Description

Technical Field

[0001] The present invention relates to the field of offshore oil operation monitoring, and in particular to an offshore oil operation monitoring system and method based on visual recognition. Background Art

[0002] Offshore oil operations are related to national economic security and energy security. Due to the complex and changeable operating environment, offshore oil operations face great challenges and risks. In daily production, once there is a blowout, fire and explosion, platform distress, oil (gas) production facilities and pipeline damage / leakage, toxic and hazardous substance leakage, radioactive material escape; serious injury, death, disappearance, poisoning; oil spill accidents, natural disasters and other special circumstances, it will not only bring huge property losses, but also seriously threaten the personal safety of offshore workers. In order to effectively ensure the safety and stability of offshore oil operations, the offshore oil operation monitoring system has gradually become one of the essential tools for offshore oil operations. The offshore oil operation monitoring system realizes remote real-time monitoring of the production process and equipment facilities through sensors installed at various key nodes of the operation site. This monitoring system can help enterprise managers understand the production situation in real time, discover and solve problems in a timely manner, and improve production efficiency and safety.

[0003] The offshore oil operation monitoring system can realize real-time monitoring of the production process and equipment facilities based on the data information collected by the sensors, helping enterprise managers or production personnel to detect abnormal situations in time. The current offshore oil operation monitoring system faces at least one of the following problems: First, the existing technology often compares the data collected by a single sensor or the average value of the data collected by multiple sensors with the preset threshold to realize abnormal diagnosis. Its abnormal judgment method is relatively simple. This method is difficult to take into account the accurate monitoring of severe abnormalities in a small range and moderate abnormalities in a large range, and there are omissions or false alarms; for example, in a smaller working range, when there is a single sensor point data that is too high, if the abnormal diagnosis is realized based on the average value of the data collected by multiple sensors, there is a possibility of omission; in a larger working range, when there are multiple point sensor data that are high at the same time but have not reached a certain level, if the abnormal diagnosis is realized based on the data collected by a single sensor, there is also a possibility of omission; secondly, the sensor will produce accuracy drift and acquisition errors as the working time increases, especially In a complex operating environment, this precision drift and acquisition error will be more obvious, but accurate data collection based on sensors is the basis for accurate monitoring of the production process and equipment and facility status. How to accurately verify the reliability of sensors and achieve efficient operation and maintenance is a powerful measure to reduce operation and maintenance costs and improve operation and maintenance efficiency. In addition, increasing the density of sensor deployment is an effective measure to achieve accurate positioning of abnormalities, but it will bring about problems of excessive cost or installation difficulty. How to coordinate the deployment cost of sensors, installation difficulty and accurate positioning of abnormalities is a technical problem that needs to be solved urgently. Finally, in the process of inspecting the production process and equipment and facilities using unmanned automatic inspection equipment or manual inspection, in the face of a complex working environment, how to ensure the safety of personnel, unmanned automatic inspection equipment and production equipment and facilities is of great significance to ensuring safe production and reducing production costs.

The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] like Figure 1 As shown, the present invention is a method for monitoring offshore oil operations based on visual recognition, comprising the following steps:

[0051] S1: using different types of sensors to collect input and output data of each device and / or component, data of intermediate facilities, and data related to the surrounding environment; data related to the surrounding environment refers to data collected by sensors related to the environment, such as external wind speed, temperature, etc., which can also be called data related to the environment;

[0052] S2: Counting a first number of sensors of the same type whose collected data exceeds a first threshold, and a second number of sensors of the same type whose collected data exceeds a second threshold, wherein the first threshold is less than the second threshold;

[0053] S3: When the first number is greater than the first preset number or the second number is greater than the second preset number, it is preliminarily determined that an abnormality exists at the corresponding position, and the first preset number is greater than the second preset number;

[0054] The first preset number refers to the preset threshold of the number of sensors whose real-time collected data meets the condition of exceeding the first threshold, and the specific type is the number of sensors; the second preset number refers to the preset threshold of the number of sensors whose real-time collected data meets the condition of exceeding the second threshold, and the specific type is the number of sensors;

[0055] S4: Review and locate the abnormality based on the input, theoretical output data and actual output data of the equipment and / or components, and determine the corresponding position of the abnormality;

[0056] S5: Analyze and process the data information collected by different types of sensors, and automatically generate and adjust the production parameters of equipment and / or components in the production process based on the abnormal conditions and the corresponding positions of the abnormalities;

[0057] S6: mobilize automatic inspection equipment to conduct emergency inspection and maintenance of abnormal locations;

[0058] S7: When the abnormal situation is serious, a manual operation and maintenance work order is generated, and the automatic inspection equipment and operation and maintenance personnel work together to carry out abnormal situation detection and operation and maintenance operations.

