Description

Technical Field

[0001] The invention belongs to the technical field of information management and control of crude oil production well sites, and in particular relates to a crude oil anti-internal theft system for a test production well site based on electronic locks and electronic lead seals. Background Art

[0002] For crude oil test production sites in remote areas without network signals, the test wellheads currently basically use mechanical locks, which are easy to damage and easily opened illegally, and the ability to control abnormal replacement of oil nozzles is weak; the well site storage tanks lack control measures, and the oil filling port, sewage outlet, and maintenance port are all prone to the risk of crude oil theft, especially the sewage outlet, which is a key risk point for crude oil theft throughout the year; the sealing process of oil tanker trucks is relatively simple, and the seals are easy to counterfeit. The seal ledger and verification information are filled in manually, and the ability to control personnel and vehicle information is weak, and there is a risk that crude oil theft cannot be accurately identified. Summary of the invention

[0003] In view of the above problems, the design concept of the present invention is as follows:

[0004] 1. In terms of controlling the nozzle and production, the present invention replaces the traditional mechanical locks with explosion-proof smart wifi locks. Traditional mechanical locks are easy to be illegally cracked and damaged, and illegal replacement of nozzles often occurs. With explosion-proof smart wifi locks, only the nozzle operation can be applied for in advance, and after approval, the on-site personnel can remotely unlock or the operator can unlock with a password. Abnormal behaviors such as damage to the lock, wrong password, and unauthorized unlocking will trigger an alarm. A ledger will be established for each unlocking and blocking, so that each operation can be traced, which greatly reduces the occurrence of illegal replacement of nozzles and controls the abnormal increase in crude oil production.

[0005] 2. In terms of controlling the test well site storage tanks, the present invention is equipped with explosion-proof Bluetooth electronic locks at the top inspection port of the storage tank, the bottom sewage outlet, and the crane mouth of the oil filling pump. The explosion-proof Bluetooth electronic lock has an RFID (radio frequency identification) tag. The unlocking personnel are identified according to the RFID tag. The tag is unique and can identify the maintenance, oil filling, and sewage discharge personnel, ensuring the uniqueness of the oil outlet during oil filling, preventing the risk of illegal elements stealing oil from other oil outlets. Compared with the traditional storage tank management method, the risk of crude oil theft is reduced. At the same time, for maintenance and sewage discharge operators, management is strengthened to avoid unqualified practitioners from taking up their posts for maintenance and sewage discharge, reducing the occurrence of safety hazards. In addition, a ledger will be established for each operation to make the business traceable. Behaviors such as destroying electronic locks and unauthorized unlocking will be warned to avoid violent unlocking and theft. The traditional storage tank management model basically relies on human defense, and there are no defense measures at each filling port.

[0006] 3. In terms of the management and control of transport vehicles and transport personnel, the traditional management mode is that the personnel and vehicle information is recorded in paper forms, which has limitations and is easy to tamper with. When loading and unloading oil tankers, it is impossible to accurately verify the vehicles and personnel, and the lead seals are easy to forge, and the theft of crude oil on the way cannot be accurately verified. In the present invention, the above-mentioned Bluetooth electronic lock is used to seal the tanker. The Bluetooth electronic lock is equipped with an RFID tag, and a Bluetooth electronic lock ledger is set. It is necessary to identify whether it is our electronic lock to prevent counterfeiting, and record the personnel and vehicle information through the information platform. When sealing, this information is bound to the Bluetooth electronic lock. When unsealing, only specific unsealing personnel can unseal through a handheld terminal. By checking the integrity of the Bluetooth electronic lock, it is determined whether the crude oil is unsealed during transportation. By pairing the handheld terminal with the RFID tag, the vehicle and personnel information can be compared to determine whether the personnel and vehicle are wrong, avoiding the loading and unloading of oil by outsiders and vehicles.

[0007] 4. In terms of transport vehicle control during transportation, each vehicle is equipped with the Beidou system to check the vehicle trajectory and route in real time. Vehicles that stop abnormally for a long time or change routes during transportation will be judged as suspicious vehicles that have stolen oil.

