摘要
以扎格罗斯盆地Taq Taq裂缝性碳酸盐岩油藏为例,对数值试井与解析试井进行了对比分析,说明了试井解释具有多解性,双对数曲线形态即使完全拟合,其解释结果也可能与井的实际情况不符。与常规解析方法相比,数值试井技术在处理复杂边界、非均质油藏问题方面具有独特的优势,可以综合分析试井动态评价成果和静态地质研究成果,获得一个直观的油藏属性模型,考虑油层厚度、含油饱和度的变化因素,深化对目前油藏动态的认识,解释结果更加符合油藏的实际情况,具有良好的应用前景。
Both numerical and analytical well testing methods were used in fractured carbonate reservoirs in Taq Taq Oilfield,the results were contrasted.It shows that the well test interpretation has ambiguity.Even the log-log curves match completely;the interpretation may be different from actual well production.Compared with the conventional analytical method,numerical well testing technology has unique advantages on complex boundary and heterogeneous reservoirs and it can be used for comprehensively analyzing the well test dynamic evaluation and static geology study,by which a visual reservoir property model is established.In consideration of the changes of reservoir thickness and oil saturation,the deep understanding of the present reservoir performance is realized,the interpretation of numerical well testing technology is more insistent with the real reservoir and it has better application prospects.
