Therefore, this paper focuses on several aspects of research, hoping to improve the oil and gas transportation capacity.
The role of automation technology in oil and gas pipeline transportation
Compared with the traditional manual work, oil and gas storage and transportation supported by automation technology, More security and intelligent features, is conducive to reducing labor input, but also to a reasonable and orderly division of the work flow, production, storage and transportation projects for centralized management. In the present stage of oil and gas storage and transportation, automation technology mainly plays a role in the following aspects. First of all, the analysis from the perspective of enterprise leaders is conducive to providing decision-making basis. Secondly, from the perspective of production staff to help leaders make decisions. Again, using automation technology, can real-time monitor the production of various processes, that is, Y set, control the gathering station data. Finally, the use of automation technology is conducive to the realization of on-site problems, and can take a reasonable way to solve the problem, thus improving the stability and safety of the production process. At the same time, automation technology is used to promote the control of field data, thus ensuring the smooth development of the whole process. The specific role is as follows:
1.1 Detection of oil and gas storage and transportation monitoring system
The analysis of the past practice shows that oil and gas transportation, the main use of pipeline transportation, but because of the pipeline in the transport stage often appear various problems, such as oil and air transportation pipeline is too long, friction brings some resistance and so on. Therefore, the above two problems must be overcome to ensure sufficient pressure in oil and gas transportation. In the process of oil and gas operation management, it is necessary to accurately grasp the energy provided by pumping stations. But in actual production and transportation, friction resistance is not conducive to oil and gas transportation, temperature plays a key role in transportation. Therefore, it is necessary to strictly control the temperature of the heating station, and the staff need to do a good job in judging the work, so as to ensure the smooth progress of oil and gas storage and transportation. Only fully combined with automation technology and information technology, can improve the efficiency of gas storage.
1.2 Enhance the efficiency of oil and gas transportation equipment
In the stage of oil and gas storage and transportation, the consumption of electric energy can be used to improve the working efficiency of equipment, at the same time, the production efficiency can be powerfully improved, and thus promote the development of the storage and transport. In pipeline oil and gas transportation mode, the friction loss of pipeline depends on the length of pipeline. At the same time, the insufficient pressure of oil or gas transportation will lead to the low transportation efficiency. Meanwhile, affected by topography, geology and other conditions, many areas are not suitable for pipeline transportation. In order to improve the transportation efficiency, oil and gas storage tank transportation mode can be adopted. This requires the use of automation technology, compressed into the tank, and then transport the oil or gas storage tanks, to achieve more convenient storage and transportation. In the process of oil and gas pipeline consolidation, the use of automation technology is conducive to improving the efficiency of operation. Through the calculation of the collected information, the system consumption can be fully analyzed. Pump equipment usually will be affected by power consumption, by monitoring the automatic ability of pump equipment, detailed record pump equipment flow, as well as the pressure situation, in order to determine the pump equipment output power; Record the field data and analyze the application, change and influence factors of pump equipment. In order to facilitate the actual operation, effectively reduce the loss of friction, thereby reducing energy consumption.
Application of automation technology in oil and gas pipeline transportation
2.1 engineering automation control technology analysis
In the process of oil and gas engineering control, automatic control technology under the management of computer technology plays an important role in improving the quality and efficiency of engineering operation control. Especially in the control of crude oil storage and transportation, the technical support function of automation control technology is more obvious. In the actual process of crude oil storage and transportation, automatic control technology includes crude oil temperature and flow detection, information transmission, control host and heating control system. The main control principle includes the following steps: First, the crude oil flow rate and heating temperature are detected by the detection system. The detection data is reported to the control host computer through the information transmission system, and then the host computer analyzes the relationship between crude oil flow and temperature, and makes control judgment. If the flow of crude oil is too viscous, the host will make a control command to increase the heating temperature, thereby reducing the viscosity of crude to improve its flow; On the contrary, the main engine will make the order to reduce the heating temperature, and thus the oil flow. Finally, the control instructions of the host computer are transmitted to the heating device by the information transmission system to complete the automatic control process of crude oil transportation. Compared with the traditional crude oil control technology, the application of computer automatic control technology has the following three advantages: – The control efficiency and quality of crude oil storage and transportation can be improved through the automated control technology to ensure the stability of transportation; Second, the safety of crude oil storage and transportation is improved through automatic control. Third, through the effective management of heating equipment, the energy consumption in storage and transportation is reduced and the cost of storage and transport management is reduced.
2.2 Application of hydrate storage and transportation technology
Natural gas hydrate is a kind of solid crystal formed by liquefied natural gas at a certain temperature and pressure. It is also a new energy situation in oil and gas exploitation. The main advantages of applying the gas hydrate directly to the city gas supply include the following points: first, the secondary vaporization and release process of the crystal is regular, and is beneficial to the control of technicians; Second, the use of water-hydrate natural gas performance is good; Third, small size is convenient for transportation; Fourth, the safety factor in the process of storage and transportation is high. Because of its advantages, this technology has been widely used in natural gas storage and transportation in China, especially in small and medium-sized cities.
2.3 New storage and transportation space and supporting system cleaning technology
In oil and gas storage and transportation engineering, oil storage space of tank car and other crude oil storage and transport space, heat exchanger, boiler and other supporting systems, the technical personnel pay more attention to the problem of fouling. Because the presence of scaling can cause the following three problems. – Is excessive fouling will reduce the storage space, reduce its normal reserves; The other is that the fouling will increase the impurities in crude oil and decrease the quality of crude oil. Third, excessive fouling in the supporting system will reduce the heating and operating efficiency of the system, and improve its operating costs. The traditional storage and transportation cleaning technology has low efficiency, high cost and poor overall effect. Therefore, in the technical research, technical staff carried out a new cleaning technology research. In the research, we found that high-pressure water jet cleaning technology in the cleaning process, for the heating system, small storage and transportation space cleaning can play a good role. The automatic modular cleaning technology has been widely used in the cleaning process of large oil tanks and sealed oil tanks. The representatives of this technology include BLABO cleaning system, COW cleaning system and so on, which are commonly used automatic cleaning system in large tank storage and transportation.
In short, in order to realize the application of automation technology in the process of oil and gas storage and transportation, It is necessary to further implement effective technology, and at the same time, to continuously develop more effective equipment, in order to meet the modern development, to achieve the efficiency of oil and gas transportation, through further reasonable monitoring, to ensure the safety of the whole process of oil & gas transportation. For the relevant staff, they should continue to learn, to provide effective support for effective technological innovation so as to truly realize the full automation of oil and gas transportation, and help the development of national undertakings.
