Description

Technical Field

[0001] This invention relates to the field of ecological monitoring technology for oil and gas fields in desert areas, specifically a method for verifying remote sensing monitoring results of oil and gas fields in desert areas. Background Technology

[0002] It cannot be ignored that while the exploration and development of oil and gas resources brings enormous benefits to the social economy, it also causes certain pollution and damage to the surrounding ecological environment. Therefore, accurately grasping the ecological environment status of desert oil and gas field development areas and exploration areas, conducting long-term monitoring and scientific assessment of the ecological impacts of oil and gas field development, and carrying out targeted ecological restoration and governance are inevitable requirements for ecological civilization construction and an essential path for the green development of oil and gas field enterprises.

[0003] Desert areas are regions rich in oil and gas resources and where development activities are relatively intensive. These areas are characterized by arid climates, sparse vegetation (sometimes even bare ground), poor soil development, and a single ecological type, making their ecosystems extremely fragile and difficult to restore once damaged. Therefore, conducting ecological and environmental monitoring in desert oil and gas field development areas is of paramount importance.

[0004] Currently, remote sensing is widely used in ecological environment monitoring due to its convenience, speed, and wide coverage. Ensuring the reliability and accuracy of remote sensing monitoring results is the prerequisite and foundation for using remote sensing to conduct ecological environment monitoring in desert areas. Ground monitoring is the most direct method to verify the accuracy of remote sensing monitoring results, which is not difficult for most areas in China where fieldwork is relatively limited, labor is abundant, and distances are relatively short. However, conducting field ecological environment monitoring, primarily through on-site reconnaissance, involves a huge workload, difficulty, and financial investment, becoming the biggest obstacle to understanding and regularly monitoring the ecological and environmental impacts of oil and gas fields. Furthermore, globally, ecological and environmental data is most scarce in desert areas, which cover nearly one-third of the land area. This situation indicates that conducting ground-based observations, mainly by human intervention, to verify remote sensing monitoring data in desert areas does not meet the requirements of long-term, dynamic ecological monitoring, and suffers from problems such as low efficiency, non-repeatability, high investment, and even difficulty in promotion; thus limiting the implementation of long-term monitoring of the ecological and environmental impacts of oil and gas field production areas in desert regions by oil and gas companies.

[0005] With increasing national and local emphasis on ecological environment, some research has innovated remote sensing ecological monitoring methods and technologies. For example, CN118306591A discloses a drone-based integrated automated monitoring device for forest and grassland ecology. The advantage of this invention lies in its simplicity and ease of operation. Through the collaboration of the drone and the monitoring system, supplementary lighting is provided while the drone's altitude is determined by light refraction, reducing the possibility of drone collisions with trees and ultimately achieving data acquisition. CN105158413B discloses a method for establishing benchmark plots for remote sensing monitoring of alpine grasslands. By establishing fixed plots, information on vegetation, soil, topography, and interference from ground monitoring is used to provide more accurate interpretation information for hyperspectral remote sensing. However, these inventions only innovate in monitoring methods (such as drone design and plot monitoring content), and their applicability in desert areas is limited. They do not solve the problems of high cost and low efficiency in ground monitoring of the ecological environment of oil and gas fields in desert areas where labor is scarce and workspaces are scattered.

[0006] Therefore, how to reduce costs and achieve repeatable and verifiable ground-based monitoring to verify remote sensing monitoring results in accordance with the requirements of long-term and continuous monitoring of the ecological environment is a key issue that urgently needs to be addressed. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] Ecological environment monitoring in desert areas, which mainly relies on on-site surveys, suffers from low efficiency, high difficulty, and high cost. Remote sensing monitoring has overcome these problems, but its reliability needs to be verified. The purpose of this invention is to provide a method for constructing fixed sample plots to verify the results of remote sensing monitoring of oil and gas fields in desert areas, in order to solve the following problems under the condition of reducing manpower, capital and other costs: (1) how to set up ground fixed observation sample plots according to the characteristics of oil and gas field engineering development. Technically, the fixed monitoring sample plots need to be able to comprehensively reflect the impact of a certain oil and gas development project on the regional ecological environment, that is, including the project-affected area and the non-affected area; (2) on the basis of the above-mentioned fixed monitoring sample plots, to automatically realize two functions: First, to realize the automatic acquisition, storage and transmission of image information of each fixed sample plot. This part is mainly to obtain information such as vegetation coverage and vegetation greenness directly through cameras equipped with visible light, microwave and other sensors. The technical difficulty of this part is in the in-situ information acquisition, storage and remote acquisition; Second, some monitoring indicators (such as plant nutrient content, chlorophyll, etc.) are difficult to obtain directly by image technology alone. They must be realized through the testing of plant samples. Therefore, we need to solve the sample collection, preprocessing and storage. The technical difficulty of this part is how to realize the automatic collection of samples. The expected results are to improve monitoring efficiency, reduce costs, and cover as much ground monitoring data as possible (directly extracted image data + data dependent on test analysis), thereby verifying the reliability and accuracy of remote sensing monitoring results.

