摘　　要：碳酸盐岩油藏酸化改造非常普遍,为对这类酸化井层进行测试资料试井解释,需要建立能真实反映油藏实际的数学模型和解释图版。通过建立钻遇溶洞和封闭外边界情形下试井模型,应用拉普拉斯变换和数值反演得到碳酸盐岩油藏酸化井的井底压力响应曲线,并对溶洞区和地层窜流系数如何影响井底压力响应曲线进行了研究,说明建立模型可以对这类碳酸盐岩酸化井测试资料进行解释。。Well reconstruction by acidification was widely used in carbonate reservoirs.To interpretate these wells,it was necessary to establish a practical and mathematical reservoir model and interpretation chart.The model was tested on the condition of drilling cave and closed boundary well,Laplace transformation and numerical inversion were used to get the wellbore pressure response curve of acidized wells in carbonate reservoirs,the influence of cave and cross flow factor on acidized well is studied in carbonate reservoirs.
