储层预测技术在塔河喀斯特岩溶缝洞型油藏开发中的应用

Application of the Reservoir Prediction Technology in the Reservoir Development of Carbonate Karst in Tahe Oilfield

在塔河喀斯特岩溶区通过大时窗振幅属性提取技术进行缝洞体空间描述，平面上结合古地貌、趋势面区分地表水系，刻画深部地下暗河在平面上的展布规律，为勘探、开发井的选定提供充分依据，降低油田勘探开发的风险，取得了较好效果。

Extraction technology of large window amplitude attribute, for the first time, was applied to describe and predict the Carbonate karst cave in Tahe Oilfield in this paper. Utilizing the ancient landform and trend surface, it could distinguish between surface river and underground river.The distribution regularities of underground river could be de- scribed in the plane.More adequate basis were provided for selected exploration, development well, and the risk reduced about oil field exploration and development by this more effective method.