[0009] (II) Technical Solution

[0010] This invention provides a method for verifying remote sensing monitoring results of oil and gas fields in desert areas, namely, establishing a ground monitoring plot for a typical desert oil and gas field. The ground monitoring plot is centered on a specific oil and gas development project, with monitoring quadrats set up at different locations within the plot. Data such as vegetation, soil spectra, and plant growth are collected periodically using a data acquisition device. This device can simultaneously collect, preprocess, and store samples such as plant leaves.

[0011] To achieve the above-mentioned technical objectives, the present invention provides a method for constructing a typical surface monitoring plot in a desert oil and gas field, specifically including the following steps:

[0012] S1: Taking the oil and gas development project as the center, select a standard sample plot, which includes typical plant communities, topography and species characteristics around the oil and gas development project;

[0013] S2: Locate the coordinates of the standard sample plot and mark the coordinate position;

[0014] S3: Within the standard sample plot, monitoring plots are set up at the midpoints of the dividing lines between the first, second, and third preset distances from the oil and gas development project. Ground vegetation data auxiliary acquisition devices are installed in the monitoring plots to collect vegetation characteristic data. The average value of the vegetation characteristic data collected from each monitoring plot is then used as the basic vegetation condition data under the influence of the oil and gas project. The first, second, and third preset distances increase in sequence.

[0015] S4: Based on the comparison between the basic vegetation condition data obtained in S3 and the pre-acquired remote sensing monitoring data, verify the accuracy of the remote sensing monitoring results.

[0016] In S3, the first preset distance, the second preset distance, and the third preset distance are 100m, 200m, and 500m, respectively.

[0017] It also includes a remote monitoring center, which comprises:

[0018] A wireless communication module is used to receive vegetation characteristic data;

[0019] The data preprocessing module includes a filtering module and a classification module;

[0020] The filtering module is used to filter vegetation feature data and transmit vegetation feature data that meets the preset filtering conditions to the classification module for classification.

[0021] A ground plant data-aided acquisition device includes a rectangular shell. Two downward-facing inserts are symmetrically fixedly connected to the top of the shell, and an upward-facing bracket is fixedly connected to the top rear side of the shell. An image acquisition device is installed on the top of the bracket, and an electrical device electrically connected to the image acquisition device is installed inside the shell.

[0022] The shell is also equipped with a vegetation sample collection device, which is used to sample the vegetation in the monitoring plot to obtain vegetation samples for obtaining vegetation characteristic data.

[0023] The vegetation sample collection device includes a charging unit, and the charging unit is equipped with a drone sampling unit.

[0024] The side wall of the shell is provided with a sample collection section.

[0025] The charging unit includes a support plate horizontally disposed within the housing. The inner wall of the housing is symmetrically provided with limiting protrusions that cooperate with the bottom sides of the support plate. A vertically disposed telescopic device is fixedly connected between the bottom center of the support plate and the bottom inner wall of the housing. A wireless charging platform electrically connected to the electrical device is disposed on the top of the support plate. Limiting frames that cooperate with the sampling component of the UAV are symmetrically disposed on both sides of the top of the wireless charging platform.

[0026] The drone sampling component includes a drone body located on the wireless charging platform and within the limiting frame. The bottom of the drone body is provided with an electrical device 2 and a charging end that cooperates with the wireless charging platform.

