地质体单元边界的自动搜索技术探讨

AN AUTOMATIC BOUNDARY SEARCHING METHOD OF GEOLOGICAL OBJECTS

地质体边界数据是油藏数值动态模拟、盆地模拟、油气分布预测等应用的基础数据。过去 ,地质工作者通过地质图或有关剖面图对地质体边界单元数据进行提取 ,这种方法不便于数据的自动采集和计算 ,且工作量极大。作者应用八方向测试算法和改进的左方向技术 ,用 VisualC++语言编程并实现二维地质体单元边界的自动搜索。该方法对松辽盆地某剖面数据进行实际运算和处理 ,结果表明效果良好 ,值得推广。

Geological objects boundary data is the base data for the animate simulating of oil pool numeric, basin simulate and oil gas distribution prediction etc. Geological scientists used to obtain boundary data by using geological maps or section with lower accuracy. Exploiting Eight Direction algorithm and Left Direction technology the author propose an approach of automatic searching geological objects boundary by 2D grid method and its application program in Visual C ++ . This approach has proved effective when used to calculate and process the section data of SongLiao basin, hence it is worthy for recommending.
