Oilfields/natural gas fields are mostly located in swamps, deserts and basins, shallow seas, etc. Because of the remoteness of urban areas, transportation and communication facilities are relatively backward. Oilfield/natural gas fields based on WLAN technology are mostly located in swamps, deserts and basins, shallow seas, etc. Because of the remoteness of urban areas, transportation and communication facilities are relatively backward. The establishment of wireless local area network based on WLAN technology to realize wireless data communication has many advantages such as quick installation, convenient maintenance and migration, and low cost. Application 1: The wireless monitoring system sets up wireless monitoring points in the production sites of single wells, counting stations and joint stations in the oilfield mining area with a radius of several tens of square kilometers. In the oil field general control room, the system central base station is established. Select carrier-grade wireless bridge products, cooperate with high-gain antennas, and use point-to-multipoint wireless connection to establish a wireless transmission main link between the oil field control room and each monitoring point to realize production site image information, production data, and equipment operation. Real-time dynamic transmission of data, crude oil reserves and transportation information provides accurate and timely first-hand information for command and dispatch of oil production.
At the same time, in many unattended oilfield production areas, the safety and security of crude oil and its production facilities is also the top priority of the relevant departments. The wireless remote video surveillance network at the production site provided strong support for the safety and security work at the production site, and guaranteed the rapid blow of the oilfield security department against illegal criminal activities.
Each monitoring point consists of two parts: video acquisition and processing system and signal transmission system. The video acquisition and processing system includes camera, pan/tilt and its controller, and network video server. The signal transmission system consists of wireless bridge and antenna feeder system. . The system uses advanced digital processing technology to process the image information captured by the surveillance camera into a TCP/IP-based data packet, which is transmitted to the remote monitoring center through the wireless network.
The monitoring center base station is composed of a carrier-grade wireless bridge and an antenna feeder system. The functions of real-time display, archiving, and query of monitoring images are all completed by computer systems or digital hard disk recorders. Through the authorization, the sharing of system resources can be achieved, and the remote monitoring through LAN or INTERNET can be realized. The remote monitoring center can also control the front-end surveillance camera, and shoot the production scene video images of different orientations and different scales according to the needs of the operators.
Application 2: Data acquisition system to improve the basic data acquisition level of exploration and development, monitor the pumping unit load, electric submersible pump well and screw pump shaft motor power "target=_blank> machine current, power factor and other equipment operation data, real-time acquisition and transmission A number of exploration basic data such as wellhead pressure, wellhead temperature, bottomhole flow pressure, and bottomhole temperature are selected. The carrier-grade wireless bridge is used in conjunction with the antenna feeder system. Combined with various data acquisition equipment, a wireless data acquisition system for exploration and development can be built.
In this system, with the superior coverage characteristics and data acceptance sensitivity of carrier-class wireless devices, real-time transmission of various data information of the exploration and development process through the wireless network is realized. In the area covered by the wireless signal, whether it is a fixed receiving point or a vehicle-mounted mobile receiving point, the data information collected by the drilling point can be received in real time, which ensures that the central control room can quickly and accurately grasp the working status of each oil well in the jurisdiction, and timely discover Hidden dangers, at the same time realized the timely collection and storage of basic data, and improved the basic information collection system for oilfield exploration and development.
