Study And Implementation Of Monitoring System Networking For Oil Well Based On Wireless Sensor Network

Wireless sensor network (WSN) is a new kind of network technology for communication. It achieves the integration of many technologies, for example, sensor technology, embedded computer technology, communication technology, distributed information processing technology, micro-electronic manufacture technology and software programming technology. It can monitor, collect, transfer and process the real-time information of the object and environment in the area covered by the network. Wireless sensor network has the characteristics of low cost, low power and high mobility, and is easy to implement. So it can be applied in many areas such as industry, environment, aerospace, intelligent house, military, and so on.As so far, many problems widely occur in oil producing, for example, the stolen of crude oil, pipeline leakage, abrupt change and sudden stop of oil production. These problems not only can cause great economic losses, but also pollute the environment seriously if not detected in time. Seriously speaking, serious accident such as fire and explosion can also happen. It has been founded that pipeline leakage and production stop can cause corresponding changes to the pressure and the temperature of the pipeline. And a set of fault diagnosis theory based on the changes of pressure and temperature of the pipeline has been developed on the basis of the aforementioned work. But manual measuring can't fulfill the industry need because of its high cost and low efficiency. So a kind of reliable and effective monitoring solution is needed urgently.In this paper, after investigating the victory oilfield and combining with the above detecting theory, a kind of field real-time monitoring and alarming system with the characteristics of low cost and low power is developed using WSN technology. This network system can be used to performance real-time monitoring of oil well and oil pipeline, so that problems such as pipeline leakage and production stop can be detected and controlled in time. So it can reduce property loss and environment pollution, and can prevent accident effectively. Meanwhile, the tendency of oil production can also be obtained via this network system to help the manager to make future policy. And it's useful to improve the management of the whole enterprise.In this paper, we do deep research on design of the construction and operation of the Wireless sensor network monitoring system. The network system, which consists of sensor node, sink node and manager node, is divided into two stages and achieves data sampling, communication and processing. Wireless sensor network QoS(Quality of Service) technology is adopted to achieve anti-interference design of the channel detection and migration. It is ensured that the sensor network has a longer life circle due to the low power design of the hardware and software for the sensor node. For the sink node, parameter configuration, protocol transition, and data retransmission, and data backup, and alarm functions are achieved by using operation system design idea and coordinating different tasks. This greatly improved the stability, reliability and extensibility of the network system. Data storage, processing and analysis are implemented via the manager node and the database server management software. The sensor node in the network system is powered by battery, so it is of small size, and is easy to install, and performances well in anti-destructiveness. The communication network uses free ISM frequency and is wireless. So the cost is low, and it's easy to install and maintain.Finally, performance of the system is tested for many times on two testing network and the data sampled are quantitatively analyzed, in order to run the system designed on the oilfield. It is shown that this system achieved detecting and monitoring of the oil pipeline. Additionally, it validates the effectiveness of the system designed in monitoring the oil production.
