By means of this magnetic variation method for detecting, mapping and evaluating underground mineral deposits with spectral magnetic activity, the signal intensity and/or field variables of the anomalous magnetic field that changes over time in the rock mass in the study area or on the surface can be measured. The measurements should be carried out in at least one spatial direction according to location and time. By data processing (especially spectral analysis), the measurement data obtained in time series at each measurement position are converted into spectral power with a bandwidth of 0.01 to 100 Hz, thereby at least one spectral attribute (especially its power) is determined. By comparing the attribute variable value unified based on the reference value with the standard reference value, mineral deposits and non-mineral deposits in the underground rock mass with spectral magnetic activity can be distinguished.
Description
The present invention relates to a kind of heat treatment method, this method can be used for surveying, and draws and assess the underground mine with spectrum magnetic activity.
According to prior art, the heat treatment method is not used the transmission source of self ACTIVE CONTROL, but constantly utilizes passive receive magnetic field, and magnetic field constantly changes (Simpson, F. ﹠amp in time; Bahr, K.: Practical Magnetotellurics, S. 182, Cambridge University Press, 2005).In conventional method, the outside inductive action of ionosphere and magnetosphere forms magnetic field.In addition, the method according to present can calculate the horizontal conductivity gradient, and can not detect the underground mine with spectrum magnetic activity.
Task of the present invention is to create the method for heat treatment mentioned above, utilizes the method can determine to have the orientation, particularly oil gas of underground mine of spectrum magnetic activity and the orientation of rich ore, and this depends primarily on the geogen in underground formation location.
According to the present invention, feature claimed in claim 1 will solve this purpose.
Dependent claims will be described favourable embodiment.
utilize this for detection, draw and assess the magnetic variation method of the underground mine with spectrum magnetic activity, signal intensity and/or the field variable in the unusual magnetic field that constantly changes in time that can measure in survey region or exist in the rock mass on earth's surface, should measure by place and time at least one direction in space, process (especially spectral analysis) by data, it is 0.01 to 100Hz spectral power that the measurement data by the time sequence measuring that obtains on each measuring position is converted to frequency range, at least one spectral properties (especially its power) is determined thus, compare by attribute variable's value and canonical reference value after unitizing based on reference value, thereby distinguish mineral reserve and non-mineral reserve in underground rock mass with spectrum magnetic activity.
For example, oil and gas deposit (oil, rock gas) or ore mineral reserve are the underground mines with spectrum magnetic activity.At present, can utilize this method to detect unusual spectrum magnetic activity performance with non-oil and gas deposit and non-ore mineral reserve rock mass, and identify and draw out corresponding underground mine according to these performances.For example, exploration context is very large and/or when being difficult to enter, and economically, measurement is significant, can use helicopter to carry out the measurement of the above exploration context in earth's surface.In the present invention, the above data in the earth's surface of indication or earth's surface are the surface, waters, and as lake or ocean, i.e. measurement in exploration context both can be on the surface, waters, also can carry out above top or its.
The method can be used for surveying rock mass and the subterranean layer that is rich in oil and gas deposit, draws its distribution range, obtains the amount analysis of potential hydrocarbon mineral reserve yield-power and carries out time monitoring at mining phase.
Its advantage is directly to descend definitely oil and natural gas storage situation and yield-power that it is relative as extra criterion.On the basis of these results, can realize huge economic interests when surveying, because can purposively carry out deep drilling, avoid wrong boring.In addition, based on control measurement, can optimize the exploitation of oil and gas deposit.
Ore mineral reserve in all right detecting rock scope of this method are drawn its distribution range, obtain the amount analysis of potential ore intensity.
