摘　　要：文中应用地震、钻井、测井等资料,运用多时窗、多属性暗河预测技术,在塔河油田主体区识别出了5个暗河系统,并对暗河发育特征及油水分布特征进行了研究。结果表明:深部暗河与浅层暗河是不同时期的岩溶产物,空间继承性差。浅层暗河呈网状,充填几率大;深部暗河系统呈线状,不充填。深部暗河与浅层暗河具有独立的油水系统,各暗河系统内油水差异性分布。分支暗河、深部暗河也是优质储量发育的井区,具有勘探开发潜力。By using seismic, drilling and logging information, and multi-window muhi-anribute technology for river prediction, five ancient underground river systems are identified in the main region of Tahe Oilficld, the characteristics of oil-water distribution and river development are studied. The results show that the deep and shallow underground rivers are the karst products of the different period, their spatial inheritance is poor; shallow river is reticular, filling probability is big, and deep river system is linear, not filling; deep river and shallow river have independent oil-water systems, and the distributions of oil and water in the underground river system are different; the high quality reserves areas of potential exploration and development are distributed in the branch river and deep river.
