摘要
通过对Taq Taq油田裂缝性碳酸盐岩油藏进行数值试井与解析试井的对比分析,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 have been used on fractured carbonate Taq Taq oilfield,and the results show that the well test interpretation has ambiguity.Even the log-log curves match completely;the interpretation may be different from the real well production.Compared with the conventional analytical method,numerical well testing technology has unique advantages on complex boundary and heterogeneous reservoirs and it can comprehensively analyze the well test dynamic evaluation and static geology study and get a visual reservoir property model.When considering the change of reservoir thickness and oil saturation,with the intensive understanding of the present reservoir performance,the interpretation of numerical well testing technology is more insistent with the real reservoir and has better application prospect.
