Description

Technical Field

[0001] The invention relates to the technical field of salt lake lithium resource mining, in particular to a salt lake stratum-position holographic flow field analysis technology based on biological tracing. Background Art

[0002] At present, with the rapid growth of the new energy and energy storage equipment markets, the demand for lithium resources is also increasing, and the demand for lithium resource mining will continue to increase. The development and utilization of salt lake lithium resources has become one of the indispensable and important industries in today's society. However, due to the complex geological formations of salt lakes, the uneven distribution of groundwater flow fields and brine formations in salt lakes, traditional exploration is difficult to accurately determine the specific flow direction of brine in the formation, and can no longer meet the needs of salt lake lithium resource mining. In addition, the effective extraction range of current extraction wells is often unclear, resulting in low resource utilization efficiency. This further increases the difficulty and uncertainty of resource extraction.

[0003] Therefore, in order to ensure the working efficiency of each extraction well, accurately describe the hydrogeological characteristics of the production layer around the extraction well, clarify the information such as the thickness of the mining area in different regions, resource quality, seepage resistance, and the actual extraction area of ​​the extraction well, a salt lake fixed-layer holographic flow field analysis technology based on biological tracers is urgently needed to realize accurate flow field analysis and law research in the mining area. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: This technology realizes the accurate detection and analysis of the effective extraction range of the extraction well, and provides technical guarantee for improving the mining efficiency and scientific management level of salt lake lithium ore resources.

[0005] To achieve the purpose of the present invention, the present invention is implemented through the following technical scheme: based on the vertical geological zoning of the salt lake and centered on the brine extraction well, a full-elevation three-dimensional sparse matrix exploration point system of the target aquifer is designed, and the tracer bacteria injection points and observation points are classified; the drilling layer is actively determined by the detection while drilling technology, and each exploration point is accurately positioned and controlled; the working status of the brine extraction well is determined by grouping and zoning the regional flow field characteristics with the biological tracer technology, and the data is integrated to realize the holographic basin characteristic analysis of the mining area, draw the spatial distribution of the mainstream field, clarify the flow pattern law, clarify the core range of the mining area, and realize the holographic flow field analysis of the salt lake at a fixed layer.

[0006] The present invention discloses a holographic flow field analysis technology for salt lake strata based on biological tracers, which comprises the following steps: taking the vertical geological strata of the salt lake as the basis, taking the brine extraction well as the center, designing a full-elevation three-dimensional sparse matrix exploration point system for the target aquifer, and classifying the injection points and observation points of tracer bacteria; actively determining the drilling strata by using the detection while drilling technology, and implementing precise positioning and control for each exploration point; determining the working status of the brine extraction well, determining regional flow field characteristics by grouping and zoning with the biological tracer technology, integrating data to realize holographic flow basin characteristic analysis of the mining area, drawing the spatial distribution of the mainstream field, clarifying the flow pattern law, clarifying the core range of the mining area, and realizing holographic flow field analysis for salt lake strata.

[0007] As a preferred technical solution of the present invention, the full-elevation three-dimensional sparse matrix detection point system is a spatial layout method of detection points for three-dimensional segmentation of the target area. The full-elevation three-dimensional sparse matrix detection point system takes the extraction well as the central axis and the boundary point of the aquiclude on the axis as the base point of the coordinate system. According to the topography, geological structure and trend distribution of the target brine layer, the direction and density of the grid lines are planned, and the first injection point (1) of the tracer bacteria and two edge injection points (2-1, 2-2) are planned in the vertex area of ​​the grid lines, and the first injection point (1) and the edge injection point (2) form a local spatial network relationship; except for the tracer bacteria injection point, all other points in the full-elevation three-dimensional sparse matrix detection point system are detection points of the same level.

