摘要
为了对煤层气勘探目标区的优劣作出较为正确的评价,文章以地理信息系统(GIS)空间数据库技术为核心,在计算机软硬件的支持下,应用于空间和地理有关的数据的采集、存储、提取、检索、分析、显示、制图,实现综合管理和分析应用。文章以全国煤层气勘探目标区为研究对象,利用GIS将目标区的地质空间要素与统计数据有机地结合在一起输入数据库,采用风险概率法和综合排队系数法直接用于煤层气勘探目标区优选。其技术关键包括资料采集、数据库的建立、因素指标集的构建、定量化数学评价模型及其计算机实现。其优选结果具有现时性,对煤层气的勘探开发具有一定的指导意义。
The comprehensive management, analysis and application and the correct evaluation of coalbed methane exploration target area may be realized by applying the space database of geographic information system (GIS) to the data gathering, memory, access, retrieval, analysis, display and mapping related to the space and geography. By taking all the coalbed methane exploration target areas in China as the research objects, and by the aid of GIS, the geological space elements and statistic data of the target areas were inputted the database to optimize the target areas directly by use of the risk probability method and integrated queue coefficient method. The technical keys include the data acquisition, the establishment of database, the determination of factor index set and the establishment of quantified mathematical evaluation model and its being realized by computer. The optimized results are of a certain importance to the coalbed methane exploration and development.
