Research And Realization Of Oil Well Monitoring And Analysis System Based On Web Service

With the rapid development of network and communication technology,the remote monitoring in the industrial control field has been greatly developed.In the scene of oil field which with the scattered layout and with few people in it,the company really need make a real-time collection of well data in order to keep abreast of the oil scene.Therefore,there has a urgently need of cross-platform,cross-system remote monitoring system in the market,which can make function connect to field production closely,and equipped with reliable communication system.Web Service is the basic building block of the distributed computing on the internet.It is one of the widely used technology in the integration of enterprise application.This paper has build an oil well field monitoring and analysis system based on the technology of Web Service,which can distributed in different platforms.In this system,the well data achieved by monitoring instruments is transmitted to the database server in the case of Socket communication protocol through the GPRS data transmission technology,then Web Service distributes all the function module interfaces on the internet in the case of service,the client can achieve those interfaces through the SOAP communication protocol,by achieving those interfaces,the users can get the data they want.The next,we will introduce the main contents of this paper:(1)First,we designed and explained the architecture and topology of the oil monitoring and analysis system,then we made a demand analysis for the system and gave the description and case diagram for the system's function.(2)Second,we defined the data format of the Socket communication protocol between the well measurement instruments and the database server,and the data storage format on the database,and we also realized the effective and safe storage of the real-time data on the server;(2)Third,we realized the service interfaces of Web Service,then we registeredthose interfaces to the management server through the Web Service,and published the WSDL document to describe those service interfaces.Then we established a browser-side client for the real-time monitoring system by using those service interfaces;(4)The last,we eased a function that applying the problem that Web Socket into Web Service to solve the problem that the Web Service has a large dedication in data transmission and can not transmit the data instability when the data is too big.The experiments proved that this method can effectively improve the efficiency of data transmission between server and client.In this paper,we designed a mature and stable oil well monitoring and analysis system from the hardware to the software,which has a great practical value.