[0008] As a preferred technical solution of the present invention, the drilling detection technology is an active cross-stratum determination technology that is achieved by accurately detecting the aquiclude, and completes active identification of the aquiclude and seepage analysis respectively. Before drilling, the geological structure of each aquiclude above the target layer is determined, the type and original properties of water-blocking clay are clarified, and a method for rapid separation of clay and other associated mineral sources by the swelling liquid method and determination of their content is established; during the drilling process, the maximum drainage capacity of each point is first determined by the suction method to infer the seepage, and the endpoint flow rate and flow direction are simultaneously determined; at the same time, ultra-fine bubbles are used to construct swelling liquid, and large particles of associated minerals are quickly precipitated in the sampling liquid, and the clay content is evaluated by the turbidity method. According to the sudden change in clay content, it is determined whether the current drilling position enters and exits the aquiclude, thereby realizing active cross-stratum determination of salt lake geology.

[0009] As a preferred technical solution of the present invention, the point-to-point flow rate determination needs to be completed before the implementation of the biological tracer technology. Based on the seepage volume, endpoint flow rate and flow direction data of each point obtained in the implementation of the drilling detection technology, the flow time of each path is calculated from each first injection point (1) and edge injection point (2) as the starting point and the brine extraction well as the end point. On this basis, it is necessary to select tracer bacteria that meet the following conditions: (a) have good salt tolerance to the target layer brine; (b) can maintain good bioluminescence characteristics within 1.5 times the time required for the maximum flow field; (c) the bioluminescence characteristics disappear due to the destruction of salinity within 1.5-2 times the time required for the maximum flow field.

[0010] As a preferred technical solution of the present invention, the method of determining regional flow field characteristics by grouping and zoning with biological tracer technology is based on a full-elevation three-dimensional sparse matrix probe point system, with the tracer bacteria injection point as the starting point and the brine extraction well as the end point, and injections are made in the order of the first injection point (1), the edge injection point 1# (2-1), and the edge injection point 2# (2-2). During the technical implementation of each tracer bacteria injection point, all probe points will determine the arrival time and abundance changes of the tracer bacteria according to the estimated arrival order. After the implementation of the first injection point (1), the edge injection points (2-1, 2-2) are used for technical implementation respectively, and the matrix data of the edge injection points (2-1, 2-2) are compared with the data of the first injection point (1). If the deviation is higher than 10%, two new candidate edge injection points are added to the group to enrich the flow field data of the control area of ​​the group, clarify the source of data differences, and verify the accuracy of the monitoring data of each point.

[0011] As a preferred technical solution of the present invention, the full-elevation three-dimensional sparse matrix exploration point system is specifically arranged as follows:

[0012] Positioning and arrangement of the tracer bacteria injection point: the drill bit will drill down 2m when it reaches the critical exit aquiclude (5). If it enters the critical entry aquiclude (6) before reaching 2m, the drill bit will be recovered to half the depth, and the coordinates of the actual injection point from the overlying aquiclude will be recorded;

[0013] The tracer bacteria detection point is positioned and arranged; the mining layer thickness is evaluated based on the geological exploration data, and the sampling drill rod length is determined. During the drilling operation, when the critical water-proof layer (5) is reached, the exploration depth is recorded until the depth of 0.5 meters of the bottom plate water-proof layer is reached. The actual sampling drill rod length arranged at the point is recorded, and the three-dimensional coordinate position of the sampling point is calculated and recorded.

[0014] As a preferred technical solution of the present invention, the holographic watershed characteristic analysis of the mining area is completed and the test data of all points are matched with the full-elevation three-dimensional sparse matrix exploration point system to compare and analyze the regional flow field distribution and flow state characteristics when the brine extraction well is in working condition. The regional flow field distribution is different from the extraction flow field distribution under classical ideal geological conditions. According to the difference in seepage resistance in different regions and points, the regional flow field with non-spherical surface distribution will be depicted, thereby clarifying the flow pattern law, clarifying the core range of the mining area, and realizing the real mainstream field spatial distribution drawing; at the same time, the patented technology can realize the determination of advection and turbulence: if the sampling drill rod at each position in a group of tracer areas only detects tracer bacteria at a specific point, the flow field in this area is determined to be stratospheric; if the sampling drill rod at each position in a group of tracer areas first detects tracer bacteria at one point, and the adjacent upper and lower points detect them successively, and show typical hysteresis, the flow field in this area is determined to be approximately stratospheric; if the receiving sequence shows significant non-sequential changes, that is, it does not conform to the natural flow law, then this situation indicates that the fluid may be in a turbulent state or there is a transition zone between laminar flow and turbulent flow locally. Based on the comprehensive analysis of the flow path, state, direction and velocity of the tracer medium, the analysis of the holographic flow basin characteristics of the mining area is realized.