[0008] 5. In terms of crude oil transportation management, the unloading personnel should check in advance whether the locks are damaged, and determine whether the locks have been replaced by scanning the RFID tags, and whether the oil tanks have been unsealed abnormally during transportation. For thefts that directly replace the oil tanks, it can be determined by directly checking whether the tank trucks are equipped with Bluetooth electronic locks. In the traditional transportation mode, there are no effective measures in this regard.

[0009] The specific technical scheme adopted by the present invention is as follows: a crude oil anti-internal theft system for a test well site based on electronic locks and electronic seals, the system comprising an oil nozzle operation application module, an oil loading and unloading processing module, a ledger management module, an electronic lock management module and an early warning module; wherein the oil nozzle operation application module is used to apply for unlocking, replacing the oil nozzle operation, and sealing after the oil nozzle operation is completed; the oil loading and unloading processing module is used to operate the sealing and unsealing of the loading and unloading oil; the ledger management module is used to establish an unlocking and blocking ledger for loading and unloading oil; the electronic lock management module is used to control the oil nozzle operation and the sealing and unsealing of the loading and unloading oil; the early warning module is used to monitor and alarm the crude oil transfer process.

[0013] The explosion-proof Bluetooth electronic lock is used to unseal the oil filling port, oil sealing port and top tank port of the oil tanker. The unsealing personnel unseal the tanker through a handheld terminal and check whether the Bluetooth electronic lock is intact to determine whether the crude oil has been opened and stolen during transportation. The handheld terminal is paired with the radio frequency identification tag to compare the vehicle and personnel information to determine whether the personnel and vehicle are incorrect.

[0014] Furthermore, the explosion-proof smart wifi lock is used to control the operation of the fuel nozzle, including: the explosion-proof smart wifi lock is used to unseal the fuel nozzle, record the unsealing method and unsealing time, and establish a fuel nozzle replacement ledger.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] A crude oil anti-theft system based on electronic locks and electronic seals for test well sites, such as Figure 1 As shown, the system includes an oil nozzle operation application module, an oil loading and unloading processing module, a ledger management module, an electronic lock management module and an early warning module; the oil nozzle operation application module is used to apply for unlocking, replacing the oil nozzle operation, and sealing the oil nozzle after the operation is completed; the oil loading and unloading processing module is used to operate the sealing and unsealing of the loading and unloading oil; the ledger management module is used to establish the unlocking and blocking ledger of the loading and unloading oil; the electronic lock management module is used to control the oil nozzle operation and the sealing and unsealing of the loading and unloading oil; the early warning module is used to monitor and alarm the crude oil transfer process.

[0034] Among them, the nozzle operation application module is used for the operator to apply for unlocking the wellhead electronic lock in the test well site crude oil anti-theft system, and after being reviewed and approved by the person in charge of the oil and gas production area, the nozzle can be unlocked and replaced in two ways within the specified operation time period through remote unlocking or one-time password authorization by the on-site terminal, and the sealing operation is carried out in time after the operation is completed. The above unlocking and sealing operations are recorded in the log, and the acts of destruction, password guessing, etc. can be recorded and transmitted remotely to the oil and gas production area.

[0035] The inspection port on the top of the tank, the bottom sewage outlet, and the loading skid bypass are all sealed with electronic seals. If the tank needs to be guided or a fault is repaired, the crude oil inlet valve of the tank is closed and an electronic seal is set. Electronic seals are added to the inspection port on the top of the tank, the bottom sewage outlet, the oil inlet of the faulty tank, the bypass valve of the tank outlet, etc., and the seal unlocking authority is only granted to the oil production workers in this block. Ensure that the tank has only one oil outlet, and the oil output is monitored by the loading skid flow meter.

[0036] Scenario description: Input basic information such as the number of storage tanks, storage tank capacity, nozzle model, water content, density, etc., and collect tank level data (collected every 5 minutes) and loading skid flow data in real time while the working system remains unchanged (nozzle model remains unchanged); calculate the additional storage volume of the tank based on the tank level difference from 8:00 a.m. to 8:00 a.m. the next day, and add the loading volume to get the daily liquid production of the test well or centralized test point, and then match the latest experimental data such as water content and density to calculate the daily production of the test well. Verify the daily production changes while the working system remains unchanged (no nozzle changes), and immediately trigger an alarm if the changes exceed the specified range. Under the condition of stable production, calculate the tank level data for a period of time (about 15 minutes, which is less than the time to fill a truck with oil). If the real-time collected tank level data is lower than the expected value and continues to decrease in the next expected stage, the oil theft alarm will be triggered, prompting the monitoring personnel to check the video monitoring information. At the same time, during the normal oil filling process, the loading volume can also be calculated through the expected liquid level, real-time liquid level, etc., and compared with the loading flow meter. If it exceeds a certain range, it is judged that the flow meter or level meter is faulty.

