[0052] Figure 2 This is a flow chart of the data transmission method of the oil field single well production test system of the present invention. DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0054] In order to solve the technical problem that the existing method is economical and convenient and meets the needs of real-time data transmission, but its data transmission rate is low, which reduces the timeliness of the client receiving oil well data and increases the risk factor of oil well testing, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0055] The data transmission device of the oilfield single well production test system includes:

[0056] The data collection unit is a variety of collection equipment installed at the oil well site, which is used to collect various oil well data in real time and feed back various data to the first SR700 router at a regular interval; the data collection unit includes:

[0057] The parameter acquisition module includes: a temperature sensor, a pressure sensor and a liquid level sensor, which are used to collect temperature data, pressure data and liquid level data at the oil well site in real time; specifically, the temperature data, pressure data and liquid level data at the oil well site include: wellhead oil temperature, wellhead oil pressure, wellhead casing pressure, formation pressure, bottom hole flow pressure, wellhead tubing pressure, casing pressure, back pressure of the oil gathering pipeline and stratified formation pressure; the temperature data includes: wellhead oil temperature, which is an important indicator for monitoring the temperature of the oil well and helps to understand the working status and potential problems of the oil well; the pressure data involves multiple key indicators, such as: wellhead oil pressure, wellhead casing pressure, formation pressure, bottom hole flow pressure, wellhead tubing pressure and casing pressure, the above data reflect the pressure conditions inside the oil well, and can effectively prevent accidents such as blowouts; the liquid level data includes: back pressure of the oil gathering pipeline and stratified formation pressure, which are directly related to the output and mining efficiency of the oil well, and have a guiding role in optimizing the mining strategy, ensuring the stability and safety of the oil well operation.

[0058] The data cleaning module is used to clean the collected oil well data, eliminate errors and duplicate data, and use the median method to supplement the missing data; specifically, data cleaning is to further ensure the accuracy of various oil well data, thereby providing data support for warnings of abnormal conditions in oil wells.

[0059] The first feedback module is electrically connected to the first SR700 router, and is used to periodically feed back various data after cleaning processing to the first SR700 router; specifically, by configuring the first SR700 router for the parameter acquisition module, the real-time data of the oil well and the video can be fed back separately to prevent network congestion and data loss on both sides.

[0060] The video monitoring unit is a video monitoring device installed at the oil well site, used to record the video of the oil well site, monitor the operation of the oil well site in real time, and feed back the video of the oil well site to the second SR700 router; the video monitoring unit includes:

[0061] The video acquisition terminal is deployed at the oil well site to shoot real-time video of the oil well site, thereby obtaining the broadcast image of the oil well test production site, so that the client can view the oil well test production site conditions in real time.

[0062] The second feedback module is electrically connected to the second SR700 router and is used to feed back the daily oil well site video to the second SR700 router on a regular basis; specifically, it has the same function as the first feedback module, and is mainly used to feed back the oil well live data and video separately to prevent network congestion and data loss on both sides.

[0063] The interval setting unit is used to preset the transmission interval time node for the two SR700 routers in advance according to the oil well test production duration, and control the two SR700 routers to transmit data at the specified time node; the interval setting unit includes:

[0064] The time setting module is used to set the starting and ending time of daily collection and shooting for the data acquisition unit and the video monitoring unit in advance based on the oil well trial production duration and time point; specifically, the total daily collection duration and the collection start and end time are set for each collection sensor device and video collection terminal through the oil well trial production date and time assigned by the oil well trial production system, so that when the oil well trial production system is in a resting state, while ensuring that the oil well site can be effectively monitored, some of the sensor devices and video collection terminals can be selectively turned off, thereby increasing the service life of each sensor device and video collection terminal and reducing electricity investment costs.

[0065] The first information acquisition module is used to extract the total acquisition time and the start and end points of the acquisition time of the data acquisition unit and the video surveillance unit as the first information data; specifically, the first information data is obtained mainly to understand the daily working time efficiency of the data acquisition unit and the video surveillance unit, so as to determine the time node required for feedback according to the working time efficiency of each device.

[0066] The second information acquisition module is used to extract the time nodes when the two SR700 routers receive data and video each time as the second information data; specifically, the first information data is obtained, which is mainly used to further break the time point when each SR700 router specifically receives data or video, so that after any SR700 router receives valid data, it can be fed back to the cloud server as soon as possible.