[0015] The beneficial effects of the present invention are:

[0016] 1. Accurately locate the effective extraction range of the extraction well: By combining biological tracer technology with the full-elevation three-dimensional sparse matrix detection point system, it is possible to accurately detect and analyze the flow direction and flow field characteristics of brine in the salt lake formation, clarify the effective extraction range of the extraction well, and thus improve resource utilization efficiency.

[0017] 2. Clarify the flow field distribution and flow pattern laws: The present invention can analyze in detail the influence of seepage resistance in different areas on the flow field distribution, draw a real mainstream field spatial distribution map, help clarify the flow pattern laws, and provide a reliable basis for scientific development and management.

[0018] 3. Improve mining efficiency and scientific management level: Through the application of drilling detection technology, active determination of drilling layers and precise positioning and control can be achieved. Combined with the grouping and zoning determination of biological tracer technology, the working status of the extraction wells can be monitored in real time, the mining strategy can be optimized, and the mining efficiency and scientific management level of salt lake lithium ore resources can be significantly improved.

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Embodiment 1:

[0026] The following is a specific implementation of the salt lake stratum positioning holographic flow field analysis technology based on biological tracers of the present invention, which is described in detail as follows:

[0027] Step (1) Design of full-elevation three-dimensional sparse matrix exploration point system:

[0028] Selection of coordinate system base point: The full-elevation three-dimensional sparse matrix exploration point system takes the extraction well as the central axis and the boundary point of the impermeable layer above the axis as the coordinate system base point.

[0029] Coordinate system grid design: According to the topography, geological structure and trend distribution of the target brine layer, the XY axis direction and density of the grid lines are planned (the XY grid line density is 10 meters in this embodiment). The maximum brine layer height based on geological exploration and assessment is the maximum value of the Y axis, and the grid line density is 1 meter.

[0030] Tracer bacteria injection point and detection point arrangement: Plan a first injection point (1) and two edge injection points (2-1, 2-2) in the grid line vertex area to form a triangular distribution of vertex groups. The first injection point and the edge injection point form a local spatial network relationship. In the full-elevation three-dimensional sparse matrix detection point system, except for the first tracer bacteria injection point (1), all other points are detection points of the same level.

[0031] Step (2) Using detection while drilling technology to determine the layer position:

[0032] Before the implementation of the technology: Use the core of the extraction well to analyze the geological structure, clay content and properties of the aquiclude. Take 100g of core from each typical section of the aquiclude, dry and hammer grind it through a 20-mesh sieve, and analyze the hardness and crushing difficulty of the clay and associated minerals. Mix it with water at a ratio of 1:20, stir it thoroughly to form a suspension, adjust the ultrafine bubble intake, control the liquid expansion rate, select the best ultrafine bubble arrangement parameters for clay suspension within 10 seconds but other associated minerals to complete sedimentation, and measure the turbidity of the suspension at the same time to determine the identification method of the drill bit entering and exiting the clay layer.

[0033] During the actual drilling process: each time a measurement position is reached, a high-speed underground drilling method is used to break the rock layer by the cutting action of the drill bit to facilitate the measurement of the swelling liquid clay content. After the swelling liquid clay content is measured, the drilling pump stops working, and after waiting for 10 minutes, the flow rate and flow direction are determined by the rotary head flow field sensor, and then the drilling pump gradually increases the suction volume until the suction resistance increases by 20% or the supply volume at the drilling position is insufficient to support the pump displacement, which is determined as the maximum seepage flow at the point.

