Description of oilfield business scenarios
With the construction of the oilfield automated information system, the previous extensive management of the oilfield troops has transitioned to information management, and the centralized management of the oil production to oil transportation process has been gradually strengthened.It requires the establishment of a multi-system monitoring platform including remote video monitoring of oil wells, automation systems for power distribution lines, leakage monitoring of oil pipelines, automated monitoring of gathering and transportation stations, etc.The purpose is to use the on-site monitoring system to realize automatic collection of data at the source, and to automatically load the plant-level real-time database with the help of the existing network resources of the oil field, which is suitable for management departments at all levels.Provide an open data platform to enable production and management personnel to control and master the production dynamics in time, so as to realize the automation of the entire production process;Statistics, analysis, and optimization of data provide an important basis for ensuring the normal operation of production equipment and reducing production costs.

1.Demand background
Oil and gas fields are usually distributed in swamps, deserts, basins and shallow seas far away from cities and sparsely populated areas. Due to the characteristics of their working environment and nature, there are the following problems in the control management and safety protection of this field:

1、 Oil and gas fields are usually located in the outer suburbs, sparsely populated and wide. There are relatively few on-site watch and maintenance personnel. The traditional working method is that the staff patrol and inspect according to the shift arrangement, and each team usually has one to three people. Due to the distance between the places to be inspected and the special environment of the oil depot, vehicles are not allowed to enter casually, so the staff need to walk in the divided area. It takes ten to twenty minutes to walk between each station, and the staff workload is very large.

2、 The working environment of oil and gas fields is highly dangerous, and once leaked, it will have a significant impact on human body and surrounding environment. At the same time, the consequences of explosion and combustion caused by oil, natural gas and other raw material resources involved in oil and gas fields are immeasurable.

3、 Offshore oil fields are in high salt fog scenes, and other flammable and explosive gases often leak, so it is necessary to view relevant videos in real time.

Therefore, we should pay attention to three aspects of safety in production engineering:

First, the production and operation status of the working equipment of the oil and gas production plant, such as whether the oil tank and valve leak, and whether the transmission pipelines of natural gas, kerosene and petrochemical are burst or damaged intentionally or unintentionally;

Second, supervise the compliance operation in the loading and unloading project of raw materials and finished products of oil and gas production plant, such as supervising the incoming and outgoing vehicles, recording the license plate number of incoming and outgoing vehicles, and supervising whether the staff violate the rules, such as smoking and using lighters;

Third, the perimeter guard alarm system to prevent the intrusion of non relevant personnel for theft or sabotage activities

1.Real time video monitoring in oil production area

Oil production well pad: the main task is to realize the real-time monitoring of vehicles entering and leaving the operation area of oil production well pad, loading and unloading, equipment operation, staff work and the surrounding environment of oil production plant, so as to ensure the comprehensive and effective control of vehicles, personnel and places in each area.

Oil production area team office area: the main task is to check the access conditions of vehicles on the main roads of the oil production brigade, and monitor the office area and surrounding environment in real time, so as to ensure the comprehensive and effective control of vehicles, personnel and places in each area.

Monitoring system: it can realize 24-hour monitoring video and zoom function through PTZ control, adapt to complex outdoor environment, have fog permeability function and low code stream transmission function, and adopt infrared explosion-proof camera at night.

2.Regional invasion

Most of the oil production operation areas are located in the wilderness, and the oil production area realizes unmanned management. In order to prevent malicious damage or oil theft, people or vehicles need to enter the oil production operation area and give an alarm immediately.

3.Alarm linkage voice playback

In case of accidents, relevant personnel can be notified to the site in time for proper treatment, and all the events can be recorded in detail and clearly for future investigation and evidence collection. For the alarm information generated by intelligent analysis, the brigade monitoring center will immediately give an alarm prompt, automatically record the alarm, open the on-site monitoring information and shout remotely.

2. Demand analysis
1.Explosion proof type

In areas 0, 1 and 2 of the oil and gas field area, it has the characteristics of flammability and explosion, including that under normal temperature, the gas in the air of the site reaches a certain concentration and will cause explosion in case of open fire. Therefore, the explosion-proof requirements of the front-end system and transmission process in this field. The state stipulates that there shall be no open fire within 100m of natural gas, oil, diesel, gunpowder and explosives. Explosion proof cameras shall be strictly equipped according to different explosion-proof levels of cameras.

2.Waterproof and dustproof, day and night monitoring

Industrial monitoring requires high performance of the camera. It implements 24-hour monitoring and is used outdoors. Therefore, it is suitable to use explosion-proof gun with high definition and low illumination.

3.Large monitoring range

Cameras installed at entrances and exits, perimeter and open areas shall have wide vision, barrier free and wide monitoring range.

4.Lightning protection type

The lightning protection and grounding of front-end equipment directly affect the safety and reliability of the whole project. The lightning protection principle is that all equipment should be installed within the protection range of lightning rod. The weakest link of the field monitoring system for lightning stroke is the power supply. It is very important to do a good job in power supply lightning protection. The key to power supply lightning protection is to do a good job in grounding. Therefore, it is necessary to adjust measures to local conditions according to specific terrain.

5.Model selection

For the selection of the front-end camera of the video surveillance system, high-speed fastball, PTZ integrated camera, gun camera or a combination of the three are popular at present. The camera at the monitoring point is only selected by this girl according to the actual situation around the monitoring point and the focus of monitoring. The station valve chamber is in a dark environment, so it is necessary to use its own infrared camera.

6.Infrared thermal imaging

In order to solve the defect that it is impossible to monitor in real time in foggy weather or over a long distance at night, an explosion-proof infrared thermal imaging camera can be selected, which can capture the temperature difference of the surrounding environment, convert it into video images after back-end processing, and support intrusion detection and abnormal temperature detection. It can play an early warning linkage function through video image analysis.

7.intrusion alarm

The camera can realize intrusion alarm. When someone or vehicle enters the warning area, the monitoring screen will prompt the alarm information to remind the monitoring personnel to pay attention to the intrusion of suspicious targets. In the important dangerous areas of the finished oil depot, such as oil storage area, loading and unloading area, the camera is equipped with intrusion alarm to realize safety warning and advance warning.
