| 摘 要： | 塔河油田经多期构造及古风化岩溶作用，属于非均质性较强的裂缝、溶洞性复杂碳酸盐岩油气藏。研究其井间连通性，对于划分开发单元，进一步提高奥陶系油藏开发效益起着至关重要的作用。利用动态生产资料，通过Orkiiszewski方法计算井底流压，最终计算和评价油井产能系数，分析井间连通性。该方法的研究结果与静态地质分析相符，应用中与其他资料研究相互验证能够更加准确地划分储集层连通单元。

| Abstract: | Tahe oilfield undergone multi-stage tectonic evolution and paleo-weathering karstification belongs to a fractared-vuggy carbonate field with strong heterogeneity. To study its interwell communication or connectivity is greatly helpful to classifying the development block and further improving the development performance of Ordovician reservoir. By means of dynamic production data and Orkiszewski method for bottom hole pressure calculation, the formation conductivity is estimated and evaluated, the interwell connectivity is analyzed. The result is consistent with static geologic study. And this method, integrated with other available data, can be used to more precisely classify the connected blocks of reservoir. |