[0034] Step (3) Determination of the maximum point-to-point flow duration: Based on the velocity and direction data of each point endpoint obtained during the implementation of the detection while drilling technology, the evaluation starts from the first injection point (1) and the edge injection point (2-1, 2-2) of each vertex group and ends at the brine extraction well. Based on the initial state of the fluid at these starting points, including flow velocity and flow direction, the classical model is used to calculate the flow duration of the tracer bacteria on each path. After comparative analysis, the required duration of the maximum flow field is obtained as the basis for determining the effective fluorescence period of the tracer bacteria.

[0035] Step (4) Screening of tracer bacteria: Screen fluorescent tracer bacteria from a strain library known to be salt-tolerant. The target strain must meet the following conditions:

[0036] It has good salt tolerance to the target layer brine;

[0037] It can maintain good bioluminescence characteristics within 1.5 times the time required for the maximum flow field;

[0038] The bioluminescence characteristics disappear due to the destruction of salinity within 1.5-2 times the time required for the maximum flow field.

[0039] Step (5) The biological tracer technology is used to divide the flow field characteristics into groups: based on the full-elevation three-dimensional sparse matrix probe point system, with the tracer bacteria injection point as the starting point and the brine extraction well as the end point, the injection is carried out in the order of the first injection point (1), the edge injection point 1# (2-1), and the edge injection point 2# (2-2). During the technical implementation of each tracer bacteria injection point, all probe points will determine the arrival time and abundance changes of the tracer bacteria according to the estimated arrival order. After the implementation of the first injection point (1), the edge injection points (2-1, 2-2) will be used for technical implementation, and the matrix data of the edge injection points (2-1, 2-2) will be compared with the data of the first injection point (1). If the deviation is higher than 10%, the group will add two new alternative edge injection points to enrich the flow field data of the control area of ​​the group, clarify the source of data differences, and review the accuracy of the monitoring data at each point.

[0040] Positioning and arrangement of the tracer bacteria injection point: the drill bit will drill down 2 meters when it reaches the critical exit aquiclude (5). If it enters the critical entry aquiclude (6) before reaching 2 meters, the drill bit will be recovered to half the depth, and the coordinates of the actual injection point from the overlying aquiclude will be recorded;

[0041] Positioning and arranging of tracer bacteria detection points: The thickness of the mining layer is evaluated based on the geological exploration data, and the length of the sampling drill rod is determined. During the drilling operation, the drill bit starts to record the depth of the exploration when it is critical to the impermeable layer (5), and continues until it enters the bottom plate impermeable layer at a depth of 0.5 meters. The actual length of the sampling drill rod arranged at the point is recorded, and the three-dimensional coordinate position of the sampling point is calculated and recorded.

[0042] Step (6) Holographic flow basin characteristics analysis of the mining area: After the test is completed, all point test data are matched with the full-elevation three-dimensional sparse matrix detection point system, and the full-elevation three-dimensional sparse matrix detection point system is corrected to compare and analyze the regional flow field distribution and flow state characteristics when the brine extraction well is in working state. In this way, the flow state law is clarified and the core range of the mining area is clarified. At the same time, the advection and turbulence are determined: if the sampling drill rod at each position in a group of tracer areas only detects tracer bacteria at a specific point, the flow field in this area is determined to be stratospheric; if the sampling drill rod at each position in a group of tracer areas first detects tracer bacteria at one point, and the adjacent upper and lower points detect them successively, and show typical hysteresis, the flow field in this area is determined to be approximately stratospheric; if the receiving sequence shows significant non-sequential changes, that is, it does not conform to the natural flow law, then this situation indicates that the fluid may be in a turbulent state or there is a transition zone between laminar flow and turbulent flow locally. Combined with the comprehensive analysis of the flow path, state, direction and speed of the tracer medium, the analysis of the holographic flow basin characteristics of the mining area is realized.

[0043] Step (7) Drawing of a holographic flow field distribution map of a salt lake at a fixed layer: Based on the data obtained by the bio-tracer technology, such as the flow path, state, direction and speed of the tracer medium, Python is combined with the mplot3d toolkit of matplotlib to draw a 3D map of the holographic flow field distribution map of a salt lake at a fixed layer.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
