Product Description

 DLL dual lateral logging tool
 can be connected with 521 or DLS domestic CNC system

DLL tools  is one main methods of resistivity-logging,it include: a short section of insulation, electronic circuits, pressure-balanced fiberglass probe and the lower electrode (can be substituted by other logging instrument 's shell) 

       DLL tool can be connected with 521 or DLS and other domestic small CNC system, to  complete the combination for logging; can  provide Two different-depths lateral resistivity measurements datas. then cooperate with other logging datas, can  accurately Distinguish  permeable  horizon , oil/water  horizon , identify and evaluate the  properties of oil bearing stratum.    

     if Coordinate with other logging datas, can distinguish permeable layer directly,determine oil layer clearly , identify the water/oil layers, identify / evaluate the properties of  oil stratigraphic .
