Description
Technical Field
The application relates to the technical field of resource exploration, in particular to a method and a device for determining a uranium ore stratum position.
Background
The sandstone-type uranium ore plays an important role in the global resource structure and is one of the four traditional industrial uranium ores in China. The mineralization of sandstone-type uranium ores usually needs to undergo long geological evolution, and the mineralization process is often restricted by various mineralization conditions, such as tectonic conditions, paleoclimatic conditions, lithofacies paleogeographic conditions, lithological conditions, hydrological geochemical conditions, uranium source conditions and the like. Under the constraint of the ore forming conditions, the ore forming process of the sandstone-type uranium ore becomes more complex, and the prediction of the stratum position of the sandstone-type uranium ore is not facilitated.
At present, the method for determining the stratum position of sandstone-type uranium ores is mainly a radioactive exploration method. The method mainly comprises the following steps: arranging a plurality of measuring points on the ground surface of a target work area, such as the ground surface of a hydrocarbon-containing basin, according to a certain distance, and measuring the intensity of gamma rays emitted by stratum rocks at different stratum depths at the position of one measuring point along the direction vertical to the ground surface; if sandstone-type uranium ores exist at a certain stratum depth position of a certain measuring point position, the measured gamma ray intensity at the stratum depth position is usually abnormal; for example, the measured gamma-rays may typically have an intensity that is more than 2 times the intensity of gamma-rays at formation depths where sandstone-type uranium ores are not present. In this way, according to the intensity of the gamma rays emitted by the formation rock at different depths measured at the measuring point, whether the sandstone-type uranium ore exists at the different depths of the measuring point can be judged, so that the formation position of the sandstone-type uranium ore in the target work area can be predicted.
The inventor finds that at least the following problems exist in the prior art: for a target work area with a complex structure, for example, a target work area with a thick stratum of an overlying stratum of a sandstone-type uranium mine, it may be difficult to measure the gamma ray intensity of a measurement point position in the work area, which is abnormal at the depth of the stratum containing the sandstone-type uranium mine, and then it may be impossible to determine whether the sandstone-type uranium mine exists in the stratum at the measurement point position. Therefore, the specific stratum position of the sandstone-type uranium ore in the complex target work area can be difficult to accurately determine by the existing method for determining the stratum position of the uranium ore.

Detailed Description
The embodiment of the application provides a method and a device for determining a uranium ore stratum position.
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
FIG. 1 is a flow chart of an embodiment of a method of determining a location of a uranium mine formation according to the present application. As shown in fig. 1, the method for determining the position of a uranium ore formation includes the following steps.
Step S101: acquiring exploration information of a target work area, and determining a three-dimensional initial region of the sandstone-type uranium deposit in the target work area according to the exploration information.
The target work area can be a basin containing oil gas. The destination work area may include: at least one earth formation. For example, sandstone-type uranium ores may be located in sandstone formations.
The survey information may include: geophysical information, well logging information and hydrological information. In particular, the geophysical information may generally include: and the stratum fluctuation distribution, the stratum structure trend, the stratum lithology and the like in the target work area. The logging information may generally include: and the resistivity logging curve, the natural potential logging curve, the lithology logging curve, the density logging curve and the like at the drilling position in the target work area. The hydrologic information may generally include: the water content, the surface water level, the water flow, the precipitation and the like in the target work area.
The geophysical prospecting information of the target work area can be acquired by a geophysical prospecting method, i.e., a geophysical prospecting method, such as gravity prospecting, magnetic prospecting, electrical prospecting, seismic prospecting, and the like. Geological exploration can be carried out in a drilling mode, and the logging information of the target work area is obtained. The hydrological information of the target work area can be obtained in a field survey recording mode.
