[0044] High temperature and high pressure visual pressure chamber 110, foam sensor device 120, differential pressure transmitter 130, pressure controller 140, electronic control system 150 and computing center 160;

[0045] Among them, Figure 2 As shown, the high-temperature and high-pressure visual pressure chamber 110 can be made of high-temperature and high-pressure resistant materials, and includes an upper plug 1, a sampler body 2, a visual window cover 3, a pressure chamber visual window 4, and a lower plug 5. Here, the foam to be detected can enter the foam carrying container 6 of the sampler body 2 from the upper plug 1 or the lower plug 5; the sampler body 2 is used to heat the foam to be detected based on the temperature control instruction issued by the electronic control system 150; the visual window cover 3 is used to display or hide the pressure chamber visual window 4; the pressure chamber visual window 4 is a visual window with a scale, which is used to observe the foam to be detected in the sampler body 2, and it can be a sapphire window;

[0046] The differential pressure transmitter 130 is used to measure the pressure in the high temperature and high pressure visible pressure chamber 110;

[0047] The pressure controller 140 is used to control the pressure in the high-temperature and high-pressure visible pressure chamber 110 based on the pressure control instruction issued by the electronic control system 150 and the detection result of the differential pressure transmitter 130;

[0048] The foam sensor device 120 is used to detect the foam height of the foam to be detected;

[0049] The computing center 160 is used to determine the liquid separation half-life of the foam to be detected when the foam sensor device 120 detects that the real-time foam height of the foam to be detected reaches a preset value.

[0050] In some embodiments, the foam sensing device 120 includes an industrial camera; the real-time foam height of the foam to be detected is obtained by performing foam boundary recognition and scale line recognition on the foam image with scale taken by the industrial camera on the pressure chamber visual window 4. The industrial camera is connected to a movable track, and the industrial camera can slide up and down along the movable track under the control of the electronic control system 150.

[0051] In other embodiments, the foam sensing device 120 includes a displacement sensor.

[0052] According to the device provided by the embodiment of the present invention, the reservoir foam can be injected into a high-temperature and high-pressure visual pressure chamber that is resistant to high temperature and high pressure. Under the control of the electronic control system, the reservoir foam can be controlled at any pressure and temperature based on the differential pressure transmitter, the pressure controller and the sampler body of the high-temperature and high-pressure visual pressure chamber to simulate the foam attenuation under high temperature and high pressure, and the liquid separation half-life of the reservoir foam can be automatically determined based on the real-time detection of the foam height through the foam sensor device and the computing center.

[0053] The detection test method provided by the present invention is described below. The detection test method described below and the high-temperature and high-pressure foam detection test device described above can be referenced to each other.

[0054] Based on any of the above embodiments, Figure 3 Schematic diagram of the flow of the detection test method provided by the present invention, which is used to simulate the foam decay and determine the liquid separation half-life of the reservoir foam based on the high temperature and high pressure foam detection test device. Figure 3 As shown, the method includes:

[0055] Step 310, controlling the foam to be detected to enter the sampler body from the upper plug or the lower plug of the high-temperature and high-pressure visual pressure chamber, and sending temperature control instructions and pressure control instructions to the sampler body and the pressure controller respectively based on the electronic control system, so that the sampler body heats the foam to be detected based on the temperature control instructions sent by the electronic control system, and the pressure controller controls the pressure in the high-temperature and high-pressure visual pressure chamber based on the pressure control instructions sent by the electronic control system and the detection result of the differential pressure transmitter;

[0056] Step 320, based on the computing center, the real-time foam height of the foam to be detected detected by the foam sensing device is obtained, and when the real-time foam height of the foam to be detected reaches a preset value, the liquid separation half-life of the foam to be detected is determined.

[0057] Specifically, after the foam to be tested is injected into the sampler body from the upper plug or the lower plug of the high-temperature and high-pressure visual pressure chamber, the electronic control system is used to send temperature control instructions and pressure control instructions to the sampler body and the pressure controller respectively, so that on the one hand, the heating rod in the sampler body can heat the foam to be tested based on the temperature control instruction issued by the electronic control system, and heat its temperature to a preset temperature value; on the other hand, the pressure controller can control the pressure in the high-temperature and high-pressure visual pressure chamber based on the pressure control instruction issued by the electronic control system and the real-time pressure detection results fed back by the differential pressure transmitter, and control the pressure in the chamber to a preset pressure value.

[0058] Subsequently, the real-time foam height during the attenuation process of the foam to be detected can be monitored in real time based on the foam sensing device, and the liquid precipitation half-life of the foam to be detected can be determined when the real-time foam height of the foam to be detected reaches a preset value (for example, half of the initial value of the foam height after the foam to be detected is injected into the high-temperature and high-pressure visual pressure chamber and the temperature and pressure in the chamber are stabilized). Here, the time when the real-time foam height of the foam to be detected reaches the preset value can be determined, and the time difference between the initial time after the foam to be detected is injected into the high-temperature and high-pressure visual pressure chamber and the temperature and pressure in the chamber are stabilized and the time when the real-time foam height reaches the preset value can be determined as the liquid precipitation half-life of the foam to be detected.

