| 摘 要： | 笔者在郯庐断裂带、苏北盆地和珠江口盆地等区,运用有限元平面应变—应力分析、计算出的应变—应力场基本符合该区地质情况,此方法用于区域构造研究中是可行的。我们在含油气盆地区开展这一研究,把地球物理资料转化为半定量的应变一应力场分析,使地球物理资料再次开发和利用,对盆地的区域构造和含油气特征有进一步的认识。

| Abstract: | In this paper the authors summarize the study of the application of the finite elementplane strain-stress analysis to the Tancheng-Lukiang Fault Zone,Northern Jiangsu Basinand Pearl River mouth Basin.The result indicates that this analysis used in the study ofthe regional tectonics is rational,because when rational boundary conditions are selected,the calculated strain-stress fields conform with their regional geological characters.Much work also has been done abroad.This method has been used in the oil and gas containingbasinsby converting the geophysic data into the semi-quantitative strain-stress data,whichspends little money,but the geophysic data can be used once more.The popularization ofthis method will raise the study of regional tectonics to a new level.l |
