水平井射孔方位检测技术

Technique of Checking the Perforation Azimuth of Horizontal Wells

针对水平井射孔问题，论述了水平井射了孔前准确检验核实射孔方位的必要性，介绍了水平井射孔方位角检测方法、电路原理以及把检测出来的方位信号传输至地面的技术问题．

This paper expounds the necessity for checking the exact perforation azimuth of horizontal wells and introduces the checking method,the circuit principles and techniques concerning the transmission of the checked azimuth signal from downhole to the surface.
