GPRS oil well remote automatic monitoring system

GPRS Oil Well Remote Automation Monitoring System

Foreword:

One oil field in an oil field consists of multiple oil wells, metering rooms, manifolds, transfer stations, coal stations, crude oil transmission systems, oil tanks, and other decentralized facilities in the oil field. The status and data of the produced oil (mainly temperature, pressure, flow, etc.) are directly related to the stability of the oilfield production and the quality of the crude oil. At present, most of the manual daily checks of equipment operations and measurement and statistics of oil production data. Due to the large number of oil wells and their distribution range from tens to hundreds of square kilometers, this method will inevitably increase the labor intensity of workers and affect the real-time and even accuracy of equipment monitoring and oil production data. Therefore, the automation and informationization of the oil field are extremely prominent.

The oilfield monitoring and control system based on computer and GPRS wireless communication module can greatly improve the oilfield production efficiency, reduce the overall cost, and realize the automation and informationization of oil field production and management. In order to achieve this goal, it is necessary to develop a reliable oilfield monitoring and operating system based on microcomputer technology and modern communication technology; develop new and inexpensive oilfield operation monitoring methods; and develop a database and recording system that is easy for users to access.

system introduction:

Oilfield well remote automatic monitoring system, through the sensors fixed on the rack, management personnel can quickly understand the working pressure of the various wells, oil production voltage, steam temperature and other data through the system without leaving the home, data related to well work After 10 minutes of transmission, once the failure of the well, the diagram will be marked exclamation point, maintenance personnel will be able to rush to the scene in the shortest possible time, timely troubleshooting. This ensures the safe operation of the well.

Oilfield well remote automatic monitoring system consists of three parts: data center, well monitoring point, and user's mobile phone.

1. Data Center: Mainly composed of PC and PC software, it realizes information management such as data receiving, storage, display, data request, curve display, and report printout, as well as monitoring and warning of special conditions and customers. Side software provides easy access to real-time and historical data.

2. Oil Well Monitoring Point: Real-time data of temperature, pressure, flow rate, etc. of the site is collected into the data collection terminal, and an automatic alarm of the collection point is realized according to the real-time data to prevent accidents.

3, the user's mobile phone: access to the data center through the 3G smart phone to collect real-time data or edit text messages sent to the data collection terminal to collect real-time data on the scene.

System topology:

The main function:

â—† It can continuously collect and record the data of voltage, current, electricity, temperature, pressure, flow rate, liquid level, interface, water content, dynamometer chart, infrared alarm, etc. of the monitoring point 24 hours online in real time. Various methods such as images are used to display and record monitoring information in real time. Monitoring points can be expanded up to thousands of points.

â—† The temperature, pressure, flow and other alarm limits of each monitoring point can be set. When the monitored point data is abnormal, it can automatically send an alarm signal. The alarm modes include: live multimedia sound and light alarm, network client alarm, telephone Voice alarm, mobile phone short message alarm, etc. Upload alarm information and perform local and remote monitoring. The system can notify different on-duty personnel at different times.

◆ The data center software uses the standard windows 98/2000/XP full Chinese graphical interface to display and record the voltage, current, electricity, temperature, pressure, flow, liquid level, interface, water content, display power graph, and infrared alarm in real time. Changes in data curves, statistics of historical data, maximum, minimum, and average values ​​of voltage, current, electricity, temperature, pressure, flow, liquid level, interface, water content, dynamometer, infrared alarm, etc., cumulative data, Alarm screen.

â—† The monitoring host computer can use the monitoring software to print data and running reports of voltage, current, electricity, temperature, pressure, flow, liquid level, interface, water content, dynamometer chart, infrared alarm, etc. at any time.

â—† Powerful data processing and communication capabilities, using computer network communication technology, any computer in the LAN can access the monitoring computer, online view voltage, current, electricity, temperature, pressure, flow, liquid level, Interface, water, power diagram, infrared alarm and other data changes, to achieve remote monitoring. Not only can the system be monitored in the duty room, leaders can easily watch and monitor both in their offices and on their smartphones.

â—† The system can expand a variety of record data analysis and processing software, can draw bar graphs, pie charts, curve fitting and other processing, can be output in TEXT format, but also can enter EXCEL spreadsheets and other office software for data processing.

â—† Interfaces are reserved for system design, and hardened software devices can be added at any time. The system can be completed in a very short time with only minor changes. New content may be added at any time in accordance with changes in policies and regulations.

main feature:

â—† Practicality: Oilfield oil wells are geographically dispersed. Therefore, high signal capture over a wide range of GPRS networks is used. High-gain antennas are necessary to ensure the normal operation of the network.

â—† Real-time: Using the latest communication and hardware and software technologies, it has established a clear and reasonable system architecture, which can realize multi-threaded remote concurrent communication. In a few seconds, hundreds of data collection terminals can be transmitted in real time. The centralized monitoring and remote scheduling are performed at the monitoring center to realize timely alarming of failure information.

â—† Scalability: The system or module can be infinitely expanded to facilitate long-term upgrades and maintenance. The system's life span is extended. By updating the components, the system can continue to exist without causing the entire system to crash, resulting in large investment losses.
â—† Easy maintenance: The system can execute corresponding remote operation commands for remote data collection terminals, including remote parameter settings, remote control, remote data copying, remote terminal reset, and remote terminal software upgrade.

â—† Easy to operate: The system software is functional, modular, and graphically designed. The whole process is Chinese-language help, and the operation is simple and convenient.
â—† High cost performance: The system is tailor-made for remote monitoring of oil wells, fully taking into account the business needs of all aspects of the oil well.