[0027] A sampling tube with an open bottom is vertically arranged on one side of the main body of the drone. A frame is attached to the bottom of the sampling tube. A blade is horizontally arranged inside the frame. The cross-sectional area of ​​the blade is larger than the cross-sectional area of ​​the sampling tube. A telescopic device two is arranged inside the frame. The telescopic end of the telescopic device two is fixedly connected to the blade.

[0028] The sample collection part includes a support seat disposed on the outer wall of the housing. The bottom of the support seat extends into the housing from the side near the housing and is located between the sampling cylinder and the support plate. The support plate has a notch that mates with the portion of the support seat located inside the housing.

[0029] The support base is located at the top of the inner part of the housing and has a collection trough corresponding to the sampling cylinder. The inner wall of one side of the collection trough is connected to the output end of the adsorption device through a pipe. The adsorption device is located inside the support base and the output end of the adsorption device is provided with a pipe that penetrates the top of the support base. The top of the support base is provided with a sorting component that communicates with the pipe.

[0030] The sorting component includes a base plate fixedly and horizontally disposed on the top of the support seat. The base plate has a through hole communicating with the second pipe. A top plate disposed above the base plate and located on the same central axis as the base plate is provided. The top plate is connected to the output end of a rotating device, which is disposed inside the support seat.

[0031] The top plate has several containers arranged in a circular array to communicate with the through holes. The bottom of each container is fitted with a wear-resistant rubber sealing ring that contacts the top of the base plate. The containers are connected to the top plate by snaps or threads. Both sides of the bottom of the inner cavity of each container are symmetrically hinged with sealing plates to close the bottom of the container. The sealing plates are connected to the inner wall of the container by arc springs to drive the rotating sealing plates to return to their original position.

[0032] The container is made of a heat-conducting material, and an insulated cup is fitted on the outer wall of the container. The insulated cup is made of an insulated material.

[0033] The top of the housing is symmetrically and slidably connected to two sides of a cover plate for sealing the top of the housing. A rack, extending along the length of the cover plate, is embedded in the bottom of each cover plate. A gear meshes with the outer bottom end of the rack. The gear is rotatably connected to the outer wall of the housing via a gear shaft and a torsion spring. A pull rope is wound around the outer side of the gear shaft. The pull end of the rope passes through the bottom of the side wall of the housing and extends to the inner side of the housing, connecting with a support plate. Guide pulleys, cooperating with the pull rope, are provided on both the outer and inner walls of the housing. When the support plate is moved upwards, pulling the rope drives the gear shaft to rotate the gear. The gear then drives the rack to move the cover plate away from the center of the housing.

[0034] Both the electrical device one and the electrical device two include a controller. The controller in the electrical device one is used to control the electrical components on the shell, and the controller in the electrical device two is used to control the main body of the drone and the electrical components outside it.

[0035] The side wall of the bracket is equipped with a photovoltaic power supply device.

[0036] The beneficial effects of this invention are as follows:

[0037] 1. Long-term and accurate ground monitoring data is an effective method to verify the reliability and accuracy of remote sensing data. Based on a comprehensive consideration of the inherent properties of vegetation and soil in desert areas, this invention adopts the "distance-effect" plot layout approach, covering both the ecological and environmental impact areas and non-impact areas of oil and gas development. This can reduce the impact of spatial heterogeneity of vegetation and soil on monitoring results and remote sensing accuracy, thereby improving the quality of ecological impact assessment of oil and gas development.

[0038] 2. Based on fixed monitoring plots, it takes into account both image information collection and physical sample collection. It can not only realize the automated monitoring, storage and transmission of basic information such as plant cover and greenness, but also specifically designed a module for the collection, classification and storage of plant physical samples by drones. This provides the conditions for carrying out more comprehensive monitoring of the ecological impact of oil and gas field development, such as plant growth status and physiological response, while reducing the frequency of field surveys. It fundamentally solves the problem of high manpower cost and large workload in long-term and dynamic ecological monitoring of oil and gas field ecosystems in desert areas.

