| 随钻方位电磁波电阻率测井仪器实现地层方位电阻率测量和地层层界面检测的关键在于测井仪线圈系结构的设计,且测井仪器的检测性能主要受电磁波信号发射频率、线圈源距、线圈间距、线圈倾角以及所测地层电阻率的影响。针对随钻方位电磁波电阻率测井仪器的不同检测要求，确定测井仪器的检测方式。根据线圈系结构在不同检测方式的条件下所满足的约束条件，采用仿真实验的手段设计随钻方位电磁波电阻率测井仪的线圈系结构，为实际工程应用中线圈系的结构设计提供参考依据。 |

| The key point of azimuthal propagation resistivity logging while drilling focuses on the structural design of the coil system. And the detection performance of azimuthal propagation resistivity LWD is mainly affected by the transmission frequency of electromagnetic wave signal, the transmitter receiver spacing, the receiver interval, the coil’s angle and the formation resistivity. The testing method of measurements is determined with different inspection requirements of azimuthal propagation resistivity LWD. According to the various constraints of the coil system under the condition of different testing method, the structure of the coil system for azimuthal propagation resistivity LWD is designed by experimental simulation method. The results provide reference for the structural design of the coil system for azimuthal propagation resistivity LWD. |
