Product Description

 DLA dual lateral logging tool of the constant power 
 

DLA constant-power laterolog is one main methods of resistivity-logging  ,it include :a short section of insulation, electronic circuits, pressure-balanced glass probe and the lower electrode (can substitute by the shell of other logging instrument shell) .

      DLA dual lateral logging adopt the  CSU-Dual-Lateral technology ,so as to be ataached with 3700 or 5700 systems directly , and can complete combination-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.

      The instrument measured the current and voltage by a certain method ,so as to control the power of different depth lateral, increased output-power and the received SNR; use double shield electrode, focusing on the main current , reduces  the affection of cable,  mud,  layer; have better capability of Distinguish different lawyers ,have much deeper investigation-depth, could measure bigger dynamic  range, high accuracy; and in the non-permeable formations ,the deep and shallow lateral curves coincidence well;  have very good radial probe characteristics; 

 

    this instrument's electrode is made of stainless steel and have glass insulating sleeve , with anti-corrosion, durability and other characteristics, suitable for a variety of stratigraphic logging, and could be disassemble easily ,is  easy maintenance.
