ( dsa ) and palaeomagnetic orientation
目前为止，油田地应力方向的研究方法很多，每种测试技术都有其优点和局限性，本文主要讨论利用差应变分析和古地磁方法结合确定地应力方位的方法。 - The technique which predicting in - situ stress direction for wells using dsa and palaeomagnetic orientation has been applied in wide - range - - - daqing , jilin , shengli , anhui , henan , erlian , changqing , talimu and qinghai oil fields and so on . the results of application are very good
将差应变分析与古地磁岩心定向技术在国内进行了进一步的应用和推广，分别在大庆、吉林、胜利、安徽、河南、二连、长庆、塔里木及青海等多个油田进行了现场应用，应用效果较好。 - These mafic dykes may provide some important insights about the mantle processes at ca . 1800 - 1700 ma and their geodynamic implications . unfortunately , more attention has been paid to palaeomagnetic , petrologic , lithochemical and k - ar geochronological studies of these mafic dykes
该论文现在对作为华北陆块早元古代基性岩墙群重要组成部分的南太行山地区基性岩脉开展了较为系统的年代学、元素和同位素研究，以期为理解华北陆块1800ma构造背景提供新的资料。