[0037] Among them, the liquid storage volume of the storage tank = storage tank liquid level * storage tank volume index; the daily production of a single test well = (storage tank liquid level difference * storage tank volume index + cumulative loading skid flow) * test well density * (1-test well water content).

[0038] The lead seal authorization for storage tanks and loading skid bypasses is limited to the person in charge of oil production in this area. The nozzle operation application module is also used by operators in the test well site crude oil anti-theft system to apply for the unsealing of storage tanks and skid bypasses sealed with practical electronic seals. After approval by the business department, the oil nozzle replacement operation can be performed by remote unlocking or one-time password authorization of the on-site terminal within the specified operation time period, and the sealing operation is carried out in time after the operation is completed. The above operation can effectively ensure that the storage tank has only normal oil outlets to prevent oil theft from other illegal outlets.

[0039] The oil loading and unloading processing module is used for the oil loading and unloading personnel to perform sealing and unsealing operations on the explosion-proof handheld terminal during oil loading and unloading, and to form a record log at the same time.

[0040] The electronic lock management module includes an explosion-proof Bluetooth electronic lock, an explosion-proof handheld terminal and an explosion-proof smart wifi lock; the explosion-proof Bluetooth electronic lock innovatively adds an RFID tag on the basis of an ordinary electronic lock, which can uniformly identify and authenticate each Bluetooth electronic lock to prevent counterfeiting. Use explosion-proof Bluetooth electronic locks to replace ordinary lead seals, seal the oil filling port, oil sealing port, and top tank port of the tank truck, and it cannot be unsealed without destroying the lock body during transportation to ensure transportation safety; when unloading oil, the explosion-proof Bluetooth electronic lock RFID tag is used for authentication. The entire use process of the explosion-proof Bluetooth electronic lock is recorded. The explosion-proof Bluetooth electronic lock is also equipped with a Bluetooth electronic lock ledger, in which the RFID tag is used to determine whether the oil tank has been abnormally unsealed and whether the Bluetooth electronic lock has been replaced. For theft of replacing oil tanks, the RFID tag can also be used to directly check whether the tank truck is equipped with an explosion-proof Bluetooth electronic lock; the Bluetooth electronic lock ledger is used to record personnel and vehicle information. Specifically, when the oil filling port, oil sealing port and top tank port of the oil tanker are sealed, the explosion-proof Bluetooth electronic lock is used to bind the personnel and vehicle information to the Bluetooth electronic lock; when the oil filling port, oil sealing port and top tank port of the oil tanker are unsealed, the explosion-proof Bluetooth electronic lock is used to be unsealed by the unsealing personnel through a handheld terminal, and by checking whether the Bluetooth electronic lock is intact, it is determined whether the lock has been opened and the crude oil has been stolen during transportation; the handheld terminal is paired with the RFID tag to compare the vehicle and personnel information to determine whether the personnel and vehicle are incorrect.

[0041] The specific working method of explosion-proof Bluetooth electronic lock is as follows Figure 2 As shown, before loading oil, the explosion-proof Bluetooth electronic lock is in the stopped state. After confirming that the loading personnel and vehicles are correct, the staff will lock the lock, and the explosion-proof Bluetooth electronic lock will be switched to the standby state. The personnel and vehicle information will be recorded to form a ledger, and the lock will be sealed, and the explosion-proof Bluetooth electronic lock will be switched to the armed state. After arriving at the oil unloading destination, the unloading personnel will unseal the lock through the handheld terminal. If the identification of personnel information, vehicle information and loading is correct, the explosion-proof Bluetooth electronic lock will be switched to the disarmed state. After unlocking, it will be switched to the stopped state. If the identification information is incorrect, the alarm will be started, and the explosion-proof Bluetooth electronic lock will be switched to the alarm state. After the staff has dealt with the accident accordingly, the alarm will be lifted, and the explosion-proof Bluetooth electronic lock will be switched to the disarmed state. After unlocking, it will enter the stopped state.

