Background and challenges

Oil field plays an important role in the national economy and the local economy, and the protection of oil exploitation has become one of the important work in the petroleum and petrochemical enterprises. Oil field distribution of the oil production point is relatively fragmented, and some are several hundred meters apart, and some are a few kilometers apart. Usually only a small amount of staff is responsible for the maintenance, monitoring and safety of the outdoor oil production machine and the indoor water pump, and it is not conducive to the centralized management of the center.

With the information construction in oil field, the internal management of the oilfield from extensive to intensive transition, and gradually strengthen the centralized management of oil production process, superior management unit also hope to subordinate enterprise facilities operating conditions, the field sudden events were timely and comprehensive understand and master, so oil well remote video surveillance, set transmission station library automation monitoring and control platform is deployed.

The main problems faced by video monitoring system at the present stage:

1) the application effect is poor - the image resolution of the monitoring points is low, can only solve the "see see" problem, can not meet the "see" requirements;

2 security integration less - oil field video surveillance system and other security systems are mostly independent operation, did not establish a good linkage mechanism, the entire security system is large and scattered;

3) network is difficult -- to a wide range of field equipment, part of the equipment in the access platform for some reason has been unable to provide interface development package, but at the same time, the complexity of the network, private network and the public network access coexist, some areas only local access;

4) operation and maintenance difficult -- part of a network, in the face of a large number of video surveillance equipment, operation and maintenance workload is huge and hard to detect, often resulting in fault processing is not seasonable, so that greatly reduced the effect of video surveillance system.

Construction goal
Oil field as an important part of oil collection system, the importance of stable operation is self-evident. Using the integrated data network, the establishment of comprehensive monitoring system covering all oil fields, to video monitoring as the core, to promote visual production management, is to improve the safety management level of a major move.

In view of the status quo of the oil field system, we will use iVMS-9800 video platform and environment monitoring system, establish a adapt to oil production safety comprehensive monitoring and control system of modernization, to the front end of the operation, business, equipment management, and meets the demand for superior platform for centralized management and hierarchical view, classification supervision, realize the multi-level network and cross regional monitoring, the monitoring center of all levels of the front-end system centralized monitoring and unified management, production safety escort.

Solution

The solution scheme of digital video monitoring system is mainly used in the construction and improvement of the video monitoring system of Digital Oilfield at all levels. The system topology is as follows:

The video supervision system of Digital Oilfield comprehensive use of HD, intelligent, networking, application of 3G technology, under the guidance of the principle of "standardization, integration, intelligent design, the standardization of industry products, to achieve the following functions:

1) HD video surveillance: full access to 720p and above HD cameras, enhance video quality and the level of security, (equipment, instrument readings and facial features) to meet the needs of the details of the monitoring, support for high-definition video storage;

2) intelligent analysis and identification: equipment status analysis, behavior analysis, license plate recognition;

3) auxiliary system integration: in addition to the realization of video monitoring, security, system integration, but also integrated environmental monitoring, access control, intelligent control subsystem integration, each subsystem according to plan linkage;

4) three-dimensional supervision mode. Wellsite / station, operation area, secondary units, branch / Administration multilevel vertical supervision, fixed network by C / s and B / S mode access, mobile network through the mobile terminal (mobile phone, platform, etc.) on site supervision;

5) system operation and maintenance management: IT infrastructure management, video quality diagnosis, bandwidth optimization and control, asset management, log management.

Program highlights

1) the wellsite / station configuration regular inspection plan, and the intelligent video analysis technology, deployment of the work site, once found to have people enter the security area can trigger the alarm.

2) support with the oil field SCADA production system docking, when the video monitoring system to receive the SCADA system forward RTU alarm signal, the video can be linked to a preset position, the real implementation of the visual operation management.

3) site using a dedicated smart ball, filtered using the intelligent algorithm of periodic motion kowtow machine behavior, through pattern recognition to achieve complex scene of intelligent analysis application.

4) for wellsite transmission bandwidth is not stable, the front end of the timing capture mode, alarm is triggered to upload video, to save bandwidth.
