| 摘 要： | 碳酸盐岩储层预测一直为世界性难题。塔河4号油田奥陶系碳酸盐岩储层以岩溶、构造运动形成的溶蚀孔洞和裂缝系统为主，具有埋藏深，非均质性强的特点。文中对利用测井约束反演进行储集层预测的方法进行了探讨，通过初始波阻抗模型的建立、合成地震记录标定、子波提取和薄层识别等技术，结合本区特点，对碳酸盐岩储层进行了追踪、预测，提高了碳酸盐岩储层预测的可靠性，获得了较好的应用效果。

| Abstract: | Prediction of carbonate reservoirs is a cosmopolitan problem. The Ordovician carbonate reservoirs in Tahe 4 oilfield are dominated by vugs and fracture systems caused by karstification and tectonic movement, and characterized by deep bury and strong heterogeneity. The paper approaches method for reservoir prediction by using logging constrained inversion technique, traces and predicts carbonate reservoirs through techniques of building of initial wave impedance model, calibrating of synthetic seismic section, wavelet picking and thin layer identification etc, combining characters of the region. Desired results with improved reliability have reached. |
