In the next five years in China oil and gas pipelines under the background of building huge quantities, China petroleum based on the second line of west-east gas, oil and gas pipelines in myanmar at home and abroad, such as key pipeline engineering, vigorously developing the pipeline construction of new technology, new technology, new material, new product development, grasp a series with independent intellectual property rights of the core technology, proprietary technology, characteristics and key technology technology, west-east gas transmission for three, four, five line do sufficient technical reserves. This is a reporter from November 20, in our country "pipeline" Hebe langfang held China petroleum and natural gas kindly 7 th science and technology innovation of science and technology of congress seminar of the learned.

  According to China's oil and gas ZhaoYuJian kindly chief introduction, the next five years, China's oil planning new pipelines are a total length of 40000 km above. So a huge amount of pipeline engineering, through complex geology, engineering construction technology, time, quality, safety, environmental protection etc are put forward more severe challenges.

  He said, "1025" period, China's oil will invest in technology funds of 120 billion yuan, is the "eleventh five-year plan", the two times, including pipe technology research and development spending will have quite proportion. Kindly will focus on the future of the pipeline project technical problems, pipeline in service operation technology service requirements, as well as main business extension of the key technology needs, and carry out the major technical research, realize the major breakthrough in the following respects: one is 0.8 strength design coefficient and 1422 mm pipe industrial application accessory construction technology. According to draw up in west-east gas transmission line in three of try to use 0.8 strength design coefficient of the requirements, and draw up in west-east gas transmission four lines, five line application 1422 mm, 12 million mpa, X80 pipe scheme requirements, the revision current design standards, and carry out welding, anticorrosive, cold bending, construction technology research, complete 0.8 strength design coefficient, 1422 mm and 12 million mpa, X80 pipe steel industry application period of study. 2 it is X90 / X100 high steel grade pipeline construction and technology. Summary X70, X80 has high steel grade pipeline steel application research experience, increase X90 / X100 steel grade pipeline engineering design, welding, construction, fittings, and other aspects of the research, form X90 / X100 high steel grade pipeline construction and technology, maintain high grade pipeline steel kindly in the leading position in the field of construction technology. Three is pipeline crossing supporting technology. In view of the current existing in the pipeline construction through engineering problem, careful analysis and comb directional drilling, shield, pipe jacking technology situation, the combination of related domestic research institutions, strengthen the research efforts, break through the core technology, improve the construction process, improve and integrated pipeline crossing supporting technology, perfect the pipeline crossing technology system for the construction of key projects to provide technical support. Four is the ocean pipeline construction technology integration. With China's oil subject "within 300 meters water depth ocean pipeline construction technology research, as an opportunity to increase investment in science and technology and the Marine business research efforts, integrated shallow offshore pipeline construction technology, promote ocean pipeline construction technology kindly progress and business development. Five is LNG terminal and trunkline construction technical reserves. With large LNG terminal and trunkline design for its source, and carry out large LNG terminal and trunkline design technology, tank installation technology, contract management technology research, through two years of technology research and reserves, for smoothly into the business areas lay the foundation.
