Description

Technical Field

[0001] The present invention relates to the field of research and development of detection equipment in oil and gas pipelines and detection technology, and in particular to a method and system for identifying and responding to ball stoppage in detection equipment in oil and gas pipelines. Background Art

[0002] When the oil and gas pipeline inspection equipment is performing inspection tasks in the oil and gas pipeline, it may stop moving forward for some reason, which we call "stopping the ball". There are many possible reasons for stopping the ball, including but not limited to the following:

[0003] 1. When passing a bend, you may hold the pressure to stop the ball for a short time, or you may stop the ball for a long time;

[0004] 2. Valve obstruction: When the valve is not opened or not fully opened, the internal detection equipment may be blocked, resulting in ball stoppage;

[0005] 3. The three-way pipe is blocked. When the three-way pipe is not blocked in time, the internal detection equipment may deviate from the direction, causing it to be blocked at the three-way, and eventually causing the ball to stop;

[0006] 4. The leather cup is damaged. When the leather cup is severely damaged, the pushing pressure on the internal detection device is insufficient, making the detection device unable to move forward and eventually stop the ball;

[0007] 5. The medium stops being transported. Since the internal inspection equipment needs to move forward with the help of the transported medium, when the medium stops being transported, the internal inspection equipment cannot move forward and eventually stops.

[0008] 6. Obstacles. Some oil and gas pipelines are not cleaned, or there are many impurities left after cleaning. As the internal inspection equipment moves forward, more and more impurities accumulate, forming obstacles, which prevent the internal inspection equipment from moving forward, resulting in a ball stop;

[0009] 7. Pipeline deformation. When the pipeline is severely deformed, the internal detection equipment will be stuck and unable to move forward, eventually stopping the ball;

[0010] 8. Insufficient pressure. When the medium pressure is insufficient, the internal detection equipment cannot move forward, resulting in ball stoppage.

[0011] 9. Other reasons not listed above lead to the suspension of play.

[0012] Since the reasons for stopping the ball are complex and the timing of many stops is difficult to predict, a fast and effective method is needed to determine whether the internal detection device is currently in a stopped state. When the internal detection device is in a stopped state, it is necessary to further analyze the reasons for the stop so that targeted stop measures can be taken. Based on historical data, through data fusion algorithms and self-developed AI data training models, various reasons for stopping the ball can be identified more accurately.

[0013] At present, no relevant literature has been found on the method for identifying and coping with the ball stop of the oil and gas pipeline detection equipment. The present invention is to effectively solve the problem of ball stop of the oil and gas pipeline detection equipment encountered in actual work, especially when the oil and gas pipeline detection equipment stops for a long time, the energy carried by the equipment is not enough to support the long-term stop, or when the oil and gas pipeline detection equipment moves forward again, the remaining energy carried by the internal detection equipment cannot support the oil and gas pipeline detection equipment to detect the remaining pipeline. As a result, the oil and gas pipeline detection task fails and needs to be re-detected, which doubles the detection cost.

[0014] In actual work, there is a special situation. When transporting oil or gas, pipeline inspection is carried out. Since each oil or gas transportation has only a specific time window, such as 10:00 am to 4:00 pm, each transportation lasts 6 hours. Since the pipeline is long, if the entire ball-passing time needs to last 24 hours. Therefore, only about 25% of the length of the oil and gas pipeline can be inspected in one oil or gas transportation. The next oil or gas transportation may be half a month later. Therefore, when the internal inspection equipment stops, it is necessary to detect the stop status, reasons, etc., and take corresponding countermeasures to ensure that there is enough energy to ensure the internal inspection equipment to perform the inspection task during the next oil or gas transportation.

[0015] Conventional internal detection equipment cannot work continuously for more than 15 days, and most internal detection equipment work for less than 7 days. However, the present invention can extend the working time of the internal detection equipment by identifying the ball stopping method and taking countermeasures, thereby completing the internal detection task. Summary of the invention

[0016] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a method and system for identifying and responding to ball stoppage of detection equipment in oil and gas pipelines, which can effectively solve the problem of detection task failure caused by long-term stoppage of the detection equipment in the pipeline.

[0017] In order to achieve the above object, the present invention is implemented through the following technical solution: a method for identifying and coping with ball stop in detection equipment in oil and gas pipelines, comprising the following steps:

[0018] 1. The coprocessor controls the pressure sensor, motion sensor, and mileage sensor to power on, stop working, and shut down at a regular interval.

[0019] 2. The coprocessor collects and saves the data transmitted by the pressure sensor, motion sensor, and mileage sensor.

[0020] 3. The coprocessor preprocesses the data in step 2 through a self-developed digital filtering algorithm and saves it.

[0021] 4. The coprocessor processes the data in step 3 through a self-developed multi-source data fusion algorithm and saves it.

[0022] 5. The coprocessor sends the data in step 4 to the self-developed AI data training model for processing and saves the results.

