摘要
感应测井是低频电磁场测井 ,不同的发射频率对感应测井响应的影响很大。这主要表现在传播效应、探测深度和接收信号的信噪比等方面 ,并且发射频率选择不当也会导致测量精度的降低。因此采用合适的发射频率是得到良好感应测井响应的一个重要因素。文章分析了感应测井响应与发射频率的关系 。
Induction logging is one of electromagnetic logs with low transmitter frequencies.Different frequencies have significant influence on induction responses,especially on propagation effects,depth of investigation and signal to noise performance,Moreover inadequate frequencies reduce measurement precision.Therefore,adequate frequencies are very important to good induction response.The relation between induction responses and transmitter frequencies is described,and the method of choosing adequate frequencies is suggested.
