2D And 3D Electrical Resistivity Tomography System Ert to Do Dipole Dipole Schlumberger And Wenner Survey Equipment for Underground Resistivity Imaging
WDJD-4 resistivity/IP meter designed the receiver and the transmitter in one unit, which support 1D Resistivity and 1D Induced Polarization VES survey;it features multiple functions, high accuracy, fast speed, high reliability and excellent expandability. Measured data of WDJD-4 can be processed by other multi-electrode resistivity software, which makes the interpretation more convenient.
Compared with the conventional resistivity method. The high-density electrical method has the following advantages:
(1) The electrode layout is completed at one time, which not only reduces the failure and interference caused by the electrode setting, but also lays the foundation for rapid and automatic measurement of field data.
(2) Scanning measurements of multiple electrode arrangements can be performed effectively, so that a wealth of geological information about the structure characteristics of the geoelectrical section can be obtained.
(3) Field data collection is automated or semi-automated. Not only is the collection speed fast (approximately 2 to 5 s per measurement point), but errors due to manual operation are avoided.
(4) The data can be pre-processed and the profile curve shape can be displayed. After offline processing, various results drawings can be automatically drawn and printed.
(5) Compared with the traditional resistivity method, the cost is low, the efficiency is high, the information is rich, and the explanation is convenient.
In addition, with the development of geophysical inversion methods, the resistivity imaging technology of high-density electrical data has also developed from one-dimensional and two-dimensional to three-dimensional.