[0059] In some embodiments, when the foam sensing device includes an industrial camera, in order to obtain the real-time foam height of the foam to be detected in real time, the current scaled foam image taken by the industrial camera on the visual window of the pressure chamber in real time can be obtained. In some embodiments, considering that the shooting angle will affect the scale reading, in order to take a more accurate scaled foam image to more accurately determine the real-time foam height, the position of the industrial camera can be adjusted based on the foam height drop rate and the shooting time of the previous scaled foam image, so that the industrial camera is as flush with the current foam interface as possible, and the pressure chamber visual window is photographed based on the adjusted industrial camera to obtain the current scaled foam image. Among them, the foam height drop speed is determined based on the historical foam height within a preset time period. For example, based on the historical foam height obtained at each time point within the preset time period, the average of the drop speeds of the historical foam heights at two adjacent time points can be obtained as the above-mentioned foam height drop speed. Subsequently, the scale line recognition of the current scaled foam image can be performed using a pre-set scale line pattern based on pattern recognition technology to obtain the position of each scale line in the current scaled foam image.

[0060] In addition, the current scaled foam image can also be subjected to foam boundary recognition based on the foam boundary recognition model to obtain the foam boundary position in the current scaled foam image. In some embodiments, in order to improve the accuracy of foam boundary recognition, a foam boundary recognition model including a foam boundary prediction branch and a foam area prediction branch can be constructed. Among them, the foam boundary prediction branch and the foam area prediction branch can both be constructed based on the encoder-decoder model, and the foam boundary prediction branch and the foam area prediction branch share an encoder. Here, the reason for introducing the foam area prediction branch is that a large amount of foam aggregation will affect the recognition of the boundary, and the scale lines in the image will also interfere with the recognition. The introduction of the foam area prediction branch can effectively utilize the shape features of the foam area, assist in determining the position of the foam boundary, and improve the accuracy of foam boundary recognition. It should be noted that the foam area prediction branch only exists in the training stage of the foam boundary recognition model, and the branch can be removed in the actual application stage.

[0061] In the training phase of the foam boundary recognition model, multiple sample scaled foam images can be collected and the sample scaled foam images can be annotated with foam boundaries and foam regions to obtain an annotated foam boundary map and an annotated region map of the corresponding sample scaled foam image. For any sample scaled foam image, the sample scaled foam image can be predicted based on the foam boundary prediction branch and the foam region prediction branch in the foam boundary recognition model to obtain a foam boundary map and a foam region map of the sample scaled foam image. The foam boundary map indicates the foam boundary position in the sample scaled foam image predicted by the model, and the pixel points corresponding to the foam boundary in the sample scaled foam image have a value of 1 in the foam boundary map; the foam region map indicates the foam region in the sample scaled foam image predicted by the model, and the pixel points corresponding to the foam region in the sample scaled foam image have a value of 1 in the foam region map.

[0062] Based on the matching degree between the above-mentioned foam boundary map and the foam area map, the auxiliary matching loss can be determined. Here, the boundary distance map of the sample scaled foam image can be determined based on the foam area (i.e., foreground area) indicated in the foam area map and the area outside the foam area (i.e., background area). Among them, the boundary distance map indicates the distance of each pixel from the upper boundary of the foam area map. The closer any foreground pixel or any background pixel is to the upper boundary, the smaller the value of the foreground pixel or the background pixel in the boundary distance map. Subsequently, the foam boundary map and the above-mentioned boundary distance map are dot-multiplied pixel by pixel to obtain a boundary matching map, and the boundary matching map is accumulated pixel by pixel to obtain the auxiliary matching loss. Next, based on the difference between the foam boundary map and the annotated foam boundary map, the difference between the foam area map and the annotated area map, and the auxiliary matching loss, the parameters of the foam boundary recognition model are updated to complete a round of training of the foam boundary recognition model. Repeat the above operation for each sample scaled foam image to obtain a trained foam boundary recognition model.

[0063] Based on the above-mentioned foam boundary position and the position of each scale line, the real-time foam height of the foam to be detected can be determined. Among them, the scale value corresponding to the scale line closest to the foam boundary position can be determined as the real-time foam height of the foam to be detected. In some embodiments, since the foam itself has different shapes and sizes and there is foam aggregation, the foam boundary position predicted by the model may not be flush. Therefore, in order to determine the real-time foam height of the foam to be detected, a linear fit can be performed on the foam boundary position based on the coordinates of each point in the foam boundary position. After finding a straight line closest to the foam boundary position, the distance between the straight line and each scale line is calculated, so as to determine the scale value corresponding to the scale line closest to the straight line as the real-time foam height of the foam to be detected.

[0064] The detection test method provided by the embodiment of the present invention controls the foam to be detected to enter the sampler body from the upper plug or the lower plug of the high-temperature and high-pressure visual pressure chamber, and sends temperature control instructions and pressure control instructions to the sampler body and the pressure controller respectively based on the electronic control system, so that the sampler body heats the foam to be detected based on the temperature control instruction issued by the electronic control system, and the pressure controller controls the pressure in the high-temperature and high-pressure visual pressure chamber based on the pressure control instruction issued by the electronic control system and the detection result of the differential pressure transmitter. Subsequently, the real-time foam height of the foam to be detected obtained by the foam sensing device combined with the corresponding foam height acquisition algorithm is obtained based on the computing center, and the liquid separation half-life of the foam to be detected is determined when the real-time foam height of the foam to be detected reaches a preset value, so that the liquid separation half-life of the foam to be detected can be automatically and accurately obtained.