[0039] 3. The design of fixed sample plots centered on oil and gas field projects in specific desert areas, taking into account both the ecological and environmental impact zones and non-impact zones of oil and gas projects, can accurately reflect the differences in the types and intensity of ecological and environmental impacts brought about by oil and gas field projects in different regions, and improve the ability to verify the remote sensing monitoring results of the ecological impacts of oil and gas field development.

[0040] 4. Based on the fixed sample plots for ecological monitoring, an automatic monitoring module (image information acquisition part) for parameters such as plant growth has been added. This can reduce the number of personnel required for ecological monitoring in desert areas and the number of field trips and workload, thus saving costs. More importantly, the added module for collecting and storing physical samples such as plant leaves and branches can achieve unattended operation and on-demand sample collection (preset frequency or remote control at specific time points) without increasing additional costs, reducing the potential environmental impact of repeated field investigations.

[0047] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.

[0048] Example 1:

[0049] Please see the appendix Figure 1

[0050] A method for verifying remote sensing monitoring results of oil and gas fields in desert areas includes the following steps:

[0051] S1: Centered on oil and gas development project a, select standard sample plot 1 with an area of ​​1 square kilometer (the area of ​​the sample plot can be expanded if the oil and gas field development project occupies a large area). The boundary of standard sample plot 1 is more than 500 meters away from the boundary of the project, ensuring that the standard sample plot covers all areas affected by the oil and gas development project and extends to areas without impact. The standard sample plot 1 includes typical plant communities, topography and species characteristics around the oil and gas development project.

[0052] S2: Locate the coordinates of standard sample plot 1 and mark them with wooden stakes to facilitate ground monitoring at any time later;

[0053] S3: Within standard sample plot 1, monitoring plot 2 is set at the midpoint of the dividing line between the first, second, and third preset distances from the oil and gas development project. The first, second, and third preset distances increase in sequence. The size of monitoring plot 2 is 20m×20m (the size of herbaceous plant plot is 1m×1m). Ground plant data auxiliary acquisition device 3 is installed in monitoring plot 2 to collect vegetation characteristic data within monitoring plot 2. Then, the average value of the vegetation characteristic data collected from each monitoring plot 2 is used as the basic vegetation condition data under the influence of the oil and gas project.

[0054] The aforementioned vegetation characteristic data may include, for example, vegetation chlorophyll content, fiber content, etc., or vegetation height, quantity, canopy width, coverage, and biomass, etc.

[0055] S4: Based on the comparison of the basic vegetation condition data obtained in S3 with the pre-acquired remote sensing monitoring data, verify the accuracy of the remote sensing monitoring results based on the comparison results;

[0056] The aforementioned pre-acquired remote sensing monitoring data are vegetation data of the oil and gas development project area obtained using existing remote sensing equipment, such as sensors or remote sensors, and will not be described in detail here.

[0057] Preferably, the first preset distance, the second preset distance, and the third preset distance in this embodiment are 100m, 200m, and 500m, respectively (as a control area unaffected by engineering).

[0058] Preferably, this embodiment also includes a remote monitoring center, which includes:

[0059] A wireless communication module is used to receive vegetation characteristic data;

[0060] The data preprocessing module includes a filtering module and a classification module;

[0061] The filtering module is used to filter vegetation feature data and transmit vegetation feature data that meets the preset filtering conditions to the classification module for classification.

[0062] Both the filtering and classification modules are existing conventional technologies. The filtering module removes data items that do not meet the requirements or are incorrect, such as missing values, outliers, or data with incorrect formats, thereby improving the overall quality and reliability of the data. The classification module, for example, classifies vegetation characteristic data of the same time period and / or the same type, so as to quickly retrieve and calculate the average value of the vegetation characteristic data.

[0063] Example 2:

[0064] Please see the appendix Figure 2 -Appendix Figure 3

[0065] A ground plant data collection auxiliary device includes a rectangular shell 31. Two downward-facing inserts 32 are symmetrically fixedly connected to the shell 31. An upward-facing bracket 33 is fixedly connected to the rear top of the shell 31. An image acquisition device 34 is installed on the top of the bracket 33. An electrical device 36 electrically connected to the image acquisition device 34 is installed inside the shell 31. The inserts 32 are, for example, cones, to ensure that the ground plant data collection auxiliary device 34 is stably positioned within the monitoring plot 2. The image acquisition device 34 is, for example, a camera, which can assist users in collecting ground data.

