The dissertation details the functions and characteristic of curves graph element, polygon graph element, character graph element, dimension graph element, parameter graph element, self-define graph element, and research comprehensively the methods describe and graph element attrib. After discussing the basic graph element collection, this thesis gives the description method, organization way, graph element visitation, save and load efficiency, suitability and so on of every element in the basic graph element collection in greater detail. The author provides a graph element data structure organized version which is length changeable and is a block storage record, and designs a new module of data, which can process both the geometry attrib and no geometry attrib of drawing element. Based on this, the data model of all kind of element is put forward.

对采矿CAD系统中基本图元集的构造原则和组织方法进行了研究，提出了一个7元素采矿CAD基本图元集构造方案；论文详细讨论了曲线图元、字符图元、尺寸标注图元、多边形图元、参数图元、自定义图元在采矿CAD系统中的作用和特点，并对各种图元的表述方法和图元属性及相应的库组织方式、存取效率进行了深入的研究，提出了一个&可变长记录块&图元库结构组织方案；通过对采矿CAD系统中基本图元数据模型的构造方法、存取结构和访问方式的研究，给出了一个用C++语言描述的采矿CAD系统基本图元数据模型及其数据存取结构。

Based on these and followed by proper reservoir classification and characteristics analysis,this paper established the methods for reservoir description of subtle pool with complex fault blocks,by which the main trap within the belt could be divided into fault block trap,structural trap and subtle trap which includes sand lens trap,lithologic updip thinning out trap,structural-lithologic trap and fault lithologic trap. For self-confined fault controlling oil flow,its height of oil column can be estimated by utilizing R.R.

在此基础上，通过油藏的具体分类和特征分析，建立了复杂断块隐蔽油藏的储集层和油藏描述方法；将东营凹陷中央隆起带中的主要油气藏划分为断块圈闭、构造圈闭和隐蔽圈闭，其中隐蔽圈闭包括砂岩透镜体圈闭、岩性上倾尖灭圈闭、构造-岩性圈闭、断层-岩性圈闭四类；提出在控油断层自密封的情况下，油藏高度可采用R.R。
