The study on a new technology of waterway information system

It is a lot limitations to survey and design waterway by the CAD technique,due to timely variation of hydrology and ecology in the complicated estuary area,such as Changjing River estuary.In this paper,the advantages of GIS technique is applied to manage and process the multi kind,multi scale and multi time hydrographic parameters,including water depth,current velocity,tidal,waves,wind speed,temperature and salinity etc.,also to deal with different projection,different scale charts.Meanwhile,in the paper,combination techniques of GIS and CAD has been developed for unification of the charts for efficient management,two-way automatic carts conversion between GIS and CAD,automatic cutting and assemble of a number of Charts,flight path of the projection of spatial data and coordinate transformation.This new technique has been applied to survey and design waterway of Changing River estuary.The result shows that the combination technology of GIS and CAD has application potentiality in the waterway survey and design.     

The application of geographic information technology to coastal geomorphology

With the development of modern oceanic observation technologies,coastal survey data have been experiencing a substantial growth.The integration management of the data from different disciplines,different sources and different formats has become a major research field in coastal geomorphology by using Geographic Information System (GIS).This paper puts forward a new methodology framework of GIS techniques in coastal ocean geomorphology,including data acquisition,process,analysis,and representation.It focuses on some major GIS techniques to study the land-ocean interaction mechanism,such as spatial analysis,submarine topography model and three-dimension (3D) visualization,and apply its result to coastal urban planning,harbor site selection and geomorphology environment about coral reef and islands on the continental shelf.The case studies cover the whole coastal ocean to serve the social community,economical development and diplomatic rights for decision-making all round in the coastal zone.The research shows clearly that the application of coastal multi-source geospatial platform has changed the traditional coastal geomorphology science dramatically from its research scope,fields and methods,however,as made clear in this paper,extracting accurate information from remote sensing data and GIS databases for coastal geomorphological applications is a nontrivial challenge that requires the combined knowledge and skills of information scientists and geomorphologists.     

松辽坳陷湖盆环状坡折带发育特征及对沉积过程控制

借助高精度层序地层学、构造地层学、精细沉积体系分析和构造-古地貌恢复的理论和技术手段,对坳陷期松辽湖盆开展了整体性和综合性的再评价。研究认为,拗陷期影响和控制松辽盆地沉积过程的最主要因素是环古松辽湖盆发育的内环坡折带和外环坡折带。可划分为两大类型,即张扭性和压扭性。张扭型坡折以泉头组为代表,压扭型坡折在姚家组最典型。它们各自控制着不同的沉积过程。在此基础上,建立了具有典型代表意义的古松嫩平原沉积模型和古松嫩湖泊三角洲沉积模型。提出了以内、外环坡折为基础的有利勘探方向。     

Geochemical overview and undiscovered gas resources generated from Hamitabat petroleum system in the Thrace Basin,Turkey

Since the first drill in 1957, three oil, 19 gas and condensate fields have been discovered in the Thrace Basin. However, any petroleum system with its essential elements and processes has not been assigned yet. This study consists of two parts, (1) geochemical overview of the previous work in order to get a necessary help to construct a petroleum system and (2) calculation of quantitative undiscovered hydrocarbon resources generated from this system. An extensive overview study showed that the primary reservoir and source rocks in the Thrace Basin are the Middle Eocene Hamitabat sandstones and shales, respectively, hence it appears that the most effective petroleum system of the Thrace Basin becomes the Hamitabat (!) petroleum system. Currently, 18.5 billion m³ of in-place gas, 2.0 million m³ (12.7 million bbl) in-place waxy oil as well as minor amount of associated condensate were discovered from this system. This study showed that the regional distribution of the oil and gas fields almost overlapped with the previously constructed pod of active Hamitabat shales implying that short and up-dip vertical migration pathway of hydrocarbons from the source to trapping side was available. Thermal model demonstrated that hydrocarbon generation from the Hamitabat shales commenced in the Early Miocene. The amount of quantitative gas generation based on the mean-original TOC = 0.94 wt%, mean-original HI = 217 HC/g TOC and the volume of the pod of active source rock = 49 km³ is approximately 110 billion m³ of gaseous hydrocarbons that results in a high generation–accumulation efficiency of 17% when 18.5 billion m³ of already discovered hydrocarbons are considered.
