Design Of Remote On-line Monitoring System For Oil-well Based On GPRS

After our country join WTO, the oil extracting industry is influenced by the international price of crude oil. Depletion of numbers with the improve of efficiency, reducing the cost, and increasing the safety level is a emphasis task from now till a certain future. Automatize the oil well remote monitoring system is a necessary way to approach the modern oil production, and is also necessary for the improvement of the oil trade competition. The paper rooted from a certain oil well reconstruct project. And the mail task is to realize the remote monitoring and on watch without person of the oil well and construct the digital monitoring system.It is a fact that the oilfield is always far away for the city and has a bad transportation and telecommunication condition. According to the fact mentioned above , in this thesis , we have developed one monitoring system based on the GPRS remote data transmission network, in order to find out hidden trouble , improve working efficiency and economic benefit, improve worker's working conditions. The system including hundreds of RTU terminals and control center software, can sample current, voltage, temperature, pressure, load and position data according to the parameter preset by the control center and then send the data to the network through GPRS network. So the control center which must have the fixed IP address, can receive the working status data through INTERNET according socket protocol. Anymore the control center making use of monitoring client software can handle all these data, such as display, print, report and so on. Also the center can set terminals' working parameter and can make anyone of the terminals to send continues status data in order to analyses power-calculation-plot curve.This paper put forward a new type of oil well remote on-line monitoring system, and realize the whole design, the system is in application in june.2004, and runs well. Also improve the work efficiency with the depression of the cost. It not only reflects the rationality, practicability and advancement in practice, but also has the value of engineering reference.