[0067] The interval node setting module is used to extract the time elements of the first information data and the second information data, and preset the interval time nodes for the two SR700 routers to transmit data and video to the cloud server respectively; specifically, the working time and the time point of receiving data of each SR700 router are known according to the time elements of the first information data and the second information data, and the time point when each SR700 router receives data is used as the basis, and it is postponed 30s as the interval transmission time node, thereby configuring each SR700 router with transmission time nodes of different time periods; when each SR700 router is not in the transmission time node, it can be in standby state, thereby reducing power consumption and ensuring the service life of each SR700 router.

[0068] The wireless transmission unit transmits the oil well data and on-site video received by the two SR700 routers to the cloud server at specified intervals based on wireless transmission technology; the wireless transmission unit includes:

[0069] The network distance preset module is used to obtain the gateway communication distance parameters between the two SR700 routers and the cloud server respectively, and pre-set the normal gateway communication distance parameters between the two SR700 routers and the cloud server according to the distance parameters as the network distance threshold; specifically, by setting the network distance threshold, it is easier to understand the network communication status between the two SR700 routers and the cloud server respectively, so that the SR700 routers with good network communication status can be given priority transmission, reducing the waiting time for simultaneous data transmission and improving the efficiency of data transmission.

[0070] The network distance processing module is used to determine whether the gateway communication distance parameters between the two SR700 routers and the cloud server are within the network distance threshold range, and make corresponding processing instructions accordingly; in this embodiment, for example: the network distance threshold is preset as 1-15 kilometers through the network distance preset module, and the gateway communication distance parameter between the first SR700 router and the cloud server is obtained as 12 kilometers, thereby concluding that the first SR700 router is 12 kilometers away from the cloud server; through comparison, it is shown that the gateway communication distance parameter between the first SR700 router and the cloud server is within the network distance threshold range; therefore, the current first SR700 router can directly feed back the received oil field data and video to the cloud server through wireless transmission technology; for example: the gateway communication distance parameter between the second SR700 router and the cloud server is obtained as 18 kilometers through the network distance preset module, thereby concluding that the second SR700 router is 16 kilometers away from the cloud server; through comparison, it is shown that the gateway communication distance parameter between the second SR700 router and the cloud server exceeds the network distance threshold range.

[0071] The first priority setting module is used to obtain the gateway communication distance status between the two SR700 routers and the cloud server respectively, and the SR700 router within the network distance threshold range is used as the first priority transmission level, and the SR700 router not within the network distance threshold range is used as the first transmission level; in accordance with the above embodiment, if: after being processed by the network distance processing module, it is known that the gateway communication distance parameter between the first SR700 router and the cloud server is within the network distance threshold range, and the gateway communication distance parameter between the second SR700 router and the cloud server exceeds the network distance threshold range, the first SR700 router is used as the first priority transmission level, and the first SR700 router is used as the first transmission level; when network congestion occurs, the data and video required to be fed back by the first SR700 router as the first priority transmission level will be fed back to the cloud server first, and the second SR700 router as the first transmission level needs to wait for the first SR700 router to complete the feedback before feeding back the received oil field data and video to the cloud server.

[0072] The second priority setting module is used to take the oil well data or video received by each SR700 router as the first data set, and the oil well data or video received by each SR700 router as the second data set, and take the first data set in each SR700 router as the second priority transmission level, and take the second data set in each SR700 router as the second transmission level; in accordance with the above embodiment, such as: by obtaining the data reception status of each SR700 router, according to the first-come-first-served principle, when the first SR700 router receives the oil field data or video, it is divided into the first data set at the first time, and the first data set is divided into the second data set. The first SR700 router takes the first data set as the second priority transmission level, and gives priority to the feedback of the oilfield data or video received by the first SR700 router; when the transmission of the first data set is completed, the first SR700 router has received the next batch of oilfield data or video, then the batch of data is regarded as the second data set, and the second data set is transmitted after the transmission of the first data set is completed; the transmission mode of the second SR700 router is the same as the above description, which will not be repeated here; according to the above two transmission methods, not only the diversity of oil well data transmission is optimized, but also the blank waiting time caused by network congestion or different data feedback time is avoided, thereby improving the efficiency of oil well data transmission.

[0073] The cloud server is used to analyze and save the received oil well data and on-site videos, identify any abnormalities in a timely manner, and feedback to the client when abnormalities are found; the cloud server includes:

[0074] The data storage module is used to receive various data and on-site videos of the oil well site, and store the data and videos in time series to form an oil well database; specifically, various data and videos of the oil field are saved in time series, which is mainly convenient for later staff to check the required data and videos at any time according to date needs, and at the same time lays a solid data support for the development of the oil field.

