Introduction and Signal Analysis of Common Logging CCL Tools
CCL tools are the major depth correction tools in petroleum logging,which play important part in test depth errors.according to difference of CCL signal,this article introduces four types of tools:Passive CCL signal,Active CCL signal,modulation CCL signal and digital CCL signal,meanwhile,take for instance four different tools of Antiknock CCL Tool CCL,Antiknock CCL GR Combination Tool 736XA,CCL GR Combination Tool WGC10,Quartz Pressure CCL Combination Tool QPC,analyzes the principle of CCL signal circuit.