[0059] In the description of the present invention, it is to be understood that the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the feature. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0060] In step S1, the offshore oil operation system includes multiple integrated modules of different functional links, and the device is an integrated module of a functional link in the offshore oil operation system. Therefore, multiple integrated modules correspond to multiple devices, and integrated modules with different functions correspond to different devices, such as underwater Christmas trees, underwater manifolds, water injection risers, oil risers, wellhead platforms, etc., and each device is connected in sequence through pipelines or corresponding fixed structures; each device is composed of different components, such as Figure 2 As shown, the underwater Christmas tree includes a Christmas tree cap, a top blocker, a tubing hanger, a valve group, an H4 connector, a wellhead and other components; the wellhead platform includes a base, a deck and columns and other components; this is only an example, and other equipment and corresponding components may also be included, which is not limited here.

[0061] The different types of sensors may be temperature sensors, pressure sensors, flow sensors, oil and gas concentration sensors, etc., which are arranged at the input and output positions of each device or component to collect the input and output parameters of each device or component; they may also be wind speed sensors, vibration frequency sensors, stress sensors, corrosion level sensors, which are arranged at the location of the corresponding facilities to collect the external wind speed, the vibration frequency of the equipment or platform, the stress magnitude, the corrosion degree, etc.; this is only an example, and other types of sensors may also be included according to the actual content to be monitored, which is not limited here;

[0062] When conducting offshore oil operations, abnormal situations are inevitable. The abnormal situations may be oil and gas leakage, pressure loss, etc. caused by cracks and gaps in the pipeline, or flow rate obstruction caused by corrosion. When an abnormal situation occurs, the parameter information collected by a few sensors in a small range may fluctuate greatly, or the parameter information collected by most sensors in a large range may fluctuate slightly. Traditional abnormality detection methods are difficult to accurately detect the two. To this end, the present invention proposes the following technical solutions:

[0063] Specifically, step S2 includes, at the same time or in the same time period, counting the number of data collected by the same type of sensors exceeding the first threshold as the first number; counting the number of data collected by the same type of sensors exceeding the second threshold as the second number; exceeding the first threshold corresponds to a smaller parameter information fluctuation; exceeding the second threshold corresponds to a larger parameter information fluctuation.

[0064] Correspondingly, in step S3, the first number is greater than the first preset number, corresponding to a relatively small range where the parameter information collected by a small number of sensors has undergone a large fluctuation; the second number is greater than the second preset number, corresponding to a relatively large range where the parameter information collected by a large number of sensors has undergone a small fluctuation; through the above method, the comprehensiveness and accuracy of anomaly detection can be improved;

[0065] The second preset number is greater than or equal to 1;

[0066] In one embodiment, the second preset number is 1; in this case, an abnormality review may be performed based on subsequent steps S4-S7;

[0067] In another embodiment, the second preset number is 2; at this time, the preliminary judgment that there is an abnormality at the corresponding position includes: mutual verification of the abnormal state between the two sensors, when the fluctuation of the data of the two sensors is consistent, it is preliminarily judged that there is an abnormality at the corresponding position; otherwise, it is judged as a false alarm, and suspected fault marks are added to the two sensors, and the automatic inspection equipment is mobilized to confirm it later;

[0068] In another embodiment, the second preset number is 3; at this time, the preliminary judgment that there is an abnormality at the corresponding position includes: mutual verification of abnormal states between different sensors, and when the fluctuations of at least two sensor data are consistent, it is preliminarily judged that there is an abnormality at the corresponding position; otherwise, it is judged as a false alarm, and a suspected fault mark is added to the sensor whose fluctuation is inconsistent with that of most sensors, and the automatic inspection equipment is mobilized to confirm it later;

[0069] Optionally, the second preset number may be greater than 3; in this case, the preliminary determination of the presence of an abnormality at the corresponding position is similar to the corresponding process when the second preset number is 3.

[0070] Through the above technical scheme, the present invention can avoid the omission and false detection caused by the single abnormality judgment method and sensor error to a certain extent, so that the accuracy of abnormality detection has been significantly improved, but how to further improve the accuracy of abnormality detection and how to quickly locate the abnormal position are still of great significance; generally speaking, increasing the density of sensor layout is an effective measure to achieve accurate positioning of abnormalities, but it will bring about the problem of excessive cost or installation difficulty. How to coordinate the accuracy of abnormality detection, the layout cost of sensors, the difficulty of installation and the accurate positioning of abnormalities are technical problems that need to be solved in this field; for this reason, the present invention proposes the following technical scheme:

[0071] The offshore oil operation system includes different equipment, each of which is connected in sequence; each equipment is composed of different components, each of which is also connected in sequence; different equipment and components correspond to different transfer function models, and the theoretical output value of the equipment or component can be determined based on the input parameters of the equipment or component and the transfer function model, for example, the theoretical output value of equipment m = input parameters of equipment m / (transfer function model of equipment m);

[0072] The step S4 comprises:

[0073] S41: collecting input and output parameters of each device and / or component using sensors arranged at input and output positions of each device and / or component;

[0074] S42: Determine the input parameters of each device, and input them into the transfer function model corresponding to each device to obtain the theoretical output value of the device;

[0075] S43: taking the collected output parameters of each device as the actual output value of the device, and comparing the theoretical output value and the actual output value of each device;

[0076] S44: when the difference between the theoretical output value and the actual output value of the device is greater than a preset value, a review result is obtained, the device is determined to be abnormal, and the abnormal device location information is output; otherwise, it is determined to be a false alarm;

[0077] S45: determining whether the abnormal device includes a component, and if so, further determining the location information of the abnormal component;

[0078] S46: Determine the input parameters of each component, and input them into the transfer function model corresponding to each component to obtain the theoretical output value of the component;

[0079] S47: taking the collected output parameters of each component as the actual output value of the component, and comparing the theoretical output value and the actual output value of each component;

[0080] S48: When the difference between the theoretical output value and the actual output value of the component is greater than a preset value, a review result is obtained, the component is determined to be abnormal, and the abnormal component position information is output.

