Description
Technical field
The present invention relates to a kind of heat treatment method, this method may be used for detection, draws and assesses the underground mine with spectrum magnetic activity.
Background technology
According to prior art, heat treatment method does not use the transmission source of self ACTIVE CONTROL, but constantly utilize and passively accept magnetic field, magnetic field constantly changes (Simpson in time, F. & Bahr, K.:PracticalMagnetotellurics, S.182, CambridgeUniversityPress, 2005).In conventional method, the outside inductive action of ionosphere and magnetosphere forms magnetic field.In addition, according to current method, horizontal conductivity gradient can be calculated, and the underground mine with spectrum magnetic activity can not be detected.
Summary of the invention
Task of the present invention is the method createing heat treatment mentioned above, and utilize the method can determine the orientation, particularly oil gas of the underground mine with spectrum magnetic activity and the orientation of rich ore, this depends primarily on the geogen in formation location, underground.
According to the present invention, feature according to claim 1 is by this object of solution.
Dependent claims will describe favourable embodiment.
Utilize this for detection, draw and assess the magnetic changing method with the underground mine of spectrum magnetic activity, signal intensity and/or the field variable in the unusual magnetic field of constantly change in time existed in survey region or in the rock mass on earth's surface can be measured, should measure by place and time at least one direction in space, by data processing (especially spectral analysis), the measurement data of the temporally sequence measuring that each measuring position obtains is converted to the spectral power that frequency range is 0.01 to 100Hz, at least one spectral properties (especially its power) is determined thus, by the attribute variable's value after unitizing based on reference value and standard reference value are compared, thus distinguish underground there are mineral reserve in the rock mass of spectrum magnetic activity and non-mineral reserve.
Such as, oil and gas deposit (oil, rock gas) or ore mineral reserve are the underground mines with spectrum magnetic activity.At present, this method can be utilized to detect unusual spectrum magnetic activity performance with non-oil and gas deposit and non-ore mineral reserve rock mass, and draw out corresponding underground mine according to these performance identifications.Such as, exploration context is very large and/or when being difficult to enter, and economically, measurement is significant, then helicopter can be used to carry out the measurement of the above exploration context in earth's surface.Data in the present invention more than the earth's surface of indication or earth's surface are water surface, and as lake or ocean, the measurement namely in exploration context both at water surface, also can be carried out above top or its.
The method may be used for detecting the rock mass and subterranean layer that are 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 to store situation and using its relative yield-power as extra criterion.On the basis of these results, when detecting, huge economic interests can be realized, because purposively deep drilling can be carried out, avoid mistake boring.In addition, based on control measurement, the exploitation of oil and gas deposit can be optimized.
Ore mineral reserve within the scope of all right detecting rock of this method, draw its distribution range, obtain the amount analysis of potential ore intensity.
Its advantage is directly to determine underground ore storage situation and using its relative intensity as extra criterion.On the basis of these results, when exploring, huge economic interests can be realized, because purposively exploratory boring can be carried out, avoid mistake boring.In addition, exploitation measure can be planned, as mining equipment.
In embodiment, at least synchronously carrying out magnetic activity measurement two measuring positions, can be left and right or neighbouring two positions.Such as, the helicopter vertical direction that identical surveying instrument equipped by two framves is flown mutually towards the other side direction and measures, especially when mutual spacing is from being approximately 10m to 500m, preferred distance is 100m to 350m.By gradiometry, can determine to be rich in the rock mass of oil and gas deposit and the depth profile of subterranean layer.Also can different spaces orientation measurement instrument be used to carry out synchro measure a measuring position.
As everyone knows, magnetometer can be used to measure irregular electromagnetism magnetic field.Also can, by two electrode ground connection and the voltage difference measured between them, electronics magnetic field sensor be used to measure the electromagnet portion of constantly variation magnetic field in time.
Should understand like this, mentioned above and hereinafter the technical characteristic of elaboration not only can be applied to each combination of specifying, also can be applied to other combination.Scope of the present invention is only limited by claim.
Accompanying drawing explanation
Hereafter will set forth the present invention further by embodiment and relevant indicators.
Fig. 1 is the figure that sectional view and carrying out according to the method for the invention is measured,
Fig. 2 be the figure that draws according to two frequency spectrum and
Fig. 3 is the profile diagram according to underground petroleum edge extent arbitrary shape.
Embodiment
Fig. 1, according to the time, uses conventional magnetometer 3 and data acquisition unit 4, and the magnetic field (being indicated by arrow 2) of the constantly change in time that underground oil and gas mineral reserve 1 discharge is measured as voltage signal on each receiving station (measuring position) earth's surface 8.On the basis of spectral analysis calculating method, computer supported data processor 5, obtains measurement data in each measuring position according to the time thus, can obtain spectral power, and frequency range is 0.01 to 100Hz(Fig. 2).At least can calculate the sizes values of a spectral properties 6, especially its performance.
Two kinds of exemplary power frequency spectrum that heat treatment is measured are depicted in Fig. 2.9 curves drawn indicate the measurement result without oil and gas deposit receiving station by a dotted line, and the curve that solid line 10 is drawn represents underground oil and gas mineral reserve content.Within the scope of certain frequency, draw oil and gas deposit curve by the magnitude of power increased considerably, exceed the numerical value that the unified display of non-oil and gas deposit curve of whole frequency range is lower.
Fig. 3, what profile diagram showed is the exploration context comprising the distribution of standard spectrum attribute level line, determines these attributes according to heat treatment measurement.Reference measure is carried out outside exploration context, namely the measuring position in the vertical range of known oil and gas deposit lateral edge is measured, attribute reference point 7(Fig. 1 can be obtained), this value is as the respective attributes sizes values 6 being used for obtaining in specification exploration context with reference to value.Calculate reference point level line 11 change in location that can draw standard from the distribution of unified attribute size value, this line represents the curve of the kind attributes value equal with reference value 7.When standard attribute value is greater than 1, show there is oil and gas deposit in exploration context, accordingly, if when this value is less than 1, then within the scope of this without oil and gas deposit.In addition, standard attribute value basis can draw the matter numerical value of oil and gas deposit yield-power, and these numerical value divide according to grade.
