1. Basic situation:
An oil production plant in an oil field consists of multiple oil wells, metering stations, manifold valves, transfer stations, joint stations, crude oil export systems, oil tanks, and other dispersed facilities in the oil field. Then the various facilities of the entire oil production plant work The status and data of the produced oil (mainly temperature, pressure, flow, etc.) are directly related to the stability of oil field production and the quality of crude oil. At present, most of the manual inspections of equipment operation status and measurement and statistics of oil production data are carried out daily. Due to the large number of oil wells and the distribution area of several hundred square kilometers, the labor intensity of workers will inevitably increase, and the real-time and even accuracy of equipment monitoring and oil production data will be affected. There are also hidden dangers such as clerical errors and fraud. This will result in the upper-level not being able to understand the on-site situation in time, and will not be able to formulate more effective and flexible processing plans based on the actual labor, electricity, and raw material consumption data consumed in production. Therefore, it is extremely prominent to improve the automation and informatization level of oil production plants.
With the rapid development of network information and the accumulation of production data, the traditional management methods and manual data recording mode can no longer meet the development requirements of modern enterprises. The real-time collection of production information, the networking of data statistics and query has become an effective means for modern enterprises to improve work efficiency and reduce production costs. To realize real-time collection and data analysis of on-site data and equipment information, remote command delivery, and equipment control, there is an urgent need for widely distributed on-site production data to be networked.
2. System plan:
2.1. System overview:
The oilfield production information intelligent monitoring and management system uses temperature sensors, pressure sensors, flow sensors and three-phase multi-function meters installed on the head of the pumping well to realize the detection of oil well electrical parameters and expand other parameters of the oil well, such as wellhead temperature. , Pressure, motor temperature, current curve, indicator diagram, etc., with the control functions that can be achieved on the oil well (alarm, dry pumping control, timing start-stop control, real-time energy-saving control, lack of phase load over-limit shutdown control, start-stop Remote control, etc.). Due to the large range of oil fields, the distance between monitoring points and between monitoring points and the monitoring center is very long, it is difficult to set up a wire network, even if the oil field with better conditions is to set up a wire network, the initial investment and maintenance costs are very high.So this plan adoptsGPRSThe wireless networking mode realizes the transmission of information and data between the monitoring points and between the monitoring points and the center.
The oilfield production information intelligent monitoring and management system can do effective statistics and analysis of this data. The monitoring center is usually located in the wired local area network in the factory area and is connected to the office management network. The management server of the monitoring center is responsible for the release of all data within the network. Relevant personnel of the plant management can directly log in to the server of the information center through the office local area network to perform real-time monitoring and query various report data. You can also browse the data through the Internet interface for engineers on business trips in other places.
