| 1. | By analyzing the faulted features , faults have the characteristics of generation , successive , cycle , segment and correlation 通过分析断裂特征,提出了本区断层具有分期性、继承性、旋回性、分段性和相关性的活动规律。 |
| 2. | The upper part is a set of evaporite quasi - tidal sequence with clear cycles which is made up of middle - thin - bedded , gypsum - bearing muddy limestone and dolomicrite 上部为中薄层状富泥的含石膏质夹层的泥质泥晶灰岩、微晶白云岩组成的旋回性清楚的似蒸发潮坪层序。 |
| 3. | Cyclicity character is one of the most important attributes of depositional strata , and it looks more important in the terrestrial sediments 摘要旋回性特征是沉积岩层最为重要的属性之一,尤其在对于区域地质背景波动做出敏感响应的陆相盆地沉积序列当中更是如此。 |
| 4. | The polyphasic and episodic tectonism of these basins usually had a significant influence on the regional deposition - erosion cycles and the depositional patterns 盆地构造演化的阶段性、旋回性及多期的构造变革对盆内多旋回的沉积剥蚀过程的叠加和原型盆地的叠合等可产生深刻的影响。 |
| 5. | This variation not only results in the cyclicity of basin evolution , but also the formation of multiple oil - bearing sequence of meso - cenozoic in liaohe basin and adjacent its areas 不同区域应力场的转化不仅导致了盆地演化的旋回性,也为辽河盆地及其邻区中新生代多套含油气层系的形成奠定了物质基础。 |
| 6. | Based on the analyses of outcrops , core , log data , agrochemical information , etc . which can be recognized as delta sedimentary system in zibei oilfield , each sedimentary systematic characteristic and their genetic is analyzed carefully 在沉积体系分析的基础上,考虑到地质作用过程中的全球性、旋回性、可对比性及砂体预测的实用性等方面。 |
| 7. | Rhythmicility or periodicity of the depositional strata is influenced by the fluctuation of sea - level to a certain extent , but it must be the response of depositional course to the structural activity in extensive significance 研究表明,沉积岩层的韵律性或旋回性特征在一定程度上受海(湖)平面变化影响,但从更加广泛的意义上来看,应是沉积过程对于区域地质背景波动的响应,其主控因素是构造波动。 |
| 8. | For hydrodynamic force , the oil - gas would migrate at vertical and lateral , and accumulate at suit traps . at the same time , for hydrogeology gyrations , petroleum would periodic migrate and ringed distribute . therefore , ground fluid is at different hydrodynamic systems 同时,由于古水文地质的旋回性导致同一流体动力体系内不同流体动力系统的油气一致阶段式运移,并形成一个以凹陷为单元阶梯式一环带状的油气分布规律。 |
| 9. | Rhythmicility or periodicity of the depositional strata is materialized by the transformations of lithological characters in strata ordinally , and it is incarnated by the transformations of ingredient , granularity , color , intensity of the depositional compensation , intensity of oxidation - deoxidation , and the character of biome 沉积岩层的韵律性或旋回性特征由岩层的岩石学性质在纵向上的(随时间的)有规律变化所决定,这些变化主要由以下方面所体现,包括:组分变化、粒度变化、颜色变化、沉积补偿强度变化、氧化还原强度变化,以及化石群性质变化等。 |
| 10. | Many times structure movements of huanhua basin result in many times water progradation and retrogradation . cycle sediment in portrait and stratum lapout & denudation in plane and vary of different types sand body are resulted in sediment process . it provides better condition for subtle trap 研究表明,黄骅坳陷构造运动的多期性形成多次水进水退,在沉积上产生了纵向的多旋回性和平面上的地层超覆与剥蚀以及不同类型砂体的变化,为隐蔽油气藏的形成提供了良好条件,盆地中区是隐蔽油气藏较为集中的分布区。 |