[0075] The data encryption module is used to encrypt the oil well database using the AES symmetric encryption method. The client unlocks the oil well database according to the preset public key and obtains the access right to the oil well database. Specifically, by encrypting the oil well database using the AES symmetric encryption method, it not only provides powerful data protection capabilities, but also maintains high compatibility and scalability, limits the scope of data access, and improves data confidentiality.

[0076] The anti-tampering module is used to sign the oil well database using digital signature technology to prevent the oil well data from being maliciously tampered with; specifically, the data is signed through an encryption algorithm to ensure the integrity and authenticity of the data. The digital signature technology can be used to verify whether the data has been tampered with or forged, thereby protecting the source and integrity of the data.

[0077] The threshold setting module is used to collect multiple groups of temperature data, pressure data and liquid level data that meet normal conditions in oil field trial production, and adopt the intermediate value method to obtain the threshold of each data in the oil field trial production; specifically, the setting of the threshold is aimed at setting the safety limit of the oil well. Once certain key parameters exceed or fall below the preset threshold, the client will simultaneously issue a warning to ensure the safe operation of the oil well.

[0078] The abnormality judgment module is used to compare the various data of the current oil field with the corresponding thresholds, judge whether there are any abnormalities in the current data, and feed back to the client; specifically, by presetting the thresholds of the various data of the oil well, the current data is compared with the corresponding thresholds by using the comparison method. If a certain data is within the threshold range, it indicates that the current data is normal, that is, the corresponding oil well status is normal; if a certain data is not within the threshold range, it indicates that the current data is abnormal, that is, the corresponding oil well status is abnormal, and the abnormal signal of the data can be fed back to the client.

[0079] The client is a monitoring platform associated with the oil well site, which is used to display various data and on-site videos of the oil well site and abnormal conditions of the oil well site in real time; the client includes:

[0080] The data display terminal is a display screen used to display various data and on-site videos of the oil well site in real time, so that the staff can obtain and understand the operation status of the oil well test production in real time according to the display screen;

[0081] The alarm prompt unit is a buzzer, which is used to promptly send out an alarm sound through the buzzer when any data is in an abnormal situation; specifically, when an abnormal feedback is issued by the abnormal judgment module, an alarm is immediately issued through the buzzer, and the abnormal data is fed back to the display screen for display, so as to help the staff to understand the location of the abnormal situation and its related factors in a timely manner.

[0082] The present invention provides a data transmission method for an oilfield single well production test system, comprising the following steps:

[0083] S1, collect temperature data, pressure data, liquid level data and shoot on-site video of the oil field in real time through the data acquisition unit and video monitoring unit, and configure an SR700 router for each of the above two units;

[0084] S2. During transmission, if the network is congested, the gateway communication distance parameters of the two SR700 routers are determined, and the SR700 router within the network distance threshold range is given the first priority transmission level, and the data and video required to be fed back by the SR700 router are transmitted to the cloud server first;

[0085] S3. During transmission, if data feedback is not synchronized, the first data set received by each SR700 router is obtained, which is regarded as the second priority transmission level, and the data and video required to be fed back by the SR700 router are transmitted to the cloud server in priority;

[0086] S4. After receiving the data, the cloud server saves the data and videos, and further encrypts and tamper-proofs them to form an oil well database.

[0087] S5. Compare various oil field data with the threshold value to make abnormal judgment. If there is any abnormal situation, an alarm feedback will be given to the client in time. The client will send an alarm sound through a buzzer, thereby reminding the operator to check the abnormal factors of the oil field in time.

[0088] The beneficial effects achieved by the above content are as follows: Through the above method, the diversity of oil well data transmission is optimized, and the blank waiting time caused by network congestion or inconsistent data feedback time is avoided, thereby improving the efficiency of oil well data transmission; at the same time, the oil well database is encrypted and tamper-proofed to ensure the confidentiality and security of the oil well data, thereby improving the practicality of the data transmission device.

[0089] Working principle: By presetting the first and second priority transmission levels in advance according to the network distance communication parameters and data feedback timeliness, if the network is congested, the data and video that need to be fed back by the SR700 routers within the network distance threshold range will be transmitted to the cloud server first; if the data feedback is not synchronized, the first data set received by each SR700 router will be regarded as the second priority transmission level, and the first data set that the SR700 router needs to feedback will be transmitted to the cloud server first; otherwise, the subsequent data or video will continue to be fed back after the current SR700 router feedback ends.
