The petroleum industry has always been an important place for wireless network applications. The topography of the oil mine is uneven, and the oil production wells are distributed widely and far apart. The wireless network connection can provide a data link from the drilling rig to the compressor room in order to display and input important data obtained by the drilling. Another example is the difficulty of data and information transmission on offshore drilling platforms due to the barriers of wide waters. The cost of laying optical cables is very high, and the construction is very difficult. Using wireless network technology, the cost is less than one-tenth of that of laying an optical cable, with high efficiency and good quality.
Xinjiang Oilfield Branch is a regional branch of China National Petroleum Corporation (hereinafter referred to as the joint stock company), and is the largest oil producer in western my country. The company is currently mainly engaged in the main business of oil and gas exploration and development, gathering and transportation, and exploration and development research. Crude oil production ranks fourth in China’s onshore oil industry for 12 consecutive years. It has made great contributions to the country and Xinjiang’s economic construction, and is currently the main area for crude oil production in the Western Development. Karamay Oilfield, the main oil field of Xinjiang Oilfield Company, was the first large oilfield discovered after the founding of New China. On October 29, 1955, well 1 in Karamay area blew out a high-yield oil and gas flow, and the Karamay Oilfield was discovered. In 1960, the Karamay Oilfield produced 1.64 million tons of crude oil, accounting for 40% of the country’s crude oil output that year. Petroleum production base. Over the past 40 years, the Karamay oil field has been the mainstay and 17 oil and gas fields have been developed and constructed successively, including Baikouquan, Xiazijie, Cainan and Shixi. The oil and gas resources are very rich. The total oil resources are 8.6 billion tons and the total natural gas resources are 8.6 billion tons. 2.1 trillion cubic meters, the total oil and gas resources reached 10.3 billion tons. It is one of the three major basins in my country with total onshore oil and gas resources exceeding 10 billion tons. It has huge development potential and is a region where new large and medium-sized oil and gas fields are expected to be discovered in China. .
Over the past few years, each secondary unit of Karamay Oilfield has established and improved its own internal local area network. However, the network investment of each unit is different, and the network is difficult to set up due to some environments. Some are only connected to part of the important third- and fourth-level oil production. Units, and some second-level units only networked inside the office building.
The introduction of wireless networks
According to the geographical location of the oil production units in Karamay Oilfield, as well as their data communication information volume, data security, transmission distance and other characteristics, Shanghai Yiren Communication Terminal Co., Ltd. combines the characteristics of optical fiber, spread spectrum microwave, and WLAN three transmission technologies. , Provides a set of tailor-made wired + wireless + microwave solutions for Karamay Oilfield. In some geographically dispersed primary oil production units, oil production teams/operation teams in the field, and crude oil processing stations where wired networking is not convenient, spread-spectrum microwave products + wireless network products are used to achieve interconnection issues. The wireless spread spectrum microwave product Run5800 can achieve long-distance bridging of 20-50Km, and WLAN wireless local area network products can achieve short-distance bridging of several hundred meters to several kilometers to realize the oil production data of each oil production area, such as oil production and content. Real-time transmission of water and gas content with the oilfield information center. It has changed the original information collection method of sending special personnel and special vehicles to each oil production area to copy production data every day, greatly improving the efficiency and real-time performance of oil production data collection, and providing real-time, scientific management and production for Karamay Oilfield. The first-hand scientific basis has improved work efficiency and improved working methods.
Program features
1. Long transmission distance
For long-distance oil production areas, the “one-to-one” wireless microwave equipment Run5800 is used for long-distance transmission, which can reach a transmission distance of 50KM;
2. Flexible scalability
For the short-distance transmission from the main station of the oil production area to the oil production stations, the convenience of wireless AP installation can be used to quickly set up a point-to-point or point-to-multipoint wireless bridge, and flexibly increase or decrease the number of APs used;
3. Transmission stability
Run5800 microwave transmission equipment can ensure the stability of the transmission rate under the condition of long-distance transmission of tens of kilometers, and has strong anti-interference ability.
4. Good confidentiality
Due to the low-power spectrum radiation of direct sequence spread spectrum communication and the autocorrelation of the PN code, the signal radiated by it looks like noise. At the same time, it is difficult for a reconnaissance receiver dedicated to receiving electromagnetic signals to detect spread spectrum signals. exist. Even if a spread spectrum signal is detected, the content of the information cannot be interpreted because the length and phase of the PN code are not known. Therefore, it has considerable confidentiality characteristics.
5. Convenient erection, mobility, and convenient maintenance
The hybrid networking mode of wireless microwave equipment and wireless AP is easy to install and movable, which solves the problem that cannot be solved by laying cables. (For example, cross-river, cross-mountain, islands and other places that are not easy to lay) reduce the manpower, material and financial resources for laying cables and optical cables, reduce the scale of investment, and have a short network construction cycle, fast and flexible networking; good communication quality, The communication capacity is high; it is easy to manage and maintain, and has the advantages of a short recovery period after a failure.