In the target work area, the area where the sandstone-type uranium ore exists generally has the following ore-forming characteristics: (1) the stratum structure trend of the area is a slope, and the stratum lithology is sandstone; (2) the region is hydrated; (3) the lithology log and the density log of the peripheral stratum rock in the region are characterized as granite rock. According to the stratum structure trend and the stratum lithology in the geophysical prospecting information, the region which is in accordance with the mineralization characteristics (1) in the target work area can be determined. According to the water content in the hydrological information, the area which is in accordance with the mineralization characteristics (2) in the target work area can be determined. And determining the region which accords with the mineralization characteristics (3) in the target work area according to the lithological well logging curve and the density well logging curve in the well logging information. In this way, according to the exploration information, the region in the target work area which meets the mineralization characteristics (1), (2) and (3) can be used as a three-dimensional initial region of the sandstone-type uranium ore in the target work area. The three-dimensional region may include a inline dimension, a crossline dimension, and a formation depth dimension. The three dimensions are orthogonal two by two. The formation depth of the three-dimensional initial zone may range from the surface to a formation depth of 1000 meters below the surface.
Step S102: and arranging a plurality of measuring points on the surface of the three-dimensional initial region, and determining the free hydrocarbon content and the natural potential difference at the position of a first measuring point of the three-dimensional initial region and the induced phase shift at the first formation depth of the position of the first measuring point.
A plurality of measuring points can be arranged on the ground surface of the three-dimensional initial area. Specifically, a plurality of measuring points may be arranged on the ground surface of the three-dimensional initial region at preset intervals. The preset interval may be 100 meters. For example, a plurality of measuring lines can be respectively arranged on the ground surface of the three-dimensional initial region along the main measuring line dimension and the contact measuring line dimension, the distance between every two measuring lines is 100 meters, a plurality of measuring points can be arranged on each measuring line, and the distance between every two measuring points can be 100 meters.
The free hydrocarbon content at the location of the first station can be determined. Wherein the free hydrocarbon may be methane. Specifically, a soil pumping sample at a first measuring point position of the three-dimensional initial region can be obtained. For example, the sampling can be performed by drilling, and the drilling depth can be 1-2 meters. The soil extracted gas sample can be subjected to chemical analysis treatment by adopting a free hydrocarbon geochemistry detection method, so that the free hydrocarbon content of the soil extracted gas sample is obtained. The first measuring point may be any one of a plurality of measuring points of the three-dimensional initial region. The free hydrocarbon content of the soil pump sample can be taken as the free hydrocarbon content at the location of the first station. In this way, the free hydrocarbon content at each station position of the three-dimensional initial region can be determined.
The natural potential difference at the location of the first measuring point can be determined. Specifically, natural potential measurement may be performed on a preset base point position and the first measurement point position by a natural potential measurement method, so that a natural potential at the preset base point position and a natural potential at the first measurement point position may be obtained respectively. The preset base point position may be a preset position on the ground surface of the three-dimensional initial region. And subtracting the natural potential at the position of the first measuring point from the natural potential at the position of the preset base point to calculate the natural potential difference at the position of the first measuring point.
When sandstone-type uranium ores exist at a stratum depth of a measuring point position of the three-dimensional initial region, an excitation point corresponding to the measuring point position sends an excitation current to the underground, and the excitation phase at the stratum depth may lag behind the excitation phase of the excitation current due to the polarization effect of the sandstone-type uranium ores at the stratum depth, that is, the excitation phase at the stratum depth may have a certain excitation phase shift.
The induced phase shift at the first station location can be determined. Specifically, an excitation current may be sent to the ground at an excitation point corresponding to the first measurement point position according to a preset frequency, and an electric field signal corresponding to the excitation current may be received at a receiving point corresponding to the first measurement point position. The distance between the excitation point and the measuring point can be 10-50 meters. The distance between the receiving point and the measuring point can be 10-50 meters. The received electric field signal can be processed by adopting a phase induced signal processing method to obtain the induced phase shift at the first formation depth of the first measuring point position. The first measuring point positions have different induced phase shifts at different stratum depths. The first formation depth may be any formation depth of the first survey point location. The induced phase shift at the first formation depth of the first survey point location may comprise: and the surface of the first measuring point is shifted by the exciting phase. And the induced phase shift of the earth surface at the position of the first measuring point is the induced phase shift of the zero depth of the stratum at the position of the first measuring point.
