CO_2—ECBM地质空间数据库建设方法研究

Research of construction method of geological spatial database for CO_2-ECBM

针对CO2-ECBM煤层气开发技术实施面临多源、多尺度、多类型数据管理与分析问题,基于GIS提出了一种CO2-ECBM地质空间数据库建设方法。首先按照需求通过区域与矿井地质调查、钻孔工业测试分析等方式获取数据,然后对获取的数据进行细化、空间参考共享和分类编码,最后按照Geodatabase数据模型存储数据,从而实现了数据的共享、管理及可视化和应用分析,为CO2-ECBM技术实施提供了决策支持。

In view of problems of management and analysis of data with multi-source,multi-scale and multi-type existed in implementation of CO2-ECBM coal bed methane development technology,a construction method of geological spatial database for CO2-ECBM based on GIS was proposed.Firstly,data is obtained through geological survey of area and mine and drilling industrial testing analysis according to demand of CO2-ECBM technology.Then,the data is refined,shared in spatial reference,classified and coded.Finally,the data is stored according to Geodatabase data model,so as to realize sharing,management and visualization and application analysis of the data,and provide decision support for implementation of CO2-ECBM technology.
