| 摘 要： | 井洞影响是井径变化地层致使阵列感应测井响应曲线出现异常的主要原因。在建立井洞影响计算模型基础上，利用Gianzero几何因子计算阵列感应测井井洞响应并对井洞影响进行校正。结果表明：这种方法能够有效的减小井洞影响，使得出现井洞的异常测井曲线趋于正常。应用高数中拐点与极点的知识，确定了可处理井洞的位置以及数值模拟所需的地层模型参数。地层模型井洞影响校正实例验证了井洞影响校正数值模拟结果的有效性。

| Abstract: | The cave effect is the main factor which results in the abnormity of array induction logging curves when the borehole irregularity exits.On the basis of establishing the cave effect model,the cave response of array induction logging are calculated and the cave effect is corrected by Gianzero geometric factor.The results show that the way can effectively lower the cave effect and make the abnormal curve with the caves to be normal.The location of the normal caves and model parameters for numerical calculatio... |
