At the same time, the Internet of Things can optimize the production management process, create conditions for refined management, and provide reliable guarantees. It has important practical significance for the production development and planning of the future global society.
Yumen Oilfield, as the pilot and promotion unit of PetroChina’s oil and gas production Internet of Things system (A11 project), has built an Internet of Things experimental area for oil and gas production in Jiudong oil production area in 2013, and continues to develop Yumen Oilfield on the basis of the construction of the experimental area. The construction of the Internet of Things for oil and gas production is based on the automation of production operations and the optimization of production management processes, focusing on the needs of Yumen oil and gas production and operation, improving daily work efficiency, and then optimizing labor organization and employment, serving the refined management of oilfield production, and finally achieve “” The purpose of saving people, saving energy and saving operating costs”.
customer challenge
Jiudong trial mining area is located 46 kilometers east of Jiuquan City. Since exploration in 1984, industrial oil flows have been obtained in the Changshaling structural belt, which is another main battlefield for Yumen Oilfield to increase reserves and production after Qingxi Oilfield. The surface of the area is Gobi and desert, the terrain is flat, and the average altitude is about 1600 meters. The Lanxin Railway, the high-speed railway, the 312 National Highway, the Qingjia Expressway, and the West-East Gas Pipeline run through the whole area. Villages, schools, and farmland are distributed in the area, which is an area with special requirements for safety and environmental protection.
Due to the wide-ranging and harsh environment of oil and gas field exploitation, oil and gas gathering and transportation, power supply, water supply and other industries, according to production management requirements, remote and scattered on-site RTU, DTU,collectorThe collected stock values, status values, working parameters, and on-site images are transmitted to the corresponding master station or on-site integrated monitoring system. These collection terminals have a small number of single-point data and frequent transmissions; there are various types of collection points, which may be scattered in multiple locations. work site.
In order to meet the efficient, stable and safe transmission of production data, control information, video images and other content in the oil and gas production Internet of Things system (A11) project, it is urgent to quickly build a wireless communication that seamlessly covers oil, gas, and water between single wells and metering. The internet. Network construction should fully take into account the distribution and data transmission needs of individual wells and metering in each oil and gas field, and fully consider the characteristics of coverage capability, transmission bandwidth, networking capability, security, maintainability and management capability, and project implementation difficulty. Select the most suitable technology to build a dedicated wireless heterogeneous network for oilfields. In terms of technology selection, the types of technologies used should not be too many, and the wireless network networking architecture should be as simple as possible to facilitate the operation, management and maintenance of the network in the future and reduce capital investment.
? solution
In response to the wireless transmission construction requirements of the oil and gas production Internet of Things in the Jiudong Experimental Area of Yumen Oilfield, Potevio focuses on serving customers, adopts the deployment strategy of high practicability, high cost performance, high reliability and high scalability, and deeply customizes industry-specific, A “robust, resilient, efficient and economical” LTE230 wireless broadband communication solution that can be combined with wired networks. It has launched a three-dimensional supporting scheme including a wireless acquisition scheme for oil and gas field production data and a monitoring video transmission scheme for oil and gas field operation areas.
LTE230 Petroleum wireless private network is based on LTE core technology, adopts all-IP network architecture design, combines the characteristics of 230MHz frequency band, and has the characteristics of low cost, wide coverage and large capacity. The use of LTE230 system for cellular coverage meets the business needs of Yumen Oilfield, such as the special terrain, scattered production sites, and video surveillance in key areas, greatly reducing the equipment investment per unit area, as well as reducing bulk such as towers and computer rooms. Investment in supporting facilities.
The new system aims to realize the construction of oilfield automation information, adopts the system architecture of distributed acquisition and centralized monitoring, provides a new technical platform for the centralized management of the mining and transportation process, and can provide a management platform for the informatization and digitization of the oilfield.
The automatic collection of production data covers oil and gas wells, metering rooms, oil and gas processing stations and related gathering and transportation pipeline networks. By installing automatic data collection devices such as transmitters and sensors at well sites, station warehouses, etc., various production data can be collected in real time. Then through the RTU, DCS and other controllers to store, process and read the data, provide timely and accurate data support for the production operation management system, production command system, management decision-making system, etc., so as to realize the timely understanding of production operation dynamics and assist management decision-making. the destination.
? Customer benefits
The construction of the Internet of Things is the best opportunity for the current informatization innovation of the petroleum industry. Using 4G wireless communication technology, it can rely on low investment and low use costs to realize the “ubiquitous perception” of production and safety, and quickly and efficiently obtain the past due to technology and Cost barriers are important parameters that cannot be monitored in real time, nor can monitoring data be used to assist subsequent management, so as to achieve the goals of production quality and energy saving and consumption reduction.
The LTE230 wireless broadband communication system based on the wireless communication application requirements of the petroleum industry provides a wireless broadband data acquisition solution with industry characteristics, which meets the application requirements and specific characteristics of the Internet of Things in oil and gas field production. The LTE230 system equipment is used for wide-coverage cellular networking, which meets the business requirements of coexisting wide and narrowband transmission requirements for oil and gas production, scattered work sites, and small data collection and regional intensive business requirements. Combined with the excellent diffraction capability of the LTE230 system, the equipment investment per unit area can be greatly reduced, and the investment in supporting facilities such as towers and equipment rooms can also be greatly reduced, and the personnel investment in equipment installation and maintenance is also reduced. Under the premise of meeting the application requirements of the coexistence of broadband and narrowband for wireless data acquisition at the well site, the LTE230 system equipment has a huge cost advantage.
Yumen Oilfield is in a critical period to achieve sustainable development. After the Internet of Things is put into use, the real-time upgrade of single well data has reached the second level, and the system scheduling has been improved to the minute level, realizing the information channel of single well, plant station and control center. High-speed and smooth, remote decision-making is more flexible and intuitive, and the information of remote and difficult-to-work areas is accessible. It helps Yumen Oilfield to achieve the development goals of reaching 1 million tons/year of crude oil production and building 3 million tons/year of characteristic high-quality refineries. Well and fast into the track of harmonious development.