[0066] The shell 31 is also equipped with a vegetation sample collection device, which is used to sample the vegetation in the monitoring plot 2 to obtain vegetation sample for obtaining vegetation characteristic data. By performing corresponding tests on the obtained vegetation sample, the required vegetation characteristic data can be obtained, such as vegetation chlorophyll content, fiber content and other data.

[0067] The vegetation sample collection unit includes a charging unit, on which a drone sampling unit is installed;

[0068] A sample collection section is provided on the side wall of the shell 31.

[0069] Example 3:

[0070] Please see the appendix Figure 4 -Appendix Figure 5

[0071] The charging unit includes a support plate 38 horizontally disposed within a housing 31. Symmetrical limiting protrusions 39, which mate with the bottom sides of the support plate 38, are arranged on both sides of the inner wall of the housing 31. A vertically arranged telescopic device 37 is fixedly connected between the bottom center of the support plate 38 and the bottom inner wall of the housing 31. A wireless charging platform 310, electrically connected to an electrical device 36, is disposed on the top of the support plate 38. Limiting frames 312, mate with the drone sampling component, are symmetrically arranged on both sides of the top of the wireless charging platform 310. The telescopic device 37 is, for example, a telescopic rod. The telescopic device 37 drives the support plate 38 to move the wireless charging platform 310 upwards to a designated position. The limiting frames 312 restrict the position of the drone sampling component on the wireless charging platform 310.

[0072] The drone sampling component includes a drone body 313 located on a wireless charging platform 310 and within a limiting frame 312. An electrical device 314 and a charging end 315 that cooperates with the wireless charging platform 310 are provided at the bottom of the drone body 313. The drone body 313 is charged by cooperating with the wireless charging platform 310 through the charging end 315. This is existing technology and will not be described in detail here.

[0073] A sampling tube 316 with an open bottom is vertically arranged on one side of the main body 313 of the drone. A frame is attached to the bottom of the sampling tube 310. A blade 317 is horizontally arranged inside the frame. The cross-sectional area of ​​the blade 317 is larger than the cross-sectional area of ​​the sampling tube 316. A telescopic device 318 is arranged inside the frame. The telescopic end of the telescopic device 318 is fixedly connected to the blade 317. In use, the main body of the drone 313 is controlled to fly to the vegetation area of ​​the monitoring plot 2, so that some of the stems and leaves of the vegetation extend into the sampling tube 316. Then, the blade 317 is moved by controlling the telescopic device 318 to cut the stems and leaves of the vegetation, so that the stems and leaves of the vegetation that have extended into the sampling tube 316 remain in the sampling tube 316, thereby completing the sampling of vegetation samples. After the main body of the drone 313 has taken samples, it can be controlled to fly to the required location, such as controlling the main body of the drone 313 to fly back to the laboratory, so that the users can test the collected vegetation samples and obtain the required vegetation characteristic data, eliminating the trouble of manually going to the monitoring plot 2 to collect vegetation samples.

[0074] It can also control the main body of the drone 313 to fly back to the wireless charging platform 310. After the main body of the drone 313 flies back to the wireless charging platform 310, its sampling tube 316 and sample collection part are in a corresponding state.

[0075] The sample collection part includes a support seat 322 disposed on the outer wall of the housing 31. The support seat 322 is L-shaped. The bottom of the support seat 322 extends into the housing 31 near the housing 31 and is located between the sampling cylinder 316 and the support plate 38. The support plate 38 has a notch that partially mates with the support seat 322 located inside the housing 31, so that the support seat 322 does not obstruct the up and down movement of the support plate 38.

[0076] The top of the support 322 located inside the housing 31 is provided with a collection trough 323 corresponding to the sampling cylinder 316. The inner wall of one side of the collection trough 323 is connected to the output end of the adsorption device 311 through a pipe. The adsorption device 311 is, for example, an induced draft fan. The adsorption device 311 is located inside the support 322 and the output end of the adsorption device 311 is provided with a pipe second that penetrates through the top of the support 322. The top of the support 322 is provided with a sorting component that communicates with the pipe second.

