DLL dual lateral logging tool
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 .
