摘　　要：缝洞型碳酸盐岩油藏储集体非均质性强,连通关系复杂,油水界面不统一,储量评价难度大,导致措施成功率低,开发效果差。利用丰富的动态资料,根据有封闭水体的缝洞型碳酸盐岩油藏的特点,改进物质平衡方程,并与预测静态储量相结合,提出一种此类油藏的动态储量评价方法。该方法在不掌握油藏的油水界面位置和无实测PVT资料的情况下,能较为准确地计算原油动态储量和水体体积,在塔里木盆地哈拉哈塘油田取得了较好的应用效果。The fractured⁃cavity carbonate reservoirs are characterized by strong heterogeneity,complex connectivity and non⁃uniform oil⁃water interface,which lead to the difficulties in reserves evaluation and poor development effect.Using dynamic data,the paper improves the material balance equation according to the characteristics of the fractured⁃cavity carbonate reservoirs with closed water,then proposes a dynamic reserves evaluation method for this kind of reservoirs by combining with the predicted static reserves.The dynamic oil reserves and the water size can be accurately calculated with the method under the conditions without oil⁃water contact location and measured PVT data of reservoirs.Good application effects have been gained in Halahatang oilfield,Tarim basin.
