应用GIS技术辅助油藏管理

APPLYING GIS TECHNOLOGY TO AID RESERVOIR MANAGEMENT

油气藏开发涉及油气藏的三维空间分布和内部状态变化的复杂问题 ,信息系统是支持油藏管理的基本手段。传统油气藏开发管理信息系统基于表格形式表现对象属性 ,无法反映描述对象的空间联系和系统的空间分布模式。地理信息系统 (GIS)能够有效描述二维空间问题 ,将GIS技术引入油气藏开发管理信息系统将极大地扩展管理信息系统的描述能力和表现形式 ,但是对于油气藏开发这类特殊的三维问题还缺少描述和分析能力。通过分析传统的油藏管理信息系统所面临的问题 ,提出了油气藏开发管理GIS系统的体系结构、目标设计和功能设计 ,讨论油气藏开发管理GIS系统的技术路线、信息组织方式、表示方式以及开发模式 ,指出需要研究更完善的三维空间描述方法和表现手法 ,结合油藏描述技术及其成果 ,在地质建模的基础上开展空间分析 ,将会使油气田开发中的GIS技术更加完善。

Process of reservoir exploitation is involved in complex problems of three-dimensional spatial distribution and inside variation. The information system is the basic means of administering reservoir management. The traditional reservoir management information system is based on tabular forms to show properties of objects, it can't reflect the spatial relations and spatial distribution patterns. Geographic Information System (GIS) can effectively describe two-dimensional problems. The GIS technology led in reservoir management information system will greatly expand its descriptive abilities and representative styles, but it is short of descriptive and analytic ability about the three-dimensional special problems, such as reservoir exploitation. This paper analyses the problems that are faced by traditional reservoir management information system. The reservoir management GIS system with system structure, target design and function design is presented, The technologic way, information organization, representation and development model are discussed. Three-dimensional spatial description and representation need to be enhanced for GIS in reservoir exploitation. Combined with application result of reservoir characterization, GIS will be improved by spatial analyses based on geologic model.