[0077] If the drone body 313 is unable to fly back to the laboratory due to external weather conditions (such as strong winds) or its own factors (battery life), the user can control the drone body 313 to collect plant samples multiple times in the area and classify and preserve the collected plant samples using a classification device so that they can be taken back by the user for unified testing later.

[0078] The sorting component includes a base 327 fixedly and horizontally mounted on top of the support 322. The base 327 has a through hole 324 communicating with the second pipe. A top plate 326 is mounted above the base 327 and is on the same central axis. The top plate 326 is connected to the output end of a rotating device 325. The rotating device 325 is located inside the support 322. The rotating device 325 is, for example, a servo motor and a reducer. The top plate 326 is slidably connected to the base 327, for example, by using a slider and a slide rail.

[0079] The top plate 326 has several containers 328 arranged in a circular array for communicating with the through holes 324. The bottom of each container 328 is fitted with a wear-resistant rubber sealing ring that contacts the top of the base plate 327. The containers 328 and the top plate 326 are connected by snap-fit ​​or threaded connections for easy assembly and disassembly. The bottom sides of the inner cavity of each container 328 are symmetrically hinged with sealing plates 329 for sealing the bottom of the container 328. The sealing plates 329 are flush with the inner wall of the container 328. The sealing plate 329, which is driven to rotate, is reset via an arc spring. In use, the top plate 326 is driven to rotate by the rotating device 325, so that different placement containers 328 are aligned with the through hole 324. After alignment, the adsorption device 311 is opened, and under the gas drive, the sealing plate 329 in the placement container 328 of the through hole 324 flips inward and opens, allowing the vegetation sample to enter the placement container 328. When the adsorption device 311 is closed, the sealing plate 329 is reset under the action of the arc spring.

[0080] The placement container 328 is made of a heat-conducting material, such as copper, aluminum, or iron. The outer wall of the placement container 328 is fitted with an insulating cup 330, which is made of heat-insulating material. Considering that the device is located in a desert area, after the vegetation sample enters the placement container 328, the placement container 328 can absorb heat and transfer it to the vegetation sample inside, so that the vegetation sample is dried, in order to maintain the stability of the shape and color of the vegetation sample and extend its shelf life. The setting of the insulating ring 330 makes it easy to manually disassemble the placement container 328, and personnel can periodically go to the monitoring plot 2 to collect the vegetation sample from the placement container 328.

[0081] The top two sides of the housing 31 are symmetrically slidably connected to cover plates 319 for closing the top of the housing 31. The bottom of the cover plate 319 is embedded with a rack arranged along the length of the cover plate 319. The bottom outer end of the rack is engaged with a gear 320. The gear 320 is rotatably connected to the outer wall of the housing 31 through a gear shaft and a torsion spring. A pull rope 321 is wound around the outside of the gear shaft. The pulling end of the pull rope 321 passes through the bottom of the side wall of the housing 31 and extends to the inside of the housing 31 to connect with the support plate 38. The outer wall and inner wall of the housing 31 are provided with guide pulleys that cooperate with the pull rope 321. When the support plate 38 is upward, the pull rope 321 is pulled to drive the gear shaft to drive the gear 320 to rotate. The gear 320 drives the rack to move the cover plate 319 to the side away from the center of the housing 31. It should be noted that when the support plate 38 is upward, the cover plate 319 is open, and when the support plate 38 is downward, the cover plate 319 is closed, which protects the internal structure of the housing 31.

[0082] Both electrical device 1 36 and electrical device 2 314 include controllers. The controller in electrical device 1 36 is used to control the electrical components on the housing 31, such as telescopic device 1 37, rotating device 325, adsorption device 311, etc. The controller in electrical device 2 314 is used to control the main body of the UAV 313 and its external electrical components, such as telescopic device 2 318. Electrical device 1 36 and electrical device 2 314 can specifically achieve remote wireless communication with the wireless communication module of the remote monitoring center, so that personnel can remotely control the electrical components in the ground plant data auxiliary acquisition device 3 to work.

[0083] The side wall of the support 33 is provided with a photovoltaic power supply device 35, which includes, for example, a power supply battery and a photovoltaic panel, so as to supply power to the electrical components of the ground plant data auxiliary acquisition device 3.

[0084] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
