1 Brief introduction of oil pipeline installation technology
In the process of oilfield exploitation, pipelines mainly play the role of conveying media. Due to the particularity of the transported medium, the general pipeline installation may not meet the requirements, so the pipeline installation project should be carried out by professionals. This kind of project usually has a short construction period and great difficulty, so it is necessary to make corresponding plans for emergencies. The formulation of the plan should proceed from the overall situation and comprehensively consider all kinds of unexpected situations that may be encountered. The characteristics of oil pipeline installation technology are mainly reflected in the following two points: first, considering the particularity of transportation medium, the pipeline materials required to be selected can inhibit the occurrence of chemical reactions, thus ensuring the safety of transportation projects; Secondly, the welding part of the pipe network should avoid the influence of the conveying medium, which requires advanced pipeline construction technology to ensure the sealing of the whole pipe network system. With the rapid development of science and technology, pipeline installation engineering has entered the information age, and powerful information technology will further improve the quality of pipeline installation engineering.
2. The basic requirements of pipeline installation process
When installing petroleum process pipelines, preparations must be made in advance, and corresponding rules and regulations must be strictly observed during construction. The following will explain the basic requirements of oil pipeline installation technology: 1. Before installation, the construction site should be kept clean, and the main cleaning objects are waste residue, iron filings and other sundries brought by pipeline construction to avoid affecting the construction progress. In addition, for special parts such as pipeline welds, strict cleaning and sealing work should be done. Second, in the installation process, construction must be carried out in accordance with relevant regulations, focusing on the layout, direction and installation of pipelines in the project to ensure the smooth progress of the installation project as much as possible. It should be noted that the installation project can only be adjusted after the designer allows it. Third, after the installation, strict maintenance work should be carried out, and the parts that are easy to leak in the pipe network system, such as welds and switches, should be carefully checked, so as to leave corresponding space around as much as possible to facilitate future maintenance work. In addition to the above requirements, there are still some requirements that need attention, such as: carefully check those degreased parts to keep them clean; When installing test instruments, you must follow the corresponding installation instructions and try to keep consistent with the pipeline construction progress.
3 pipeline installation and construction technology analysis
The installation and construction technology of oil pipeline is a systematic project, and only advanced technology can guarantee the quality of the whole installation project. The corresponding construction technology will be described in detail below. (1) pipe section manufacturing. The manufacturing process of pipeline directly determines the quality level of the whole project. During the construction period, professionals shall be arranged to conduct a systematic and comprehensive inspection of the pipe network through advanced testing equipment. Once problems are found, they should be reported in time, and personnel should be organized for replacement and maintenance as soon as possible to avoid affecting the progress of the project. (2) Welding problem. During the installation and construction of petroleum process pipeline, attention should be paid to the weld seam of the pipeline, which is very prone to leakage. Details can often determine success or failure. Therefore, relevant operators should receive relevant professional training before taking up their posts, pay attention to details in the construction process, operate in strict accordance with the corresponding regulations, take effective measures according to the actual situation, and check in time after completing the work to minimize the safety accidents caused by welds. (3) Anti-corrosion construction. Due to the particularity of the conveying medium, there are strict requirements for the material of the pipeline, and corresponding anti-corrosion measures should be taken. First of all, we should choose the corresponding anti-corrosion materials according to the actual situation, and secondly, we should do effective anti-corrosion construction in the construction process. It is necessary to comprehensively consider various situations, effectively improve the corrosion resistance of pipelines, and then maximize the construction quality of pipeline installation. (4) Sealed installation. In the installation process, the construction personnel should pay special attention to the flanges and gaskets at the pipe joints. Once these two parts have problems, it will inevitably lead to leakage accidents and cause serious economic losses. Therefore, in actual operation, if the gasket is damaged or the flange is misplaced, it should be replaced in time. When installing the flange, the concentricity between the flange and the pipeline should be guaranteed, and the force should not be too strong when fixing, so as to avoid damaging the flange and affecting the engineering quality. (5) pipeline static electricity. In the installation process, due to the friction between pipe network systems, electrostatic problems often occur. In order to avoid the interference of static electricity, we can start from the following points: First, construction workers can enhance the ability of static electricity shunt by optimizing the design of lines; Secondly, the oil brush treatment of installation materials is best carried out after the installation is completed; Finally, in the process of pipeline grounding treatment, it is necessary to remove easily conductive impurities such as rust to ensure the firmness of the connection. (6) Bolt connection. When the pipeline runs for the first time, the change of temperature will often cause the deformation of the pipeline, which will lead to the loosening of the bolt connection. In order to avoid this situation, the construction personnel should take other fixing measures after the bolt reinforcement work is completed, and carry out double reinforcement to ensure that it will not loosen.
4 conclusion
To sum up, pipeline installation engineering and construction technology are very important in the petroleum industry, and the degree of attention to them will affect the quality of the whole project. Therefore, relevant enterprises should pay enough attention, increase investment in scientific research, explore new construction technologies, and ensure the smooth progress of oil transportation as much as possible.
