The system comprises a computer, two multi-frequency intensification-polarization instrument receivers and a multi-frequency intensification-polarization instrument sender. Two sending ends of the multi-frequency intensification-polarization instrument sender and two receiving ends of the second multi-frequency intensification-polarization instrument receiver are respectively connected with grounding electrodes which are inserted into the earth. A sampling resistor is connected between one sending end of the multi-frequency intensification-polarization instrument sender and the grounding electrode connected with the sending end. Two ends of the first multi-frequency intensification-polarization instrument receiver are respectively connected with the two ends of the sample resistor in parallel. The two multi-frequency intensification-polarization instrument receivers are in a bidirectional connection with the computer.
Description
Technical field
The utility model relates to the device, particularly a kind of multifrequency induced polarization instrument system that suppresses phase drift and coupled noise that suppresses phase drift and coupled noise in a kind of electrical method geophysical prospecting equipment.
Background technology
At present, in the use of electrical method geophysical prospecting equipment receiver, because the variation of electric current in the current supply circuit is coupled to the electromagnetic wave of measuring the loop via the earth (or air) and is made the observation signal of induced polarization measurement produce distortion, this distortion can influence even fall into oblivion the sharp telecommunications breath of mineral matter; And, through facts have proved, in the use of multifrequency induced polarization instrument receiver, because the signal pickup electrode of measuring junction is inserted can produce some electricity in the soil environment, change effect, in signal is observed for a long time, these electricity, change effect can make phase parameter produce drift, thereby cause the erroneous judgement of underground mineral information disconnected.In more existing electrical method instruments, though taked some measures to suppress electromagnetic coupling effect, all can not obtain good effect, even can lose a part and swash the telecommunications breath; And, yet there is not a kind of effective solution for the inhibition problem of phase drift.
Summary of the invention
Technical problem to be solved in the utility model is, at the prior art deficiency, a kind of multifrequency induced polarization instrument system that suppresses phase drift and coupled noise is provided, do not losing under the prerequisite that swashs the telecommunications breath, suppress electromagnetic coupling effect well, and solve under the situation of long-term observation, phase place produces the problem of drift.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of multifrequency induced polarization instrument system that suppresses phase drift and coupled noise, comprise computing machine, two multifrequency induced polarization instrument receivers and a multifrequency induced polarization instrument transmitter, two transmitting terminals of described multifrequency induced polarization instrument transmitter and two receiving ends of the second multifrequency induced polarization instrument receiver respectively are connected to a ground-electrode that inserts the earth, be connected to a sample resistance between transmitting terminal of described multifrequency induced polarization instrument transmitter and the coupled ground-electrode, two receiving ends of the first multifrequency induced polarization instrument receiver are the described sample resistance two ends of inserting in parallel respectively; Described two multifrequency induced polarization instrument receivers all are connected with described computer bidirectional.
Compared with prior art, the beneficial effect that the utility model has is: the utility model can suppress electromagnetic coupling effect well not losing under the prerequisite that swashs the telecommunications breath, and solves under the situation of long-term observation, and phase place produces the problem of drift.

Embodiment
As shown in Figure 1, the utility model one embodiment comprises PC, two multifrequency induced polarization instrument receivers and a multifrequency induced polarization instrument transmitter, two transmitting terminals of described multifrequency induced polarization instrument transmitter and two receiving ends of multifrequency induced polarization instrument receiver 2 respectively are connected to a ground-electrode that inserts the earth, be connected to a sample resistance between transmitting terminal of described multifrequency induced polarization instrument transmitter and the coupled ground-electrode, two receiving ends of multifrequency induced polarization instrument receiver 1 are the described sample resistance two ends of inserting in parallel respectively; Described two multifrequency induced polarization instrument receivers all are connected with described PC is two-way.
The ground-electrode of setting multifrequency induced polarization instrument transmitter transmitting terminal is A, B, and the ground-electrode of two receivers (receiver 1 and receiver 2) receiving end is M, N.Because electromagnetic coupling effect is that the variation of electric current causes in the current supply circuit, during construction, powerful sample resistance of the A utmost point (the perhaps B utmost point) series connection before the direct current that multifrequency induced polarization instrument transmitter transmitting terminal sends feeds the earth, the two ends of sample resistance are inserted respectively between the M utmost point and the N utmost point of receiver 1, and made receiver 1 operate as normal; Simultaneously, at receiving end, two ground-electrodes are inserted the earth, and with lead the M utmost point and the N utmost point of receiver 2 are inserted in the two ends of electrode, and make receiver 2 operate as normal.Like this, receiver 1 has been preserved the measurement parameter that comprises coupled noise and phase drift, and receiver 2 has been preserved and comprised coupled noise, phase drift, and the measurement parameter of sharp telecommunications breath.After construction is finished, with the measurement parameter importing PC of receiver 1 and receiver 2 preservations, and by the corresponding sharp telecommunications breath parameter of subtracting each other after namely being inhibited of time relation.
