借鉴现代水系袭夺理论，证实了塔河油田四区东部岩溶流域早期为南向汇流结构，而后期由于构造运动引起西北部侵蚀基准面下降，并通过地下途径对邻近南向流域北缘进行逐步袭夺，形成了大型倒淌河，再现了本区岩溶古水系及流域的阶段性演化过程，从而为揭示塔河油田奥陶系古岩溶发育规律提供了重要的依据。

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.
