Phương pháp thăm dò điện trở suất là một trong những phương pháp địa vật lý được sử dụng phổ biến nhất. Phương pháp này sử dụng các loại hệ điện cực khác nhau tùy vào mục đích và điều kiện thi công thực địa, mỗi loại hệ điện cực có ưu và nhược điểm riêng. | Giải ngược tổ hợp tài liệu của các hệ điện cực trong phương pháp điện trở suất 2D 52 Journal of Mining and Earth Sciences Vol. 61 Issue 1 2020 52 - 60 Inversion of multiple data sets acquired by different array configuration of geoelectrical resistivity method Thong Duy Kieu Faculty of Oil and Gas Hanoi University of Mining and Geology Vietnam ARTICLE INFO ABSTRACT Article history The geoelectrical resistivity method is one of the most commonly used Received 15th Dec 2019 geophysical methods. This method uses different electrodes configuration Accepted 6th Jan. 2020 electrode array depending on the purpose and conditions of the field Available online 28th Feb. 2020 each type of array has its advantages and disadvantages. Due to the Keywords development of data acquisition technology it is common for Inversion geoelectrical instruments enable to record data arising from different electrode arrays with negligible real-time construction. However current Resistivity software s only allows to process for each individual electrode array. Integration Inverted models of different electrode array can be integrated to build a Electrode array. common earth model. However due to the nature of the geophysical inversion is non-unique solutions it means that there will be an infinite of models that can be suitable for a measurement in a certain noise level. This leads to the same measurement data in an area with different electrode array may produce different geoelectrical models making the dificulty for integration process. To solve this problem we utilise the simultaneous joint inversion algorithm of data sets arising from multiple electrode arrays. The test results on synthetic data show that this combination is better than the solution of each individual electrode array. The best result is a combination of pole - dipole PD dipole - pole DP and dipole - dipole DD . Copyright 2020 Hanoi University of Mining and Geology. All rights reserved. Corresponding
