Automatic monitoring method of oil drilling polluted gas based on water flow segmentation

Abstract

The invention belongs to the technical field of automatic monitoring of polluted gas in oil drilling, and discloses an automatic monitoring method for polluted gas in petroleum drilling based on water flow segmentation. Frame data can save a lot of time. The water flow segmentation algorithm is used to segment the water flow to obtain the morphological information of the water flow, and the abnormal monitoring algorithm is realized by multivariate Gaussian, which is used to identify abnormal data frames. Through the automatic monitoring algorithm of oil drilling pollution gas based on water flow segmentation, the water flow of oil drilling drainage pipeline is divided and then according to the segmentation results, whether the polluted gas meets the emission standard can be detected in real time. The problems of lack of supervision in manual observation and the inability of water flow sensors to obtain the changing shape of water flow in real time can effectively save labor costs and protect the environment.

Description

technical field [0001] The invention belongs to the technical field of automatic monitoring of polluted gas, and in particular relates to an automatic monitoring method for petroleum drilling polluted gas based on water flow segmentation. Background technique [0002] At present, the closest existing technology: pollutant discharge and treatment, which is related to the environment and people's livelihood, is an indispensable part of industrial production. In the process of industrial exploration and excavation, in addition to underground useful resources, some pollutants, such as H 2 S, polluting gases will follow the industrial drainage pipes to the ground. H 2 S gas is a toxic and harmful acid gas, which is directly discharged into the air and has an impact on the surrounding environment. When the content of the polluting gas is higher than the emission standard, the emission needs to be treated. H 2 In addition to being toxic and harmful, S gas is also a colorless, ...

AI Technical Summary

Problems solved by technology

When monitoring the change of water flow in the drainage pipe, if the water flow suddenly sprays, the data obtained by the water flow sensor may be inaccurate. At the same time, due to the impact of the water flow, the installation of the sensor is also a problem

Therefore, the water flow sensor cannot be used to judge whether the emission of pollutant gas meets the standard

[0004] To sum up, the problems existing in the existing technology are: in the monitoring of polluted gases, there are waste of human resources, high cost, visual fatigue, and the problems that the existing water flow sensors cannot meet the actual needs through manual methods.

In reality, the difference between water flow and human body is that the shape of water flow is not fixed, so it is difficult to capture the change of water flow shape through the change of information such as optical flow, that is, the existing video anomaly event detection method is not suitable for pollution gas. monitor

At the same time, the background of the image is complex, involving different light intensities and changes in background objects, so it is difficult to cut out the background through traditional image algorithms
