depositional model meaning in Chinese
沉积模式
Examples
- These geomorphic units of paleogeography constitute the basic model of paleocontinent , littoral - neritic sea and carbonate plateform at that stage , and this depositional model is similar to the pattern of the east china continent and ocean , which is the result of evolution during the past long geologic age
这些古地理地貌单元构成了湖北省泥盆纪时期古陆滨浅海和碳酸盐岩台地的基本沉积模式，这种沉积模式与现今中国东海大陆、海洋格局基本一致，亦是经过了漫长地质历史时期演化，而形成现今这种格局的。 - With regard to the causes of formation and sources of salt , people have different point of views in different basins , and different depositional models are set up , even in one same basin there are also divergent view to exist different opinions still exist on the position of the salt bearing strata in sequence stratigraphy . it will greatly influence the exploration level of resources in salt - bearing basin if the above doublts can not be made clear . in this way , it will be of great significance to make it clear about the above issues and the relationships about salt and oil & gas
对于盐岩的成因及盐源在不同盆地有不同的认识，并建立了各自的沉积模式，就是同一含盐沉积盆地或含盐沉积凹陷人们的认识依然分歧很大，关于盐岩在层序地层中的位置人们的认识依然不同，对这些问题的认识不清将极大的影响对人们含盐盆地的能源勘探开发水平，因此搞清盐岩的成因及其与油气聚集的关系具有重要意义。 - Directed by new theories and approaches of sedimentology , diagenesis and reservoir evaluation , focused on marine clastic reservoir of donghe sandstone member , in tarim basin , strata and depositional system of donghe sandstone member are classified ; typical depositional facies types , depositional model and horizontal distribution have been studied through depositional facies analysis of 17 single wells , combined with seismic data . major diagenetic events , stages and " four history " collaboration have been systematically analysesed , furthermore , the relation between reservoir diagenesis and porosity evolution has been built ; thorough studies on reservoir lithology , physical property and pore structure , reservoir development related to depositional envoironment , diagenesis and tectonic has been discussed ; reservoir has been evaluated and predicted by five influential parameters drawn from the results of the study on depositional facies , diagenesis and reservoir characteristic . in the end , favourable reservoir body distribution has been pointed out
本论文以沉积学、沉积岩石学、沉积成岩作用与储层地质学、储层评价技术的新理论新方法为指导，以塔里木盆地巴楚组东河砂岩段海相碎屑岩储层为主要研究对象，通过17口典型井的单井地层沉积相分析和成岩作用分析，结合地震资料，对东河砂岩段地层和沉积体系进行了详细划分，研究了东河砂岩段分布区的典型沉积相类型、沉积模式及其平面展布特征；系统分析了东河砂岩段碎屑岩储层的主要成岩事件、成岩期次及其四史配置关系，指出了储层成岩与孔隙演化的关系；深入研究了东河砂岩段碎屑岩储层的岩石学特征、物性分布、孔隙结构等特征，着重讨论研究了沉积环境、成岩作用和构造作用对储层发育的影响；运用“权重”评价法结合地层沉积相、成岩演化和储层特征研究的结果，选取了五个对储层发育有重要影响的参数对储层进行了整体的评价和预测，指出了塔里木盆地东河砂岩段储层有利储集体的分布状况。