[0023] 6. The coprocessor matches the model matching result of step 5 with the stop model. If it is recognized that the internal detection device is in the ball-stopping state, step 7 is executed; otherwise, step 1 is executed.

[0024] 7. The current internal detection equipment is in a stopped state. Through current data and historical data, further analysis and identification of the cause of the stoppage can be performed.

[0025] 8. The coprocessor gives a corresponding response method based on the reason for the ball stop identified in step 7.

[0026] A ball stop recognition and response system for detection equipment in oil and gas pipelines, including a coprocessor, wherein the coprocessor is respectively connected to a tail pressure sensor, a head pressure sensor, a motion sensor, a mileage sensor, a mainboard power supply, and a probe power supply, the mainboard power supply is also connected to a main processor, the probe power supply is connected to the probe, and the probe is connected to the main processor; the coprocessor runs in a low power consumption mode, collects the above sensor data, and performs parallel data calculation and analysis to determine which state the current device is in, thereby controlling the operating mode of the internal detection equipment.

[0027] Preferably, the tail pressure sensor and the head pressure sensor are respectively arranged at the front and rear positions of the internal detection device, and the tail pressure sensor and the head pressure sensor collect the pressure conditions of the pipeline.

[0028] Preferably, the motion sensor is used to determine the motion state of the internal detection device.

[0029] Preferably, the mileage sensor records the running mileage of the internal detection device, and the detected mileage data is used to calculate the running speed of the device to assist in determining whether the internal detection device is moving forward or stopped; when the internal detection device stops, the mileage position of the stop is calculated; when the gas-liquid medium stops being transported, the internal detection device will slowly stop, and after the set time, the internal detection device will enter a shutdown state and the probe will stop powering on, at which time the power consumption of the internal detection device is the lowest; of course, in other stopped states, the coprocessor will allow the internal detection device to enter an appropriate state based on the algorithm and data model.

[0030] Preferably, the mainboard power supply is responsible for supplying power to the main processor and is controlled by the coprocessor. When the coprocessor needs to control the main processor to shut down, the coprocessor sends an instruction to the mainboard power supply W1 to stop supplying power to the main processor, and the main processor will not work at all.

[0031] Preferably, the probe power supply is responsible for supplying power to the data acquisition probe of the internal detection device and is controlled by the coprocessor. When the coprocessor needs to control the probe to be powered off, the coprocessor sends an instruction to the probe power supply to stop supplying power to the probe, and the probe will not work at all when it is powered off.

[0032] Preferably, the main processor is mainly responsible for data collection and storage of a large number of probes, and maintains communication with the coprocessor, and accepts instructions from the coprocessor to enter a corresponding working state.

Different response methods can ensure that the internal detection device is in an optimal power consumption state. In particular, when the internal detection device is in a ball-stopping state for a long time, the internal detection device has only a very low detection power consumption, thereby ensuring that the internal detection device can experience multiple long-term ball-stopping states and still complete the detection task of the entire pipeline. Therefore, the present invention can effectively solve the problem of detection task failure caused by the internal detection device being stopped for a long time in the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments;

[0037] Figure 1 It is the overall architecture diagram of the present invention. DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] Reference Figure 1, this specific implementation adopts the following technical solutions: a ball stop identification and response system for oil and gas pipeline internal detection equipment, including a coprocessor M1, the coprocessor M1 is respectively connected to the tail pressure sensor P1, the head pressure sensor P2, the motion sensor D, the mileage sensor S, the mainboard power supply W1, and the probe power supply W2, the mainboard power supply W1 is also connected to the main processor C1, the probe power supply W2 is connected to the probe, and the probe is connected to the main processor C1; the coprocessor M1 adopts an ultra-low power single-chip microcomputer, which can reach the mW level. The processor mainly runs in low-power mode, by collecting data from pressure sensors, motion sensors, mileage sensors, etc., parallel data calculation and analysis, to determine which state the current device is in, so as to control the operation mode of the internal detection equipment. For example, the internal detection is controlled to be shutdown, shutdown, sleep, start, etc.

[0040] It is worth noting that the tail pressure sensor P1 and the head pressure sensor P2 are respectively arranged at the front and rear positions of the internal detection device. The tail pressure sensor P1 and the head pressure sensor P2 collect the pressure conditions of the pipeline, such as whether it is increasing pressure, decreasing pressure, or holding pressure. Combined with other sensor data, it is determined whether the internal detection device is entering the pipeline, exiting the pipeline, or holding pressure in the pipeline, or is blocked. When the device stops due to holding pressure, or stops due to a stuck ball, the internal detection device handles it according to the set response method.

