The management work data of oil - field earthquake exploration and oil - well position, which has not only data of current space position, but also entitative attribute data describing, have great capacity, traditional cad graphics describing the data plus the model database managing mode ca n ' t already adapt the modem exploration with well geography information for management work demand, so it is necessary to realize the unique management of exploration and oil - field well space data and attribute data use advanced geography information system ( gis ) technique, this thesis is based on the excellence ' s table ' s top geography information system - the maplnfo software, using the second process technique, the digital relief map and tectonic map as the base map, the earthquake exploration database as the original data, established the gis of the exploration and oil - field well in the area of the liaohe oil - field, realize visualization management, it provides a reference thereunder for the earthquake exploration deplo ying the workload and proceeding the technique design, and completed lots of practical work
油田地震勘探與油井井位管理工作數據量大，既有空間位置數據，又具有實體的屬性描述數據，傳統的cad制圖+屬性數據庫管理模式已經不能適應現代勘探和井位管理工作的需要，採用先進的地理信息系統（ gis ）技術，實現勘探和油田井位空間數據和屬性數據的統一管理是必然的趨勢。本文以優秀的桌面地理信息系統mapinfo軟體為開發平臺，在此基礎上進行二次開發，以數字化地形圖、構造圖為載體，以地震勘探數據庫為數據源，建立了遼河油田范圍內的地震勘探和油田管理信息系統，實現了數據的可視化管理，為地震勘探部署工作量、進行技術設計，提供了圖形和數據的參考依據。並完成了很多實際工作。 -
