Source: Xinhua Net, Lanzhou. October 20 (Reporter Wang Heng) – China National Petroleum Corporation’s Western Pipeline Company announced on the 20th in Lanzhou, Gansu Province, that the refined oil pipeline part of this key project is now in operation. To date, 380,000 tons of refined oil have been transported from the first pumping station in Urumqi, Xinjiang. Reporters learned from the conference on the commissioning of the refined oil pipeline held by CNPC Western Pipeline Company in Lanzhou, Gansu Province, on the 20th, that on September 25 this year, the first batch of oil transported via the Western Refined Oil Pipeline reached Lanzhou after traveling along 1,842 kilometers of pipeline. It is expected that 10 million tons of refined oil will be able to be transported out of Xinjiang through this pipeline each year. According to Ling Xiao, chairman and general manager of CNPC Western Pipeline Company, the commissioning of the western crude oil and refined oil pipelines is an important measure in the context of the energy security strategy and the development of the western region. This year, China established the China-Kazakhstan crude oil pipeline, a land-based route for importing crude oil. The crude oil delivered to China can be fed into the Western Crude Oil Pipeline and then sent to downstream refining plants, or it can be processed in Xinjiang before entering the refined oil pipelines to supply downstream markets. In recent years, with the increase in crude oil production in Xinjiang and the expansion of the capacity of local refineries, the pressure to transport crude oil and refined products out of the region has grown. The existing railway transportation methods are insufficient to meet these transportation needs, while the oil pipelines in the western region provide a safe and efficient way for transporting oil products. The annual designed transportation capacity of the refined oil and crude oil pipelines is 10 million tons and 20 million tons respectively. Ling Xiao said that the western crude oil and refined oil pipelines, together with the China-Kazakhstan crude oil pipeline, will form a strategic corridor for transporting oil from the west to the east. This will connect the oil pipelines in Xinjiang, Gansu, as well as those in the eastern and southwestern regions, along with the petroleum and petrochemical enterprises, thus creating a oil transportation network in the west. It will enable the integration of resources from the west with markets in the east, which is of great significance for diversifying China’s energy supply and ensuring energy security. According to Ling Xiao, the main sources of crude oil for the western refined oil pipelines are the three refineries in Xinjiang – Urumqi Petrochemical, Karamay Petrochemical, and Dushanbe Petrochemical. The refined oil can be transported to the southwestern region via the Lanzhou-Chengdu-Chongqing refined oil pipeline. CNPC plans to build a refined oil pipeline from Lanzhou to Zhengzhou to Changsha next year, allowing oil products to be transported further to the eastern regions via this pipeline. The reporter learned that Western Pipeline Company is accelerating the construction of crude oil processing plants; the crude oil pipeline is set to be completed and put into operation next year. By then, the Western Crude Oil and Refined Oil Pipeline will become one of China’s pipelines with the largest design transport capacity, longest length, highest pressure levels, and highest degree of automation.

The longest crude oil pipeline: China’s longest crude oil pipeline is the Western Crude Oil Pipeline. The pipeline starts at the Wangjiagou terminal in Urumqi and ends at the Lanzhou terminal; its main line is 1,858 kilometers long, with a diameter of 813 millimeters. The designed pressure is 8 MPa, and the designed transport capacity is 20 million tons per year. It was completed and put into operation in June 2007. Once completed and put into operation, this pipeline, together with the China-Kazakhstan crude oil pipeline, will form a strategic route for transporting oil from the west to the east. It will enable the transportation of crude oil from the Tarim, Xinjiang, and Tuhua oil fields as well as imported Kazakh oil to downstream refineries, putting an end to the 50-year history of Lanzhou Petrochemical relying on railways to supply crude oil to its plants.
Only by knowing about these two pipelines can one understand why such a large amount of crude oil and refined products is transported from Lanzhou to the southwest and central China regions

More crude oil will be available once the Mahu Oil Field starts production
Recently, with the strong support and cooperation of the Beijing Oil and Gas Regulation Center, the trial operation and commissioning of the Aduwu-Shanxi Unified Hydraulic System project operated by CNPC Western Pipeline Company marked the achievement of the capability for both sealed and open transportation within the western crude oil pipeline network. Previously, the crude oil pipelines operated by CNPC Western Pipeline Company – the Adu Line, Duwu Line, and Wushan Line – were physically connected but operated independently of each other. To make effective use of the residual pressure from oil flow in the upstream pipelines, after nearly 5 years of thorough evaluation, as well as assessments of process operation safety, modifications to equipment and facilities, and adjustments to surge protection procedures, the company has optimized and integrated the Adu Line, Duwu Line, and Wushan Line into a single hydraulic system, taking into account energy savings, reduced consumption, and operational safety. Experience has shown that, under the same flow rate conditions, 3 fuel supply pumps can be eliminated, thereby reducing the operations related to the transfer of crude oil into storage and the associated risks. The commissioning of the Adu-Urumqi unified hydraulic system project, together with the previously operational Luntai-Urumqi unified hydraulic system project, has reduced the six hydraulic systems of China National Petroleum Corporation’s western crude oil pipeline network – namely the Adu line, Urumqi-Adu line, Urumqi-Urumqi line, Luntai-Kuqa line, Kuqa-Urumqi line, and Urumqi-Lanjiaogou line – to three main hydraulic systems centered around Shanshan: the Adu-Urumqi-Urumqi-Shanshan line, the Luntai-Kuqa-Urumqi-Shanshan line, and the Urumqi-Lanjiaogou line. This change not only simplifies the operation method but also reduces pipeline energy consumption costs and operational risks. (PetroChina, Yin Jing)
The Mahu Oil Field is a gravel oil field of 1 billion tons in scale, discovered by CNPC Xinjiang Oilfield Company after years of exploration efforts in the central area of the Mahu Depression in the Junggar Basin. Its tertiary petroleum geological reserves amount to 1.324 billion tons, of which 0.481 billion tons have been confirmed as reserves; it represents an important area in China for increasing oil reserves and production. According to the plans of Xinjiang Oilfield Company, the pace of exploration and development in the Mahu area will be further accelerated. During the planned period, over 10 million tons of additional production capacity is set to be created, and by 2025, the annual production of the Mahu oilfield is expected to reach 5 million tons, with stable production levels maintained for 10 years.
In the past, our country only used the Reibin formula; it has now been found that if there is a lack of proper understanding and basis regarding the formula itself as well as the values associated with roughness, then in practical applications errors in power calculation of up to 40% or more can occur. This is not feasible in the design of large oil transport projects with capacities of tens of thousands or even hundreds of thousands of units, and it must be addressed carefully.
What is the Reebin-Zorn formula? ? ?