[0042] The workflow of electronic lead seal ledger is as follows Figure 3As shown in the figure, it is divided into seven steps: lead seal issuance, registration, oil loading and sealing, oil unloading and unsealing, data verification, data reporting and report generation. Specifically, the personnel and vehicle arrangements in the crude oil transportation task are issued by the dispatcher, and the information of the vehicles and personnel involved in oil pulling is sent to the handheld terminal of the test well operator every day. The test well operator manually checks the oil loading personnel and vehicles, confirms them at the terminal after they are correct, and opens the terminal to carry out oil loading operations. The confirmation information, lead seal unlocking, and sealing information timestamp can record the time when the vehicle enters, loads, and loads oil, forming a record of personnel and vehicles in the test well operation. When the vehicle enters the oil unloading point, the heavy vehicle weighing information and weighing time, the lead seal verification, unsealing time, sealing time, and the light vehicle weighing information and weighing time can form a record of personnel and vehicles at the oil unloading platform, and compare them according to the loading and unloading quantities. If they are outside the specified input difference range, the oil leakage alarm on the way is triggered. The transit time is calculated based on the sealing time of the test mining point and the weighing time of the heavy vehicle, and compared with the standard time, triggering an alarm for excessive transit time. Using big data, the vehicle personnel ledger is compared to automatically count suspicious phenomena such as excessive transit time of vehicles, excessive difference in loading and unloading oil, etc., and the suspicious phenomena are ranked to indicate possible risks of oil theft.

[0043] The explosion-proof smart wifi lock improves the general hard steel into a wire lock rod so that it can be used on the irregular lock buckle at the wellhead. The explosion-proof smart wifi lock has a variety of unlocking operation methods (such as Figure 4 As shown in the figure, unseal the nozzle in different environments, record the unseal method and specific unseal time, and establish a nozzle replacement account. Figure 4 As shown, the explosion-proof smart wifi lock can be unlocked by remote control of the platform or manually apply for a dynamic password on site and unlocked by entering the dynamic password; when the platform issues a remote unlocking command to the wifi electronic lock, the wifi electronic lock must remain online. Figure 5 The working method of the explosion-proof smart wifi lock is shown, which is divided into three stages: loading, sealing and unsealing at the destination, specifically: after loading, the driver locks the wifi electronic lock in the correct keyhole of the cabinet door and checks the power, and then presses and holds "off" to seal locally; after local sealing, the electronic lock cannot be opened on site, but the unsealing command can be issued through the background wifi network to unblock or the password can be unblocked; then the background sends a sealing command, and the background password covers the local sealing password; when the vehicle arrives at the destination, the consignee enters the last 6 digits of the password when the platform sealed it to unblock, or unblocks it remotely through the wifi platform network; if the unsealing is normal, the lock is unlocked and the goods are unloaded; if the unsealing is abnormal, it means that the lock body is out of power or abnormal unlocking occurs (such as incorrect password input, violent unlocking, etc.) to trigger an alarm. If the lock body is out of power, plug in the emergency power supply to unlock it; if an alarm is triggered, it can be unlocked after disposing of it according to the actual situation and removing the alarm.

[0044] Specifically, the early warning module monitors and alarms the entire crude oil transfer process, including vehicle trajectory, abnormal parking, abnormal transmission difference, tank liquid level, and electronic seal abnormality alarm light; the early warning module can also alarm abnormal conditions in the operation records of the wellhead electronic lock, such as wrong password, application for unblocking, unauthorized, low voltage, open alarm and other records. The early warning module includes a vehicle Beidou monitoring unit, which is used to view the vehicle trajectory and route in real time, and determine suspicious vehicles with oil theft behavior based on the vehicle trajectory and route. For example, a vehicle that stops abnormally for a long time on the way and changes its route will be determined by the vehicle Beidou monitoring unit as a suspicious vehicle with oil theft behavior.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
