| Abstract: | The natural GR radioactive signal detection is a main aapproach used in oil exploration and production.It can be used to determine the type of clay and clay content,identify the lithology,and correct the depth for other logging job.GR signal detection can be achieved using PMT drived high performance,high-voltage power amplify,threngh the faint GR signal in the formation detected by scintillation crystal.The paper specially designs a high-voltage switch power using for PMT in the GR tools.The power work under the PWM model has the properities of small bulk,high efficiency and stablization in working.The power has passed the test and applied in daily operation. |