Step S103: and determining a three-dimensional target region of the sandstone-type uranium ore in the target work area from the three-dimensional initial region based on the free hydrocarbon content and the natural potential difference at the first measuring point position and the induced phase shift at the first formation depth of the first measuring point position.
Specifically, based on the free hydrocarbon content and the natural potential difference at the first measuring point position and the induced phase shift at the surface of the earth at the first measuring point position, a target plane region of the sandstone-type uranium deposit in the target work area can be determined from the surface plane region of the three-dimensional initial region. The surface plane region may be a plane region of the three-dimensional initial region on the surface of the earth. The target planar area may be a planar area of the three-dimensional target area on the surface of the earth. Based on the induced phase shift at the first formation depth for the first survey point location, a target formation depth zone for the first survey point location may be determined. And determining a three-dimensional target area of the sandstone-type uranium deposit in the target work area based on the target plane area and the target stratum depth area.
And determining a target plane area of the sandstone-type uranium ore in the target work area from the surface plane area of the three-dimensional initial area based on the free hydrocarbon content and the natural potential difference at the first measuring point position and the induced phase shift at the surface of the first measuring point position. Specifically, a region constituted by first measuring point positions satisfying the following conditions may be taken as the target plane region: the content of free hydrocarbon at the position of the first measuring point is greater than a preset free hydrocarbon content threshold value, the natural potential difference at the position of the first measuring point is greater than a preset natural potential difference threshold value, and the induced phase shift at the surface of the first measuring point is greater than a first preset induced phase shift threshold value. The value range of the preset free hydrocarbon content threshold value can be 3-4 times of the average value of the free hydrocarbon content at all measuring point positions of the three-dimensional initial region. The value range of the preset natural potential difference threshold value can be 3-4 times of the average value of the natural potential differences at all the measuring point positions of the three-dimensional initial area. The value range of the first preset excitation phase shift threshold value can be 3-4 times of the average value of the excitation phase shifts at the earth surface of all measuring point positions of the three-dimensional initial region.
And determining a target stratum depth region of the first measuring point position based on the excitation phase shift at the first stratum depth of the first measuring point position. Specifically, a region made up of a first formation depth satisfying the following conditions may be taken as the target depth region: and the excitation phase shift at the first formation depth of the first measuring point position is greater than a second preset excitation phase shift threshold value. The value range of the second preset excitation phase shift threshold value can be 3-4 times of the average value of the excitation phase shifts at the first formation depth of all the measuring point positions of the three-dimensional initial region.
And determining a three-dimensional target area of the sandstone-type uranium deposit in the target work area based on the target plane area and the target stratum depth area. Specifically, a three-dimensional region formed by the target plane region and the target formation depth region may be used as the three-dimensional target region of the sandstone-type uranium deposit in the target work area.
According to the embodiment of the method for determining the uranium mine stratum position, a plurality of measuring points are arranged on the surface of the three-dimensional initial region, so that the content of free hydrocarbon and the natural potential difference at the first measuring point position of the three-dimensional initial region and the induced phase shift at the first stratum depth position of the first measuring point position are obtained; and determining a three-dimensional target region of the sandstone-type uranium ore in the target work area from the three-dimensional initial region according to the free hydrocarbon content and the natural potential difference at the position of the first measuring point and the induced phase shift at the first formation depth of the position of the first measuring point. The content of free hydrocarbon, the natural potential difference and the induced phase shift obtained in the method can reflect the ore forming conditions of the sandstone-type uranium ore, and are not influenced by the stratum thickness of an overlying stratum of the sandstone-type uranium ore in a target work area, so that the accuracy of the determined stratum position of the sandstone-type uranium ore can be improved.
Fig. 2 is a block diagram of an embodiment of an apparatus for determining a position of a uranium mine formation according to the present application. As shown in fig. 2, the apparatus for determining a position of a uranium ore formation may include: an initial region determination module 100, a station position information determination module 200 and a target region determination module 300.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip 2. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most popular applications. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory.
Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions.

Memory is an example of a computer-readable medium. Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device.
