It should be further noted that the terms "first," "second," and the like in the description and in the drawings are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order, or importance.
Referring to fig. 1, fig. 1 is a flow chart of an embodiment of a method for monitoring returned cuttings from a well, where the method includes:
101. the terminal obtains a scanning result of the laser radar on the outlet of the vibrating screen, and obtains video stream data obtained by shooting rock debris on the outlet of the vibrating screen by the camera;
102. the terminal generates 3D point cloud data according to the scanning result;
in this embodiment, a lidar is used to scan the debris conditions at the exit of the shaker. After the terminal issues the monitoring instruction, the laser radar starts to execute the scanning modeling task at a fixed rate of 5 times per second. After the scanning result is obtained, the scanning result is transmitted to the terminal, and the terminal continuously generates 3D point cloud data according to the scanning result.
The image pickup device is used for shooting the whole condition of the vibrating screen outlet. After the terminal issues a shooting instruction, the shooting device shoots. The frame rate of the acquired video stream data may generally be up to 30 frames per second, with 10 frames per second being taken for calculation in this embodiment.
The laser radar can scan to obtain original three-dimensional data, so that the data has depth information, and real rock debris conditions are digitized in more detail and accurately, thereby facilitating subsequent processing on a terminal. The camera equipment can be used for assisting the laser radar, video stream data and 3D cloud point data are combined, and data which are closer to the actual situation can be obtained more accurately.
103. The terminal calculates through the 3D point cloud data to obtain a first volume of rock debris;
in this embodiment, the terminal needs to process the 3D point cloud data. For example, firstly, carrying out plane segmentation on the 3D point cloud data, removing partial information with a vibrating screen as a plane, and highlighting a rock debris main body;
after carrying out plane segmentation on the 3D point cloud data, using an outlier algorithm on the data after plane segmentation to remove outlier noise points which are inconsistent in the periphery or the inside, increasing the calculation speed and enabling the data after plane segmentation to remove redundancy; then, using a clustering algorithm to enable the rock fragments to be piled up into the same cluster near the rock fragments, so that calculation is simplified;
and finally, calculating the volume of each cluster of rock debris piles respectively, constructing a convex hull according to the target point cloud, and obtaining rock debris volume data, namely the first volume.
104. The terminal calculates through the video stream data to obtain a second volume of rock debris;
in this embodiment, in order to assist the lidar in performing numerical adjustment on the monitoring data, binarization processing is required to be performed on the cuttings image in the video stream data, and the relevant threshold is dynamically adjusted, so that each video frame presents a corresponding result, and the result after the whole video stream data processing is the target dynamic model.
After the target dynamic model is obtained, the target objects containing the rock fragments are presented in a video frame and distributed in an irregular state, and then the calculation is carried out by using the method comprising segmentation and clustering (tightly connected rock fragment image piles are gathered to form a plurality of pile-shaped distributions), difference compensation (the image gathering piles are presented in a convex shape, partial concave compensation or partial large fluctuation edge smoothing and cutting are carried out), outlier removal and integration thought.
Let the first volume be X and the second volume be Y, a volume calculation function v=ax+by+β is constructed, where a, b, β are parameters that are continuously modified according to the monitored true values, so that the overall result tends to be true.

After the data processing is performed by using a plurality of methods, the rock debris volume, namely the second volume, in the target object of the video stream data can be calculated more clearly.
After the 3D point cloud data and the video stream data are further processed, the 3D point cloud data and the video stream data are intuitively closer to the true value by utilizing calculation and correction of the volume.
105. The terminal monitors rock debris conditions of the vibrating screen opening according to the first volume and the second volume.
The laser radar can generate rock debris 3D point cloud data with depth information, the imaging equipment can more accurately record the condition of the vibrating screen outlet, and meanwhile, the terminal is used for assisting in processing data, so that a discrimination warning system is established, and the rock debris condition can be monitored in real time. If abnormal conditions of rock debris are found, the terminal can give alarm information timely, and safety in drilling construction is improved.
In practice, the step of monitoring the condition of the rock debris at the vibrating screen opening by the terminal according to the first volume and the second volume requires further processing, and another embodiment is provided herein to explain this in detail:
referring to fig. 2, this embodiment includes:
201. the terminal obtains a scanning result of the laser radar on the outlet of the vibrating screen, and obtains video stream data obtained by shooting rock debris on the outlet of the vibrating screen by the camera;
202. the terminal generates 3D point cloud data according to the scanning result;
203. the terminal calculates through the 3D point cloud data to obtain a first volume of rock debris;
204. the terminal calculates through the video stream data to obtain a second volume of rock debris;
steps 201 to 204 in this embodiment are similar to steps 101 to 104 in the embodiment shown in fig. 1, and are not repeated here.
205. The terminal generates target rock debris monitoring data according to the first volume and the second volume;
in this embodiment, the terminal first performs a difference average calculation on the first volume and the second volume, and then combines the data obtained by the difference average calculation with the data in the current well drilling to obtain the target cuttings monitoring data. The data in the current drilling is acquired in real time by the drilling working equipment and sent to the terminal.
Because the laser radar scanning and the shooting of the camera equipment have fixed rates, the terminal obtains multiple groups of data in fixed interval time. Therefore, the fixed interval time may be set to 1 to 2 seconds, and the data obtained in this fixed interval time is difference-averaged.
The electronic data obtained by radar scanning and shooting video can be different from the real data, and after difference value average processing, the electronic data can be corrected, so that the electronic data is continuously close to the real data, and the error is reduced.
206. The terminal inputs the video stream data into a pre-trained machine learning model so as to calculate a prediction result, wherein the machine learning model is a convergent model obtained by training 3D point cloud data, video stream data and data in drilling;
in the embodiment of the application, the machine learning model is a model which is prepared by simulation before the monitoring work starts, and in the normal monitoring work, the machine learning model can directly execute the work. The machine learning model is an image processing model, and the input model is image data, namely video stream data is required to be sent into the machine learning model for calculation, so that a prediction result is obtained.
For example, before monitoring, the data of the outlet of the vibrating screen needs to be scanned and shot, then step 205 is performed to obtain a large amount of rock debris data of the outlet of the current vibrating screen, and the rock debris data of the outlet of the current vibrating screen is used for building and training a machine learning model.

The construction of the machine learning model can calculate the data of the vibrating screen outlet under the normal condition of rock debris, so that the follow-up comparison with the monitoring data is facilitated, and whether the monitoring data are different or not is judged.
207. And the terminal monitors the rock debris condition of the vibrating screen opening according to the target rock debris monitoring data and the prediction result.
In the embodiment, the terminal comprehensively judges whether abnormal conditions exist in the rock fragments at the vibrating screen opening according to the target rock fragment monitoring data and the prediction result; if yes, the terminal sends out an abnormal warning and continues to monitor work; if not, the terminal continues to monitor the work.
The laser radar can generate rock debris 3D point cloud data with depth information, the imaging equipment can more accurately record the condition of the vibrating screen outlet, and meanwhile, the terminal is used for assisting in processing data, so that a discrimination warning system is established, and the rock debris condition can be monitored in real time.
