Design and Application of Network Borehole-Ground Electrical Measurement System

Abstract:

Borehole-ground Electrical measurement is an important geophysical exploration method to determine the underground distribution of remaining oil. The author designs a set of network measurement system, where the intelligent electrodes were arrayed. Potentials are measured continuously to realize the dynamic monitoring. We adopt multi-channel simultaneous sampling and linear accumulated digital averaging to suppress electromagnetic noise. Feedback compensative method is used to exclude the influence of SP (spontaneous potential) and covers a wide dynamic measurable scope. In order to make all measurements validity, all electrodes earthing situation are collected. We present the oilfield survey data measured by this self-developed instrument. Practical application shows that the system is characterized with high efficiency, portable and strong anti-jamming capability.
