逆掩 meaning in English
thrust over
thrust up
Examples
- Depending on the intensity of the deforming forces the folds may be gentle, sharp, overturned, or overthrust .
根据变形力的强度,褶皱可以是平缓的,陡峭的,倒转的,或逆掩的。 - The frontal structure of longmenshan in the west of sichuan is very complex , showing intense structure deformation in overthrust belt , high structure amplitude , steep stratigraphic dip , developed fault blocks , complex seismic wave field , frequent change of lateral velocity , and poor image of post - stack time migration processing
摘要川西龙门山前缘构造非常复杂,逆掩推覆构造带构造形变强烈,构造幅度大,地层倾角陡,断块发育,地震波场复杂,速度横向变化大,常规叠后时间偏移处理成像效果较差。 - 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。 - To do the investigating and studying work about the achievements of tackling key problem of the quondam exploration of front - zone of mountain , to analyze and study the applicability about the gathering technology used in the seismic exploration of the complicated construction belt of front - zone of mountainous ; 2 . combining the quondam achievements , researching the design method of observation system objective of the complicated construction belt based on seismic - geology model , firstly , building the surface level and deep layer seismic - geology model of complicated construction belt and analyzing the forward model , secondly , designing the observation system aiming at the overthrust nappe structure in section and in area ; 3 . aiming at the complicated earth ' s surface condition of front - zone of mountain , how to select the exciting method and the parameter , how to optimize the environment of exciting method and reception , how to pledge the normal combination of the datum of different exciting method ; 4
根据山前带的地震地质条件特点,本文主要研究了以下几个方面的内容: 1 、对以往山前带地震攻关成果开展调研工作,分析研究在山地山前复杂构造带所采用的地震勘探采集技术的适用性; 2 、研究基于地震地质模型的复杂构造带观测系统目标设计方法:如何建立复杂构造带的表层、深层地震地质模型,利用正演分析目标区的观测系统;针对逆掩推覆体构造,如何分区分段有针对性设计观测系统等; 3 、针对复杂地表条件的山地山前带,如何选择激发方式、参数,如何优选激发、接收环境,如何保证不同激发方式的资料能正常拼接; 4 、山前带巨厚砾石区的表层结构调查技术及静校正方法研究。 - 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。
