摘要
磁定位仪器作为石油测井用的主要校深仪器,在检验深度误差方面发挥着重要的作用.按照磁定位信号的不同将仪器分为四类进行介绍:无源磁定位信号、有源磁定位信号、调制磁定位信号和数字磁定位信号,同时以抗震磁定位仪CCL,抗震磁定位伽马仪736XA,磁定位伽马仪WGC10、石英压力磁定位仪QPC四种不同仪器为例对磁定位信号电路进行原理分析.
Abstract
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.
