逆掩断层 meaning in Chinese
overthrust fault
overthrustfault
Examples
- Through the research on the development character of overthrust fault , we analyzed its sealing mechanism . we also established evaluation standard and method of fault sealing ability through the following two simulation experiment : experiment on the quantitative relationship between property of fracture zone filler and fault sealing ability ; experiment on the deformation character of cream shale . based on these work , we evaluated sealing ability of overthrust faults on several typical structure in kuche depression
本文通过逆掩断层发育特征研究，分析了逆掩断层封闭机理，在断裂带填充物性质与断层封闭性定量关系模拟实验和膏泥岩变形特征模拟实验基础上建立了断层封闭性评价标准及评价方法，以此对库车坳陷几个典型构造上逆掩断层垂向封闭性进行了评价，结果表明现今断层多是封闭的，这是库车塌陷天然气和异常孔隙流体压力得以保存的主要条件。 - Based on these research , we recovered the evolution history of overthrust faults vertical sealing ability and considered that there always have fracture activity ever since jidike formation deposition period . but this kind of activity is not always continuous . during moving period , fault is open
在此基础上对逆掩断层垂向封闭性演化史进行了恢复，认为断裂自吉迪克组沉积时期以来均有活动，但这种活动是间歇性的，活动时期断层开启，静止时期断层多是封闭的。 - We established geological and mathematic model for the relief of overthrust fault and earned out simulation computation after selecting factors . the result is that pressure can be released when fault is open . but ft will take a long time for the formation pressure to be relieved to normal formation pressure
建立了逆掩断层泄压的地质模型和数学模型，选取参数后进行了模拟计算，结果表明逆掩断层活动开启释放压力，但要将地层压力释放到正常地层压力需要时间较长，在断裂活动时期不足以将圈闭中超压释放掉，这是库车坳陷超压能够保存的另一主要原因。