[0041] It is worth noting that the motion sensor D is used to determine the motion state of the internal detection device. For example, when the internal detection device is stationary, it can be combined with other data to identify the ball jam, ball stop, ball entering the ball collection tube, ball launching tube, etc., and after a certain period of time, the internal detection device can enter the operation mode set by the program. For example, when the internal detection device stops due to the stop of medium transmission, the internal detection device enters the lowest power consumption state. Only the coprocessor M1 of the internal detection device works in a low power consumption state. At this time, the internal detection device can be used for more than ten days or even months. The specific duration depends on the battery capacity of the internal detection device.

[0042] It is worth noting that the mileage sensor S records the running mileage of the internal detection device. The detected mileage data is used to calculate the running speed of the device to assist in judging whether the internal detection device is moving forward or stopped. When the internal detection device stops, the mileage position of the stop is calculated. When the gas-liquid medium stops being transported, the internal detection device will slowly stop. After the set time, the internal detection device will enter a shutdown state and the probe will stop powering on. At this time, the power consumption of the internal detection device is the lowest. Of course, in other stop states, the coprocessor will allow the internal detection device to enter an appropriate state based on the algorithm and data model.

[0043] It is worth noting that the mainboard power supply W1 is responsible for supplying power to the main processor C1 and is controlled by the coprocessor M1. When the coprocessor M1 needs to control the main processor C1 to shut down, the coprocessor M1 sends a command to the mainboard power supply W1 to stop supplying power to the main processor C1, and the main processor C1 will not work at all.

[0044] It is worth noting that the probe power supply W2 is responsible for supplying power to the data acquisition probe of the internal detection device and is controlled by the coprocessor M1. When the coprocessor M1 needs to control the probe to be powered off, the coprocessor M1 sends an instruction to the probe power supply W2 to stop supplying power to the probe. At this time, the probe will not work at all.

[0045] It is worth noting that the main processor C1 is mainly responsible for data collection and storage of a large number of probes, and maintains communication with the coprocessor M1, and receives instructions from the coprocessor M1 to enter the corresponding working state, such as startup, sleep, deep sleep, shutdown preparation, etc.

[0046] In addition, the probe is a sensor set used by the internal detection equipment to collect various pipeline data.

[0047] The coprocessor M1 of this specific implementation method controls various sensors and collects data, and combines historical data, uses a multi-source data fusion algorithm, and adds a self-developed AI data training model to determine the current operating status of the internal detection device. The most important thing is to identify whether the internal detection device is in a stopped state. If the internal detection device is in a stopped state, it is necessary to further identify the reason for the stop of the internal detection device. According to the reasons for the stop identified and analyzed, a corresponding identification method is given.

[0048] A method for identifying and responding to ball stoppage in detection equipment in oil and gas pipelines, comprising the following steps:

[0049] 1. The coprocessor M1 regularly controls the power-on, power-off and shutdown states of the pressure sensor, motion sensor and mileage sensor.

[0050] 2. Coprocessor M1 collects and saves data transmitted by pressure sensor, motion sensor, and mileage sensor.

[0051] 3. Coprocessor M1 preprocesses the data in step 2 through a self-developed digital filtering algorithm and saves it.

[0052] 4. Coprocessor M1 processes the data in step 3 through a self-developed multi-source data fusion algorithm and saves it.

[0053] 5. Coprocessor M1 sends the data in step 4 to the self-developed AI data training model for processing and saves the results.

[0054] 6. The coprocessor M1 matches the model matching result of step 5 with the stop model. If it is identified that the internal detection device is in the ball-stopping state, step 7 is executed; otherwise, step 1 is executed.

[0055] 7. The current internal detection equipment is in a stopped state. Through current data and historical data, further analysis and identification of the cause of the stoppage can be performed.

[0056] 8. Coprocessor M1 gives a corresponding response method based on the reason for the ball stop identified in step 7.

[0057] The following are some implementation cases of the corresponding treatment methods:

[0058] Example 1: When the internal detection device enters the ball collecting cylinder, the pressure sensor P1-P2 < the pressure difference setting value, the motion sensor D detects that the internal detection device is stationary, the mileage sensor > the set mileage, and the timer > the set duration. At this time, the coprocessor M1 turns off the main power W1 and the probe power W2, and all the equipment is automatically powered off and enters the shutdown state. Manual restart of the internal detection device is required.

[0059] Example 2: When the ball is stuck in the internal detection device, the pressure sensor P1-P2> the pressure difference setting value, the motion sensor D detects that the internal detection device is stationary, the planned mileage> the mileage sensor> the set mileage, and the timer> the set duration. At this time, the coprocessor M1 turns off the main power W1 and the probe power W2, and the internal detection device enters the shutdown state.

[0060] Example 3: When the medium of the internal detection device stops being transported, the pressure sensor P1-P2 < the pressure difference setting value, the motion sensor D detects that the internal detection device is stationary, the planned mileage > the mileage sensor > the set mileage, and the timer > the set duration. At this time, the coprocessor M1 turns off the main power W1 and the probe power W2, and the internal detection device enters the shutdown state.

[0061] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
