石油测井目前已发展到能谱测井阶段,相应要求能谱型高温光电倍增管与之配合。GDB-59型光电倍增管是一种新型150℃高温光电倍增管。经实测证明,该管型达到了国际上同类型高温管的水平。
Oil logging has now progressed to the spectrum logging stage, corresponding to the energy spectrum of high temperature photomultiplier tube with it. GDB-59 photomultiplier tube is a new 150 ℃ high temperature photomultiplier tube. The measured proved that the tube reached the international level with the same type of high temperature tubes.
