GIS在油气田开发管理系统中的扩展实现

Extended realization of GIS in development and management system of reservoir

由于油气田的开发与空间地理位置密切相关,因而可以在油气田开发管理过程中引入GIS技术.但是油气田开发又具有其特殊性,油气田开发管理GIS除了必须具备基本的GIS功能外,还应采用其他技术来扩展GIS的表现方式,弥补现有地理信息系统在展示方面的不足,进一步完善油气田开发管理地理信息系统.主要从地图投影转换、图层叠加、三维地质模型、地图浏览回放几个方面来阐述如何利用其他技术来实现GIS在油气田开发管理中的扩展.通过对油气田开发管理中GIS技术进行扩展,极大地丰富了地理信息的展现形式,使信息的展示更加直观、形象,增强了GIS的三维空间描述能力和表现手法,将GIS单纯的信息系统发展成为管理与决策支持系统.

Owing to the close correlation of development of reservoir and spatial geological place, the technology of GIS can be introduced into the process of development and management of reservoir. But, development of reservoir has its particularity, so, development and management GIS of reservoir should use other techniques to extend the forms of representation, make up the shortages of GIS in representation and more perfect development and management GIS of reservoir besides the basic functions of GIS. This paper expatiates how to use other techniques to extend GIS in development and management in reservoir mainly from map projection transformation, layers of map piling up, and three-dimensional model to repeating playing maps, etc. Through extending GIS of development and management in reservoir, the forms of representation of geological information are enriched, representation of information is more direct and visual, spatial descriptive ability and forms of representation of GIS are built up and the single information system will be developed into a management and decision-making system.
