Problems solved by technology

[0005] In addition, most of the above measurement systems use the receiving and transmitting electrodes as the same electrode. After the previous electrode point is used as the transmitting electrode, a relatively large electrode charge will remain on the ground. At this time, when the next point is measured immediately as the receiving electrode, The receiving signal will superimpose the signal of the electrode charge discharge, resulting in a large drift of the receiving electrode signal, and the measured result will have a large measurement error
Some instruments use a delay method to allow the electrode to be fully discharged before measuring, which will further increase the measurement time and seriously reduce the measurement efficiency

Embodiment Construction

[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] A high-density alternating current and direct current excitation system is composed of a measuring host, a multi-channel electrode converter, a receiving cable, a transmitting cable, a receiving electrode, a transmitting electrode and an adapter wire.

[0032] The multi-channel electrode converter includes 4 interfaces, as shown in the figure, they are AB1, AB2, MN1, and MN2. AB2 and a transmitting cable, MN2 and a receiving cable form a unit, and AB1 and MN1 are the head of the unit. The transmit and receive cables are at the end of the unit. Units can be connected in series, the measurement host is connected to the head of the unit through the transfer line 1, and connected to the tail of the unit through the transfer line 2. refer to figure 1 .

[0033] Each cable of each unit contains k taps (our actual product k is 4 or 10), ...

Abstract

The present invention relates to a high-density alternating current / direct current induced polarization system and a working method thereof, belonging to the field of geophysical instruments. The system comprises a measurement host, a multi-path electrode converter, a receiving cable, an emitting cable, a receiving electrode, an emitting electrode and a patch cord. The multi-path electrode converter comprises four interfaces. The receiving cable is completely separated from the emitting cable, and the receiving electrode is completely separated from the emitting electrode, the electromagneticcoupling problem of the emitting cable and the receiving cable and the problem of large signal drift of the receiving electrode are solved, it is avoided that a high-voltage emitting wire is too closeto a low-voltage receiving wire to cause high-voltage breakdown due to electric leakage of the emitting wire and cause damaging of an instrument; and moreover, compared to an unseparated cable, the high-density alternating current / direct current induced polarization system and the working method thereof can obviously improve the emitting current. The measurement system can effectively alternatingcurrent induced polarization measurement with high interference resisting and can perform conventional direct current induced polarization measurement so as to obviously improve the measurement efficiency and have an important practical value.

Description

technical field [0001] The invention belongs to the field of geophysical exploration instruments, and relates to a high-density AC / DC IP system and a working method thereof. Background technique [0002] The high-density induced polarization method is to arrange multiple electrodes at the same time, and combine them into a specified electrode device through the electrode conversion device, so as to realize the apparent resistivity and apparent polarizability of the multi-electrode distance at multiple measuring points on the observation section, video Divergence rate and apparent phase observation have the dual properties of resistivity profile method and resistivity sounding method. The high-density electrical method is characterized by a large number of measurement points and rich information. The induced polarization method is divided into AC induced polarization method (referred to as AC induced polarization) and DC induced polarization method (referred to as DC induced...