[0081] Among them, in the step S42, the input parameters of each device can be: the input parameters of each device collected by the sensor in real time; for example, the offshore oil operation system includes three devices, namely device 1, device 2, and device 3, and the parameters collected in real time by the sensors respectively arranged at the input positions of device 1, device 2, and device 3 are used as the input parameters of device 1, device 2, and device 3 to calculate the theoretical output value of the device; the use of this method to calculate the theoretical output value of each device can avoid the accumulation of reasonable errors of each device itself, and realize accurate monitoring of the working status of each device;

[0082] Optionally, the input parameters of each device may also be: using the data collected by the sensor set at the input position of the first device as the input parameter of the first device, and using the theoretical output value of the device calculated by the first device input parameter and the transfer function model corresponding to each device as the input parameter of the next-level device; for example, the offshore oil operation system includes three devices, namely device 1, device 2, and device 3, and the three devices are connected in sequence, using the parameters collected in real time by the sensor set at the input position of device 1 as the input parameter of device 1, using the input parameters of device 1 and the transfer function model of device 1 to calculate the theoretical output value of device 1, and using the theoretical output value of device 1 as the input parameter of device 2, and subsequently using the theoretical output value of device 2 as the input parameter of device 3, to calculate the theoretical output value of the device; using this method to calculate the theoretical output value of each device can realize the monitoring of the overall state of the system; when using this method to calculate the theoretical output value of the device, it also includes:

[0083] When the difference between the theoretical output value and the actual output value of a certain level of equipment is within a first preset range, all equipment before the equipment of this level is subject to minor overhaul; when the difference between the theoretical output value and the actual output value of a certain level of equipment is within a second preset range, all equipment before the equipment of this level is subject to major overhaul; compared with the first preset range, the second preset range indicates that the overall error of the system is greater;

[0084] Similarly, in S46, the input parameters of each component may also be the two methods in S42; similar to the above scheme, a major overhaul or a minor overhaul of the system may also be performed based on the difference between the theoretical output value and the actual output value of a certain level of component;

[0085] The present invention can realize fast and accurate positioning of abnormalities while improving the accuracy of abnormality detection and reducing the cost and difficulty of sensor deployment through two-level review and positioning of equipment and components.

[0086] The step S5 comprises:

[0087] S51: preprocessing and feature extraction of the collected input and output data of each device and / or component, data of other intermediate facilities, and data related to the surrounding environment to obtain a feature vector;

[0088] S52: Acquire the abnormal situation and the position corresponding to the abnormal situation, input the abnormal situation, the position corresponding to the abnormal situation and the characteristic vector into the preset control model, and the preset control module automatically generates and adjusts the production parameters of each device and / or component accordingly.

[0089] The preset control model is obtained by training based on production data in the trial production stage; the production parameters of each device and / or component may be the opening and closing size of the valve, the suction size of the motor, etc.;

[0090] Optionally, also include:

[0091] S53: Obtain wind speed and earthquake warning data. When the wind speed exceeds a preset value or there is an earthquake warning higher than a preset level, stop production operations, call the automatic inspection equipment to return to the docking cabin, and start the locker to close the oil outlet;

[0092] S54: Obtain deformation magnitude, vibration frequency and stress data at key positions of equipment and / or components, determine the severity of the abnormality in combination with the wind speed, and inject seawater into a preset container based on the severity of the abnormality;

[0093] The deformation size is obtained based on the visual recognition module; the vibration frequency and stress data are obtained based on the corresponding sensors;

[0094] The method of determining the severity of the abnormality in combination with the wind speed and injecting seawater into a preset container based on the severity of the abnormality includes:

[0095] S541: Calculate the severity of the abnormality M=f(w, x, y, z), where f represents a preset function, w represents the deformation size, x represents the vibration frequency, y represents the stress data, and z represents the wind speed;

[0096] S542: Determine the height of the water level in the preset container based on the severity of the abnormality, H=k×M, where k is a preset proportionality coefficient;

[0097] S543: Add the water level to H;

[0098] The preset container refers to a buoyancy box fixed on an offshore oil operating platform; by filling the buoy with water to a preset height, the weight of the platform can be increased, thereby reducing the impact of severe weather such as strong winds, heavy rains and earthquakes.

[0099] The present invention can comprehensively consider equipment information, environmental information, and abnormal status information, and reasonably control the single well production according to the actual situation on site, and take measures to increase and stabilize production in a timely manner, so as to maximize the production safety and oil and gas recovery efficiency of the oil and gas field and avoid property losses.
