Well to ERT Front-End Sensor-Based Design Production

Resistivity oil-water interface imager ( well to ERT ) is applied to the remaining oil in mining, according to water and oil interfacial resistivity changes to determine the fracture trend, and for the remaining oil exploitation to provide technical supports. In order to realise long-term telluric recordings correctly, and through receive cable, NI acquisition card, and ultimately sent back to the receiver, and have good resistance matching to the next step of data processing. Electrodes is one of measuring some physical quantities to distinguish the ability to directly determine the accuracy and reliability of the inversion. The use of very stable electrodes is necessary.
